I have no power after an electrical storm. Is there a fuse to prtoct the power supply from a power surge or did it fry my power supply? Also the cable conector got ripped out when someone tried to move the tv, looks like the board is broken also. Any suggestion?
You will need to replace it. The storm fried your board for sure, there is no fix for that, and a broken board is useless. you can't really put it back together because the entire surface of an electornics board is conducting electricity through it from component to component. If it could be fixed, it will surely cost you more to fix than buy a new one. Sorry to be the bad news bearer but it is shot, you are left with a giant paperweight.

Try this: unplug the set and wait about 10 or 20 minutes. This is to make sure that the main power supply filter caps completely discharge. Look on the power supply board, close to where the AC cord attaches to the board. Look for a white resistor labeled "0.1 OHM" (the symbol for OHM, like an upside-down U) and measure it with your ohm meter. If it is open then your switching transistors in the main power supply are most certainly shorted. Older sets had 2 separate transistors on little heat sinks labeled "C4834", then they switched to 2 transistors in one package labeled "MX0841" or "MX0842", and then some sets went to two separate MOSFET transistors. Measure those parts and post your results and we will guide you from there.

Do you have a VOM meter? Unplug the set and open the back, the fuse should be easy to find "small glass cylinder with a metel cap on each end. Test it for continuity. If it tests good or shorts again after replaceing then there is a lot of other things that can be wrong. Let us know. If you replace it it is important to use the same exact value which should be written on the board next to it also NEVER jump it with a wire! Hope this helps. Don

Hi
first all you have to do is to check all section in power board! check the wire,fuse, then check the power board section. maybe you have burn regulator!.
Thanks!

Hi,
You can download service manual of KV-36FS200 free copy from HERE that will help you to repair tv problem.
Thanks.
