Inspect the power and deflection board for hot spots,areas on the pcb that have been discolored (dark brown)due to heat caused by cold solder joints which in turn will cause the circuit to draw more amperage resulting in even more heat.Heat is the main culprit of component failure in all electronics.If you find any hot spots,inspect the area right underneath it on the solder side of the board and look for loose solder connections or solder that appears to be desintegrating or breaking down(eroding),if you do you will need to resolder the connections,you will need a soldering iron and a roll of solder to do the job.If that is not the case then replace the power supply module\board.Good Luck

Burn spot and sparks

is it a off white block with a pink wire set going to the 3 picture tubes?then it is the high voltage called a flyback transformer.
the output is 28000 have to discharge the tubes before replacing the anode caps which are connected to the flyback.
this is a severe shock danger.
do not attempt this without the service manual ,about 35 dollars from rca.

Burnt spot on board

Depending on what caused the burn spot. It is possible to solder a bridge or jump wire from the point on the board that is not damaged and follow the trace or film connection to the next point that is to connect the two points. Other wise find a solder point on one side of the burn and if you can follow the path to the next solder point, use a jumper wire and solder each connection bridging over the burn. Wire has to be insulated. Some burn spots are caused by poor factory dipping of the board, and the solder loses connection over time from heat etc.

Good Day, cs81801;
It sounds like the TV's Convergence Circuit has failed.First, try
to reset TV by unplugging TV from A/C source, for 2 to 5 minutes. Then plug TV back into outlet. Also, try the Magic Focus button on front of TV.
Still no work? To fix yourself call 1-800-458-6053 and ask for KIT 10. This will provide you with all the parts you will need. These are soldered in parts, or call an Authorized Service Center and have them give you a written estimate b4 repairs are performed. Cost? between $450 to 650 depending on your location and Service Center. Good Luck, big IRISH.

Picture flickers when T.V. is tapped on or struck.

sounds very much like a loose connection, i.e. a wire or solder joint, you could have a look around make sure everything is plugged in right, as for the solder joints id advise getting it proffessionally looked at as these rear projection tvs can be a lot of hassle if you slighty knock any of the 3 tubes,
