Fix it Frank is the BEST. Thank you so much. I have a JVC DLA-RS4910U and had figured it was the ballast based on what it was doing and you description. Took a gamble and bought a new ballast and used your video as a step by step guide. Although the model was not the same, the repair was essentially identical. Now I don't have to go buy a new projector. Thanks again.

Thanks so much Jeff! I will add, that if you can afford it, invest in an always on UPS battery backup that will handle your projector. I run a Tripp Lite (eaton)brand UPS that is always on, and true sine wave(Dual Conversion). It wasn't cheap but now I have filtered power that will never spike or dip. My local power grid fluctuates as much as 10-15 volts throughout the day so this UPS really helps. It also gives me cool down time in the event of a power failure while I'm watching a video(not a common occurrence but a nice feature to have). I look for used UPS's on eBay (APC Smart-UPS or Tripp Lite Dual Conversion type) and then buy batteries on Amazon. You can get them way cheaper that way.

Frank, I managed to repair the ballast, all it was an smd capacitor(4.7uf) on the control board was shorted. The capacitor is located above #68, the bigger one. Just below the 73832 IC(the one from the edge of the board). Found it with a Flir E4 gun. I can't believe a tiny component, can bring down a mighty device like this. Not a bad purchase for $60.

I know they will last for a long time, but input lag is on the high side and since I primarily game on the projectors I look at cheaper more gaming oriented models. Nice repair Frank, stunning to find out that this machine can operate on a different type of ballast! The things you learn..........

Believe it or not ballasts are kind of cross compatible. It's basically just a power supply that drives a lamp. Not much different than a fluorescent driver or led driver. As long as you match the important specs close enough, you can use a lot. I tried a few just hanging outside the projector until I found one that worked properly. Usualy the 230w ballasts that Benq uses are popular in other models so I use lots of those. But this JVC and a few others I did were pickier but I am not sure why. I suspect the communication or the ignition voltage.

Are you of the opinion that only the socket has a defect or the Hdmi chip? If it were the chip, all 2 connections would not have to work, I think. What is your experience about it, is it fixable? Is this ballast board swap 230 volt or a US 110 volt swap? Thank you for the insight of a JVC RS 57.

It is possible for part of the chip to be bad. I saw that with a Sim2 that used one chip for HDMI. I would check the TVS diode array in the input first. If they check shorted to ground they are the issue. Otherwise it may be a new chip or rather just use hdmi2. The chip may need firmware loaded if replaced and that might be impossible to source. The ballast actually run on 380vdc. They are powered by the pfc circuit in the power supply and that can run multivoltage (90-250 50/60hz).

I left a few other comment before related. So thankful for you providing so much free documentation on various different types of projectors. You're an amazing individual. As luck will have it, based on the warning led codes and some internet research. I'm pretty sure my fault is exactly the faulty ballast in this video. It even seems it's the same chassi so the interior design I would assume is similar aswell. Lucky me. Might not have to use this as a fancy paper weight afterall. I was thinking since this x700r uses the same compatible replacement lamp as the rs57 in the video, do you reckon I could borrow your hassle of trial and error and use a euc 210d n/t01? Id have to open it up, buy a multimeter and see if the voltages seem similarly wrong. Exciting and scary experiences ahead. Then from my understanding the same lamps will still work as originally designed, I don't have to buy a lamp that now fits the euc 210d n/t01 ballast do I? Any general tips as to how I should proceed or thoughts on my project? You're the man Frank. When shopping for multimeter, since I'm new to these, are there any particular that is nessesary for projector type repairs?

Thanks for all the kind words! I'm nothing special. I just want to share what I learned and hopefully help folks like you keep your projectors running without breaking the bank. You can most definitely try that ballast in yours. Fortunately the design of both the ballast and mains power supply are built to protect each other. Worst case, the lamp won't light. And you are correct in that you can just use the original lamp assembly. As long as the ballast rated power is close, it'll be fine. In your case it's close enough. Connecting it up and you should either have a working lamp assembly or if it's not compatible it'll ignite and then turn off and give a lamp fail warning. As far as meters I believe in spending the money since I use it constantly. My fluke 87v was around $500 new but for most people, a cheaper fluke 15B or similar is perfectly fine. I'd stay with fluke if you can afford it. If not there are some cheaper name brands out there. Really any meter is fine but I like fluke for the insulation quality and general quality of the construction. The main thing you want to check, is make sure you have the 380vdc to power the ballast. If it sits at 150(USA) or 300v(Europe etc). The power factor circuit isn't working and you have a mains supply problem.

