UPDATE: Magnavox TV MS3252S431 Won't Turn On
Hi,
I ordered a Sams Photofact #4968 for this model TV. With the aid of a schematic, I was able to track down the problem to C2455 47UF 25V 85 deg capacitor in the horizonal drive circuit. This capacitor measured around 8UF (very low). I replaced it with a 105 deg type. Brad My original post: I have a Magnavox TV model MS3252S431 ch L01-1UAC-7638 (mfg Jan 2004) in my shop. It won't turn on. Fuse ok. Reg B+ is 128V after power button pressed. H.O.T. is not shorted and there is horizontal drive (apx 3V P-P) at the base of H.O.T. for a short period after the power button is pressed. There is continuity between B+ and collector of H.O.T. Note: I have no SM. Thanks in advance, Brad Before you type your password, credit card number, etc., be sure there is no active key logger (spyware) in your PC. |
