Undo the back and see if the fuses are blown. Replace them if they are.

The screen went blank and green light started flashing. Turned off the TV and let it cool. Turned it back on, getting sound but no picture. Red light is on, after about 15 seconds the green light blinks...


Since you say that there is sound but no picture, the first thing I would check would be the status of the lamp. I believe that the lamp has been shattered or the filament is blown. Please verify this and let me know

Picture goes out and red power light flashes


Up , i also encountered the same problem 3 days ago. 42" Fujitsu Plasmavission. I'll try to call an expert, i hope its not a digital board again for me, it will cost around $2,000usd so better buy a new Korean made LCD for better and cheaper parts. I guess you also experiencing trmendous heat at the back of your plasma right?

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

Plasma wnt stay on


I have had this problem in some models of plasma sets before. In most cases the power supply and main drive boards had to be replaced. In a small number of cases the failure was the screen itself.

In all cases, the cost of the repair was expensive. For the screen failure, the set was scrapped.
