 |
|
| I have an RCA Model # F32648 that is a few years old that stopped working after just a few years. It has been sitting and I would like to try to fix it my self. When I turn it on it jus puts off a high pitch squeal. I can not turn it on or off (the screen stays black so I don't know if it is on or off) Any sugestions? |

| The squeal is fro the horizontal out put transistor 2SD5148 the transistor on the heat sink by the flyback Q4401 I'd replace the flyback also. |

| It' a 2SD5148. Check Q4401 (2SD51480) to see if it's shorted. Also resolder L14401. |