The original ballast is 230W, so if you use a 210w(EUC210), there will be 20 less watts of drive power for the arc lamp. There will be a very tiny decrease in light output but it is not very obvious. The T01 v T05. I am not sure. It must be an option code. When I first found I could substitute a ballast, I used a very basic method of picking up a pile of 200-230W ballasts of different types and plugged them in. I found that if the ballast was physically the same size and had the same control connector, they would work. The smaller ballasts(from a BenQ w1070 for instance) would turn on for a short time and then turn off. You can also repair the old Rubicon ballast if you purchase the output IC and replace that component. Grazie per le gentili parole! La mia famiglia è Abruzzese.

Hi Michael, I do not have a cleaning video on one of these yet. I hope to make one eventually but the only way I can usually do these is to have someone send one in. Hopefully this video will spur that. Until then, I would not use compressed air as you are hearing. It can be used but only if the unit is really really dusty and even then you will need to go in with a vacuum and dry brush to get the dust that gets pushed into the optic assembly. The problem with compressed air is that it can push dust into places it was not in before. sometimes you need to use it though, if the fans and all are really packed with dust. I would suggest using a vacuum instead and then get a dry paint brush with soft bristles and use that to loosen the dust that you can get to and then the vacuum will pull it out. If the picture is good, I would not bother opening the unit and instead clean at the vents and maybe remove the lamp and vacuum inside that area. Less is more with these projectors. If you open it up and bump a LCOS panel out of alignment, you could be in for a bad experience. I would only take it apart to clean if you notice dust in the image.

Frank, what if the PS is not putting out dc voltage to the ballast? Is there a way to test the PS components? Had to spend 250+ on a PS if I can fix it. I'm only getting like 2 VDC out of the PS.

There's a few. Id start at the AC in and check the fuse and NTC thermistor. Then make sure the door switch for the lamp is closed. There is a pair of resistors(big boys) the couple the negative side of the bridge rectifier that can go open. You should have that 380 when it's working or at least 150 if the DC is being fed without the pfc circuit running. 2v makes me think you are reading inductance and you have no mains power getting to the bridge or bridge is not feeding the rest of the Power supply. 250 is a bit high for a power supply in my opinion but that's a really nice projector so...maybe it's worth it. If you want, email gydz@timeprojectorlamp.com. It's a parts contact I use. They may have a recycled power supply you can buy for a better price.

@@FixitFrank awesome Thanks for the input! I did find the resistor right next to the 400dcv out was shorted... According to the color bands it should have been around 36.8ohm but I was getting less than a ohm across it, just slightly higher than my meter leads. Couldn't find a direct replacement, but I did find a 30 and a 6.8 that I just wired in series for it. Now that that's in I'm still not getting 400 out of it but I think I have too much disconnected I'm going to start putting it back together and see what I get going forward. The balast in it is a rubycon rpb-0526ga and looks BRAND NEW. I'm suspicious of somebody already trying to replace it not realizing that the power supply was bad.

Thanks for this video, very helpful. I have a DLA-X700RBU screen started flickering and eventually (couple of weeks later) unit shutdowns after 30 seconds and displays an intricate error series of blinks. Changed the lamp and while the image is perfect (For 30 seconds), it still shuts down 100% of the time and presents the same error. Communicated with JVC and their response "It appears be some kind of internal processor issue which requires internal inspections." Found that there was a capacitor on the projector’s front IR/LED board installed backwards that was installed backwards on RS40's, checked that capacitor but it is installed correctly. Any thoughts on my next step? I am going to clarify with JVC and hopefully get a part number, but when they say "processor" do you think they are talking about the main board? Thanks again.

