With any type of service, if you do not know the basics you should not be trying to do the service. There are also many safety issues when working a TV set or any appliance that uses high voltage supplies. To follow up for any testing and measurements you will need the service manual, and most likey some dedicated test equipment, and depending on the model you may need the exension jiggs.

The first section to be verified is the power supply, and then verify the loading of the other boards. At the factory level service, the power supply module is swapped out to quickly verify it especialy when the set is dead. The the other boards are swapped out as necessary for verification.

The flat panel type TV sets are mostly serviced by board swap. There is very little component level service support for these. All the boards are using high density circuit board design in multiple layers. Only some of the large caps, switches, and a few other descrete components are changed on a board or panel.

Power-On Problem on a 46" Sceptre Flat Panel


The high voltage spike damaged electronic components inside your tv. Transistors and microchips are very sensitive to high voltage spikes even if they last for a fraction of a second. It can probably be repaired by a tv repair person but if the tv is several years old, it would be better to just buy a new tv. The cost for a new tv is much lower now than it was just a few years ago.

LG M227WDP turns black a couple of seconds


Do you have the "sleep" mode turned off on the computer?
As well, you can try different screen resolutions and refresh rate settings on the video section of your computer. That might make the connection to the TV more stable.

10 red blinking lights on my Panasonic Plasma TV, will pause for few seconds, then blinks again. TV will not power on.


This is a power supply issue - found a company that has used power supplies, they sell them for $60.00. We recommend a professional install the board because the voltage needs to be adjusted after the install or you could damage something else. The high voltage in the set can KILL you soe be very careful. The web address for the PS board is plasmafix.com.
