Hey all, well I have the dreaded light engine problem. However, all is not lost. I have completely dis-assembled my light engine and have found my issue. There is a small light filter assembly in there with the numbers >PC-GF20< on it that has a burnt tinted plastic filter piece on the glass. It is keeping the blues from reaching the mirror in the top of the TV and thus I have no blue on my set. Do any of you have a dead light engine that I can rob the >PC-GF20< out of? It's a REALLY cheap part and I would love to have it. It would make my light engine basically like new. Thanks!

It's normallt only available as an assembly.
Maybe you could ask some sony repair shops.

I actually fixed the light engine myself. The red blobs and lack of blue comes from the tinted pieces of tape that they put on glass panels that are between the LCD panel and the concave lens that ultimately gets combined to form the picture. My blue is back and my red is no longer blurry. Too bad my settings are borked and I can't get them back into something that is closer to looking good. I have all three colors now and they are clear. I just can't get them to look normal together.

That is because you really need to replace the entire light engine...

Or, you could try going into the service menu and attempt to 'unbork' the convergence.

Hi,Its common for this lcd tv's (specially Sony)To have an issue with their Lcd chips,you won't find them anywhere else but maybe in a repair center.Make sure you get the ones from your tv,otherwise you will need to replace the light engine.Good luck and God bless you!

OK, I learned a lot but did junk the TV. I'm selling lamps and power supply stuff on eBay for cheap. The glass filters were easy to rebuild and I actually improved the picture but I later learned that the red LCD panel inside the engine was cracking and wasted. The green and the blue LCD's were fine. I would have been able to fix had I been able to find the red LCD panel. But, from what I've been reading the red panel is the one that fails first. So, I trashed it. Good thing I only paid $50.00 for it. At least I learned A LOT about DLP TV's and realize I will NEVER buy one.

Sorry, but the 50V500A is an LCD-RP TV.

With the proliferation and price of direct view panel flat panels, the rear projection TV market has just about dried up.

I need two of those light filters and a red lcd to fix my engine light, can you tell us how did you fix your engine light and where did you get the filters?

Thank you

Try Tri State Module. They rebuild the optical blocks or do an exchange for Sony, Hitachi, Panasonic, etc. This is especially useful for those who didn't get the warranty work from the manufacturer. My Sony unit was replaced under warranty and I haven't had any more blob issues with the new unit. Because of the intake design you may have to go in and blow the dust off of the lenses every couple of years but in my book that is pretty easy stuff. I do not like the look of movies on the new LCD flat panel sets and am extremely happy with my Grand Wega.

Okay, I looked up their website, and it says repair price yada yada. Does that mean they actually do the repairs to the part or if you get the part and it breaks they will repair it for that much. Pardon me if I sound stupid, I am new to this rear projection tv stuff and I am trying desperately to get mine fixed.

It means you send them the whole light engine and they rebuild it and send it back to you. If they happen to have a rebuilt one in stock you can also buy it for a bit more money.

I would be careful in concluding that you need only the input-polarizer on the blue channel. Typically it's the LCD panel in the blue position that goes bad on these sets. A bad LCD panel causes the slowly moving blue-blobs effect and of course the dead blue pixels. You may need both the polarizer and the panel.

Well I really am not entirely positive what it needs. But it has the yellow glow, and green tint. And from everything I read point to the light engine needing repair. Let me know what you think it sounds like.

The light engine is certainly the problem, and if you get it rebuilt they will take care of whichever parts are at fault, whether blue panel or blue filter or both or something else. All are parts of the light engine.

The decision, -is the tv worth to you what a light engine rebuild costs.
