Question about Mitsubishi WS-55909 55" Rear Projection Television

1 Answer

Picture was fine, then lines diagonally, now light

Picture was fine, then lines skewed diagonally, then became light green background with red and blue lines bowed about 1 inch apart. The set turns on but will shut down about 30 seconds later and have tried rest several time.

The Blue lamp is no longer projecting. Is this as simple as a lamp replacement? Can I check the resitance through the lamp to be sure that is an issue? The set is 7 years old with but has less then 4000 hours on it so I really do not want to replace it yet.

    Figured out the issue. the Netcommand set up was for composite HD input and I was using component. The tuner compensated for a while.



    Didn't touch the TV over the holiday's and recently reconnected with the standard 480P inputs. TV worked fine so I moved the connections back to the 1080i inputs and and also reset the netcommand assignment. That is when I figured out I was using the wrong setup.

    Problem was the Netcommand defaults to composite HD inputs. I was using component inputs. The tuner compensated for while.

    Deleted all the TV assignment and setup Netcommand again. No issues now.

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the 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,Mitsubishi,Zenith, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hitachi 65F59 65-Inch CRT Projection HDTV picture skewed.

The convergence output IC's have failed and need to be replaced. Sometimes when they go biasing resistors burn open also. These are large amplifiers mounted to heat sinks and have as many as 18 pins soldered into the circuit board. Better be handy at desoldering even if it's only the IC's that are bad.

Picture Problem

In that set its usually a bad picture tube. The lines you are seeing are called retrace lines. You can take it to a shop and they may be able to rejuvenate the tube

Too much green color

Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.

Mitsubishi 55" big screen TV powers down after 70 secs We had a power outage in the neighborhood, after which our Mitsubishi 1080 HDTV WS-55909 only had a blinking green light on the front (no variation or pattern), even after the set was powered down. Upon reading online, it appeared the DM module capacitors were the likely culprit, so I sourced (7)1000 microfarad capacitors and replaced them, then reassembled the TV. This was the first time I'd soldered on a circuit board, so of course a lot of things might have gone wrong. However, after that the TV now powers up, but I only have a blue screen and cannot get the remote to work except to power the TV on and off (tried changing batteries in remote, reprogramming remote per setup manual, etc). Further, the TV powers off after 1 min and 15-20 seconds. I then tried to see if I could get any of the attached devices to work on their own with no other devices on except the TV. Each of them yielded a blue screen (X-Box, VCR/DVD recorder, Wii, cable) except the DVD player -- which displayed a great picture! The problem is the DVD will play 1 min 15 seconds then the TV will shut down and the green light will blink steadily (no pattern) for 60 seconds, then power down. And this only works if the DVD is on before the TV is turned on, and since the remote doesn't work I have to press "play" on the DVD player. The DVD is hooked to Component Input 2 so that input appears to be working fine. The VCR/DVD recorder is attached to Component Input 1. When I had it powered up and turned on the TV, I got a blue screen. However, when I left the VCR/DVD on and then turned on the DVD, there were jagged lines on the TV for 3-5 seconds, then the TV made a popping sound and shut off. When I then turned on the TV (i.e., with both the VCR/DVD and the DVD on first), the DVD worked but could not switch to the VCR/DVD without the TV turning off. I also tried switching the cabling for the DVD to Component Input 1, but the DVD no longer worked. When I tried the VCR/DVD on Component Input 2, it still only yielded a blue screen. So is Component Input 1 bad? And why would the TV work with the DVD in Component Input 2 but not the VCR/DVD? Obviously I have multiple problems here. The first one to deal with is the TV shutting off after 1.25 minutes. I am unable to see where I can get an error code when the blinking light just blinks quickly without any pattern, and neither the front panel controls nor the remote control work. Perhaps most of my inputs on the rear of the TV don't work now except Component Input 2 but I don't know how to test this. So I made a little headway with the capacitor replacements, but not sure what I can do at this point. Any suggestions? I've seen references for other Mitsubishi big screens that shut down like this, and the fix was related to the output power module, but not sure if it applies the the WS-55909. Thanks in advance for any help you can provide. estout7
