Thanks for the picture - that's a big help.
It looks you have the dreaded light tunnel collapse common to all LG1.gif DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps.
Hope Ya Fix It!

Mitsubishi WS55315 rear-projection has gone dark


Yes, they have other than convergence circuit problems----very few issues or troubles.

You should test the shops by asking if they have the 4 digit code number for this model for the OPTION MENU---set has 3 hidden menus and OPTION menu will allow a hard reset of entire set---the other two menus are adjustment and convergence menus.

If some shop has no idea what the option menu is----pass them.

Lg plasma has a black screen but has sound


If your screen stays black with no sign of light even when it has been on for a half hour or so, suspect the Y sustain module as the cause. If you can see a faint but very dark picture after a half hour or so, suspect the Z sustain module. In either case the problem usually occurs after hearing a very loud pop. Looking from the back the Z board is the large board on the right connected to the ribbon cables from the plasma display. The Y board is the large board on the left with the big square heat sinks. The Y and Z boards are the most common cause for the symptom you described. The boards may cost about $250 ea. There is a white sticker on the board with the LG part number.
Good luck.

Red light stays on


First before a reset the set must turn on, if the set just sits there with the red LED on you have further problems, so does the set display anything?
