    I have a Hitachi 50V500 Last year I replaced the light engine and now it has developed a small green dot in the middle of the screen. Is the engine going bad again or is it something else?

Hi Mirna,
This problem is due to loose contacts in the LCD panel in your TV. To fix this, the TV has to go to Panel repairing machine (tab bonding machine). I hope it helps.
Good Luck.

Blue dots on LCD screen, Sony tv.

You probably need a new optic block. The part alone is approx. $900.00. Sony has had this issue with most of their rear projection LCD televisions. Sony was offering to either repair the tv or give you a substantial credit [$1100.00 or so] towards the purchase of a new Sony LCD flat screen but I believe this program ended in December of 2008. You may still be able to call Sony customer service and plead your case. Good luck!!

Green dots on screen

Green dots on a LCD screen are burnt out pixels and unfortunately are incurable other than having the TV serviced at a high price. One of the reasons it is a good idea to get a warranty on these types of TVs is primarily due to this very problem....burnt out pixels.

Green and Blue spots on screen

Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.
