Question about Mitsubishi WS-55613 55" Rear Projection HDTV
Yesterday I moved my TV and entertainment center from my living room to my family room. I hooked it up the same way, cable using component1 and PS3 into input1. Now the I only get a blue screen switching inputs, I got the cable going into ant1 just to watch it. I tried to reset factory default, didn't do anything.

The Sony outputs 180P, not 1080i. There is a difference. I don't know what exactly, but Sony says 1080p is for superior.

I finally got around to dismantling the TV. This is no mean task. The chassis is tethered to the rest of the set my over a dozen wiring harnesses and a few of these cannot be disconnected near the chassis but instead require removing the “right support” near the air duct and taking the shield off the lamp ballast. Once the chassis assembly is out, it is a further significant task to disassemble it to get at the various PWBs (POWER, FMT and DM) having the suspect caps. I’m sure reassembling everything will be a fun job!
I have not yet had a chance to fix and reassemble but I wanted to post this no as I’m not sure when I will get around to it.
I did find six of the fourteen known-problem caps to be visibly bulging -- both 3300s and two of the four 1000s on the PWR PWB plus two of the four 1000s on the FMT PWB (see photos below). Ironically of the four 1000s on the DM PWB, which I have heard are the most common to go bad, were bulging and I considered skipping these as the DM it is the toughest board to extricate from the chassis, however I figured I had come this far and I would just as soon replace all twelve 1000 uFs as the parts cost $0.23 and I really never want to have to do this again.
If I had to bet, the two 10V 3300uF caps on POWER board, which were actually leaking black goo, are the actual culprits, but with four of the 1000 uFs also bulging it is probable only a matter of time until they failed as well.
Here is the POWER PWB with the known-problem caps (C9A37, C9A38, C9A51, C9A52, C9A61 and C9A62) highlighted:
here's the FMT PWB with the known-problem caps (C8F19, C8F21, C8F22 and C8F27) highlighted:
and the DM PWB with the known-problem caps (C81A2, C81A3, C81B3 and C81B4) highlighted:
Here are close-ups of the bulging caps (C9A37, C9A38, C9A52 and C9A62) on the POWER PWB:

SOURCE: No video in any of the TV inputs
first try resetting and rebooting. reset = menu, 2470, enter.
reset is press reset button and wait for green lite to stop blinking.
if that takes care of it great. if not it sounds like a signal board or dm problem and will need repair. check out www.tv-techs.com

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.
Common Symptoms include....
Here is a quick test....
Using your original remote go-to the settings menu then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move RED and BLUE in all directions - up, down, left, and right.
If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.
Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
