Question about RCA 20F512T 20" TV
The problem is with the power circuit board components . The capacitors
have gone bad. A pop sound is created due to the burn out of the
capacitors..Faulty capacitors can be identified either by using an
continuity tester or by appearance that i will be bulged at the top...
Most probably the burned out part which created the pop sound must have created a burned appearance in that area. Just check it out...
If you are an novice in working with the circuit board please take it to a technician who will be able to desolder the components and solder it again..
