This generally indicates an issue with the backlight inverter loading the power supply. The inverter assembly is easily replaced in this panel and costs approx. $90-140 depending on your parts store. Please use caution when working with this component, it produces the very high voltages required to illuminate the screen.
Good luck to you.

SOURCE: Plasma TV will not turn on

The 7 blinks means that the SC scan drive board might need to be replace but only after checking the voltages from the power supply. If the voltages from the power supply are normal, then proceed to replace the SC scan board.

SOURCE: Panasonic TCP58S1 has no pic. or sound. Red light blinks 9 times.

It's dead. 9 Blinks means the display adaptor is dead. If it's still under warranty, you're covered.

Hello, i have a sanyo dp 19648 that was working perfectly when last used, i have been away on a trip & turned all electric power right off from the mains & when i got back, the tv will not come on...


Power supply in set has a standby the runs 7/24 (all sets do and computers also) and the loss of power when restored may have damaged something there---a fuse is possible and should be looked at first---the Standby provides voltage for the remote to turn main supply and the set on.

3 times standby red light blinking shows that lamp cover has not been placed back properly after lamp replacement.
Make sure lamp cover, (the first thing that you removed to replace lamp in tv) is fixed securely then turn tv On.

Green light blinks but TV will not come on...nothing


Could be the lamp has gone out. If this is a DLP the lamps are pretty easy to change and cost $130 to $200 dollars. Check the lamp before you toss it out.

Printer problem


Make sure you have full printer cartridges. If this does not work. Turn off the printer and unplug it. Then try to plug it back in and turn it on. This will probably make the problem go away.
