Question about Mitsubishi WD-52525 52" Rear Projection HDTV
Hello, My 1 year old Mitsubishi WD-52525 DLP HDTV has started having probem with the display. Earlier in the week it looked like my cable signal or something justseemed to be getting worse, then all of sudden yesterday I turn the TV on and the display is mainly horiziontal lines sort of moving up and down to different heights on the screen. Occassionally the image will work itself out and come back on the screen, that deteriorate back into the horizontal colered lines. I tried various inputs(coax, component, yellow, white, red,) and various sources such as DVD, cable, vidio games, but they are all equally messed up. Nowm if I am going through any of the TV menus and not actually using a video signal, the TV displays all the menus and stuff perfectly. Any idea what the problem might be? Thanks so much for any suggestions you can provide? Also, is it worth my money to by a service manual for this TV in order to try to fix this? I haven't ever used a TV service manual so I am not sure how helpful they are. Thanks again! Kyle
I repaired 3 sets and found many surface-mount caps were bad on four boards. After using an ESR meter and finding so many bad caps, I ended up replacing most of them (about 100). The parts were cheap, but it took me about 10-12 hours to repair. I've seen so-called capacitor repair kits on the web that only address the large caps on the power board. You can buy these individual caps at Mouser.com for under $10.00. Luckily people toss these sets so I have 3 awesome sets that only cost me labor and about $30.00. Sorry for the bad news about the caps.

I'm having the exact same problem! This morning it was working fine, now this afternoon the screen is flickering, mostly blue with a lighter blue area in the center, lots of vacillating vertical lines, and the menus are distorted and jumping around the screen. The TV responds to the remote but switching inputs doesn't help (some are more black than blue and have even worse display of tv menus). Does someone have a solution (other than "if you wouldn't fix a nuke then don't try to fix a TV")?

Now if you had a service manual, what would you do? or Test? These are not things that you should experiment with fixing as they are very unforgiving. If your not experienced with DLP TV's then you should seek out a pro to assist you unless you got tons of cash to throw around and start to replace boards. As once you buy a board, its yours no trying and taking back my friend. would you work on a nuck missle?? its the same as you have no know how on either.. Good Luck
