Question about Mitsubishi WD-52525 52" Rear Projection HDTV

2 Answers

The picture on our Mitsubishi WD-52525 has what seems like hundreds of horizontal green lines. These lines move down the screen in a sort of haphazard scrolling fashion. over the picture. There are also small little white stars that flash over the picture. Turning the TV off and on does not help. The sound is still working. The TV device menus appear as normal. The problem is the same with the dvd player, playstation and vcr. In one of your threads someone mentioned that we need to replace the capacitors on the FMT PWB this is a common problem with the V26 chassis which is what our model number is. They have some bad capacitors that need to be Changed. There is a repair Kit available for the FMT repair. Can you please send us the link for the repair kit or instructions on how to repair this ourselves? Thank You! Jay Ray

    My Mitsubishi WD-52825 was having picture issues, green horizonal lines
    through the picture. Took the advice from this forum and replaced 12
    bulging capacitors on 4 different boards. Put everything back together
    and turned on the TV. All I get now is a static tweed like pattern on
    the screen. I know I need to reinitalize the setup of the tv after
    unhooking everything. But I can't even get to the menu (tv menu,
    2,4,7,0) to complete this. Is there another way to reset the hard
    drive? I have reset the TV and pressed Menu, Device on the TV. There is
    no error code, just code 12. I can not get past this tweed like
    pattern. Please help!

    Thank You,

    Is the DVI cable the black cord with the white head and the two screws on each side that screws into the side of the fmt board?

    I dread taking this whole thing apart again... ugggg. I will also check all of the ribbons... is it the orange ribbon on the top or one of the white and blue ones on the bottom or side, that could cause this problem?

Disassembly for this unit is very difficult. This model has bad caps on the FMT board but also on the DM and power board. I recommend getting a service center to send the whole chassis into Mits for a rebuild and get it all fixed. If you think you can do it yourself, you'll need 12 680uf caps for all 12 of the 1000uf that will dome (mushroom) up when they go bad, also two power caps 3300uf caps will go bad on the power board. The disassembly/instructions could likely fill a small book.

    problem has to be somewhere between the last stages of the chassis and the engine. one of the ribbon cables is likely not seated all the way. it is very tricky to snap some of the ribbon cables into the connectors and still have them going through the ferrite beads. i would try reseating all the ribbon cables inside the chassis and hopefully this will fix the issue. if you cannot get menu, the problem could be engine related. the big DVI like cable is where all the picture runs from the chassis to the engine. check this cable for good connection and no bent pins. I believe sometimes other caps on the power supply can go bad causing engine voltages to drop low and give grid pattern symptoms.

I am having trouble with my Mitsubishi 52" DLP model WD-52525. It has large green horizontal stripes rolling up and down the screen. I have already paid my money here, and was disconnected before my chat...


There is a chance the video board is not working how it should. When a video board starts to fail it can start with these green lines and it can also give you a completely green or blue screen. In this case you need to take the board to a shop so they can check if it's either the digital or analog video board. The boards are not that expensive. http://www.discount-merchant.com/?Click=48427

Green horizontal lines on screen no picture


The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

You would need the service manual for that adjustment. It is outlined in the service manual on how to adjust the tilt. It is a mechanical adjustment. You can get the service manual emailed to you instantly after purchase at this link.