I kind of doubt it's a main board (internal processor) failure. The ballasts seem to have "glass chins" meaning they are pretty delicate. From your description, I'd be checking the ballast. Make sure you have the 380v power to it. If so, then I'd be trying a replacement ballast.

Sounds like your PFC circuit is not working. 220ac will give you about 300(290-300vdc) rectified. The PFC circuit should enable and you should see 380V there. It sounds like your ballast might be okay but test that wire without it plugged into the ballast. If it does the same thing, you have a mains power supply problem. Check all the components that feed that power to the ballast. If unplugging the ballast causes the 380 to return, then you need a ballast.

@@FixitFrank Thanks again. The 289vdc reading was across the two pins the ballast connects to without the ballast plugged in. The unit shut down and displayed the error both with and without the ballast plugged in. Unfortunately I'm a Mechanical Engineer, so while I feel comfortable troubleshooting / performing the work I'm unsure exactly how to continue to trace the problem upstream. Any additional advice on where the PFV circuit is located and how I could test that?

PFC is located in the mains power supply board. You may want to locate a service manual. Sometimes they are free but even the paid versions are pretty cheap. That might be your best next step. Make sure you are comfortable dealing with the potential medium high voltage. (380 can hurt you pretty good). Are you in the USA?

@@leefrost5304 thank you! That helps a bunch. I have a theory that its overheating. Either a fan is clogged, not working, failing or something like that. www.projectorcentral.com/pdf/projector_manual_3536.pdf on page 41 they have a chart that points to a few possibilities but being that its on for about 20min before it shuts down, I am leaning towards a cooling problem. I suspect your ballast is okay and if you take it somewhere, have them check all the fans for operation and to make sure they are reporting the proper RPMs.

Which Ballast is in the X3? I ran into this when I was going through my ballasts. I think its because of the wrong level "lamp_on" reporting signal. Might need a resistor change.

In the meantime, let me know what is on your ballast and I can keep looking at these.

From the moment I press the "power button" after 1 minute and 15 seconds exactly the lamp turns off, goes into stand by mode. Solid red standby light, 2 orange flickering lamp light, solid red warning light. At start up it displays the logo and will display an hdmi signal then with no warning it just shuts off.

Thanks so much for this content! I have a JVC RS 500. How would I check if there's a problem with the Optical Block? I've stripped it down partially, but don't know what I'm looking for exactly. The issue I'm seeing, that some people on the internet confirm is an optical block issue, is I put two new bulbs in the unit and the total light output is still much lower than expected.
@FixitFrank
10 ай бұрын
You're welcome! That is honestly a tough thing to diagnose. You really need to rule out what isn't causing the lack of brightness. I have not personally dealt with too many JVCs that have had optic block issues that are as new as yours. It's not more than 8 and no less than 5 years old and that should be within the expected life span. To check the optic block, you need to carefully check for any discoloration on any of the coated glass you see. try not to take anything like a lens or mirror out and leave the display panels as they are. if you knock anything out of place that needs alignment, you will be in a world of hurt. The pieces I would be the most likely to check first would be the lenses right after the lamp. Id look for burnt on dust, coatings that flaked off. that sort of thing. If you wipe anything, don't use any cleaner. Use distilled water if you can, at the least maybe filtered water. I like to use photo brushes unless its real bad. Then I will use chamois swabs. When did this all begin? Aftermarket is usually fine. The pkl2615u is fairly straightforward. As long as it has an Ushio or Matsushita bare bulb, that should be putting out the right amount of light. Are they aftermarket or did they come in JVC boxes? Most of the time, I find the lamp is the root cause. I know you said you tried two lamps though. Were they from the same vendor? Where did you get the lamps if you don't mind my asking?

Ah okay. MyPL is usually okay but take a look at the lamp and see if there is a silver sticker with a 4 digit number and a serial number starting with 23. If not it might be a knock off. Mypl sells APOG aftermarket lamps as well as some others. if its the silver sticker lamp then it should be fine. if its not, that might be the problem. but since it started on the old lamp and it was obvious, I'd be suspicious of the auto iris. See if disabling or changing the auto iris settings change anything. If the iris is jammed or has some debris blocking it, this can happen.
