Sony KDP51WS550-LED light blinks 10 times

This is usually a problem on the high voltage board. When you first turn it on, the main board does it's P.O.S.T., then powers the HV board. You'll be hard pressed to find a replacement for it. You MIGHT find someone that can rebuild it, but for the money? Time for an open box special at you local electronics place.

Gateway GTW-P42M102, first sparks, now flashing green lt. in back

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Gateway GWT-P42M303 screen problem

the 15v is shorted to the ysus board and probably one of the two big heat sinks with the number 4921QP1002B is the cause. If you don't repair it can I have it for parts?

Gateway plasma tv

I was able to resolder the pin shown in the picture and it fixed my problem as well.  I also used a razor and cut off the last socket for that pin on the connector and put a dedicated connector on so that it will take the heat a little better.  Also when I re-soldered that pin on the bottom side of the board I scraped away some of the protective coating around the solder puddle so that I could make a bigger solder puddle to add a little more strength and heat resistance.

How do I remove the back cover from my flatscreen plasma TV?

Cover a table protective blanket. Place TV face down on table. Remove the stands legs( 2 screws each) then 4 large screws the legs attach to. Or remove the wall mount brackets. 2 small black screws middle of the cover (above the component interface box). Remove the component interface box, 5 small black screws , 2 on top, 3 on bottom. 6 black screws by the PC connection ports, (3 above, 3 below). 2 black screws on either side of the AC input plug. 12 screws around the perimeter. Then the back should be able to be lifted straight up.
