Tip & How-To about Televison & Video
Look for dried out thermal paste on the transistors / i.c.'s especially on the power supply board.
test while the set is on, carefully! using coolant spray (freon) and, a hairdryer to find heat related faults keep turning the set on and, off to replicate the problem as you heat and cool components until you find the offending component. the coolant is non-conductive and, will not harm anything it touches except you. wear safety glasses and, keep your hands out of the way of the spray nozzle.
remove old non-conducting, heat conducting paste if a component gets too hot and, re-apply the paste.(component heat sink cream)
radio shack sells the coolant spray (component cooler) and, the paste.
