I just replaced the bulb last week, yet this time the TV will still not turn on and all three lights are still blinking.


It is possible that the replacement lamp is bad but more likely the TV has a protection mode that triggers wen the lamp goes out. Check the manual for ways to reset the lamp usage back to zero or a function that needs to be manually reset when the lamp is changed.

My Zenith plasma TV blinks green 4 times then goes red, No picture. None of the Capasitors are blown.


I had AWFUL customer service. (Sherry is DREADFUL her # is 1-877-543-8325 she is in"executive services". Ask to speak to her directly...if you would like ZERO help.)

They WILL NOT extend the warranty, even though they know there is a defect with this AND other models. Zenith name on the front...LG guts in the inside.
Ours turns on, screen black and then clicks three times and then turns back off.

Sony vega tv turns off after 10 minutes and a red light blinks three times


to check well how many times blinks.
2 times - to mean overcurrent
4 times - vertical deflection stopped
5 times - white balance failure.
any way I think that is an soldering fail in the board.

WS-55517 Mitsubishi Rear HDTV projection tv will not turn on


2 blinks followed by 1 blink is the X-Ray protection-----means some problem in the High voltage circuit ---set produces over 25 thousand volts to fire the 3 picture tubes inside up----It could be excessive high voltage-------I think you would have to get lucky for someone to find and fix it in your home----more likely it will need a visit to a Repair shop.
