Couple of months ago my tv started giving problems. don't remember exact symtoms. Took it to a repair shop in my area but guy said he could not repair as part cannot be found. It has been sitting down for a while and I decided to take it apart and see what might be the problem. After all I don't think I can make it much worse than it already is. I am not a tv repair guy but I do know how to solder and have minor knowledge of electronics. Any way I took the tv apart and checked the board I noticed that transistors # 7461, 7463 , diodes #6460, 6461 and resistors 3477 and 3478 have burn marks on the board. TV powers on but there is no pic or sound. I also noticed that the repair guy removed and replaced transistor # 7460 but there is no burn marks on that immediate part of the board. I fgured out that the resistors are both 150 ohms but can anyone tell me the part numbers for the transistors so I can try to buy and replace them. Thanks |

Good old NAP. Replace C2455 47@25V. Other most common is the HOT shorts in this one. |
