Hitachi 50v500 rear projection hd 720p big screen tv has a red spot in it. Anyone know what this is?
Hey, I bought a hitachi 50v500 projection tv with special lamps. The tv works fine but there is a huge red spot that takes up about 30% of the screen. I have consulted ebay professionals and have gotten mixed answers, so I do not really know whats wrong with my tv. This was the flagship model about 4 or 5 years ago and it is high def 720p. I did purchase this tv about 4 years ago and i have never changed the lamp or bulb, so it does appear like the picture has faded over time. I have a westinghouse that was quite a bit cheaper and newer and it is simply amazing, its a 32 inch and is so clear it can almost be high def in itself without it being actually in high def. I hope I didnt spend$3000 for nothing, cuz right now my $700 tv looks better than the $3,000 one.

It sounds like you need to replace the bulb. Make sure to buy the correct bulb for your TV. There should be instructions in the TV’s manual on how to replace the bulb.
It’s not the bulb. I had the same problem with this TV. The “light engine” needs to be replaced. The early light engines in these TVs didn’t allow for adequate ventilation. The result is that, over time, the LCD burns up. The red spot you are seeing is where the LCD has been burned. Unfortunately, the light engine will probably cost you more than a new TV at this point.
It’s not the bulb. The same thing happened with my set. The red blob means your TV needs a new light engine. You’re seeing the red spot because the LCD panels have burned due to inadequate ventilation. It’s a design flaw in the original light engines used in these TVs – not anything you did. At this point, replacing the light engine would likely cost more than buying a new TV, although you could try calling Hitachi.
