Is it an LCD or DLP? The Model below suggests it is an DLP. Sounds as if you have the dreaded light tunnel collapse common to all LG 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. Good Luck.

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

Have sound but no picture. We have comcast and can only see a small screen in upper right corner after pushing the menu button. In this picture, I do see my comcast channels and I am able to change them...


Look inside front panel under RHS picture tube for leaked fluid. If you see a puddle on signal board, take tv to street - it is unrepairable then. The coolant is poisionous.
If that looks ok, then make sure you're using original Mits. remote.
Hope this helps.

Do we have to manually set the pix set key for every station/show we watch? We loose scrolling writing at the top and bottom of the screen on my dad's new 32" lcd tv bought at Wal-mart. When we set...


Thanks for the offer but we cannot afford to pay additional money for something the Factory support service Should provide.

From what we have heard through the Verizon installer, our SANYO LCD TV probably does NOT have a Automatic picture adjust system. That would most likely be the reason for the maunual button on the remote control. The troublle is that with the FIOS service, you do NOT use the TV's remote control. That leaves to switching back and forth between two different remotes wiich can be vary confusing for someone that is not 88 years old.

It is bad enough that you have to remember which channels you have to go to to receive HD programming signals. If I were making a TV set, and or running a TV network/ cable service, I would transmit both HD and regular signals on the same channel number and let the TV and or the decoder box figure out if my set could display High Definition. Isn't that what we spend lots of money buying equipment and paying each month for service?

If anyone out there knows if the SANYO 32 inch LCD TV sold at Wal-Mart automatically adjust to the picute format, (PIX 1-4) we sure ould like to hear from you.

Cleaning rear projection screen


I read in the manual for the Sony KDF 50E3000 that you should use warm soapy water on a clean cloth if you aren't able to remove it with a dry cloth. I find that the microfiber cloths work best.
