Question about Toshiba TP50G60 50" Rear Projection Television

1 Answer

Lost color sync

My TV has just recently been loosing color sync and I get the rotating color bars. I took a color TV repair course years ago and know that the sync oscillator probably needs to be adjusted to bring the color back in sync. Do you agree? If I am right where is the adjustment. Is it an adjustment that can be made through the menus or is it a physical adjustment inside. In either case where? If I am wrong then what do I need to do? By the way I have noticed that the color sync in the picture in picture is fine, just the larger screen is messed up. Thanks in advance.

Samsung 40" flat screen looses sound


this problem started on my LN-S4051D a couple of years ago. eventually the sound stopped working altogether. I then started using my surround sound speakers for the TV via optical out but soon that stopped working as well. I recently took the TV to a repair shop who said that the main board is bad and needs to be replaced. Labor plus parts was going to cost me $400. I said no thanks and paid for the estimate. Good luck.

Discolored Sides


Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.Ths if your tv is a dlp if its a Lcd it will be an issue with your light engine: Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

There are 3 components that control color, and it sounds like one of those are bad.
You will have to get it repaired.
I would talk to your local repair shop, and see what their estimate is, before deciding on repair or replacement.

Hitachi 50UX18B/19K - FREQUENCY INTERFERENCE ?


Well, thats 12 years ago...and in human years that a blink of an eye..in TV years, its a lifetime. It sounds as though the power supply is leaking AC into the circuits.
That being said...now what. The reason that TV repair shops are dropping like flies, is that there is no way to make money in TV repair. The local repair shop here charges $75.00...JUST TO DO A QUOTE. Now, I can mosey down to Wal-Mart, and buy a really nice TV for around $150 that is bigger, and looks better than my dead one...so what are MOST people going to do. Ok, I know...a wal-Mart TV isnt probibly going to last as long as your old one...as a matter of fact, it will probibly last only about 4-6 years, but, it costs probibly a quarter of what you paid for your original TV, and only a bit more than you will pay for your TVs repair.
Even a small repair is going to take 2 hours, and at 35-45$ a hour..it just aint worth it. As well, to keep costs down, most manufacturers are dropping any sort of parts support, or tech support, so specific parts are getting impossible to find.
....its a whole new world...electronically that is!
