It won't power up. The power light will just pulse on and off. With the cover off the back I can see a few green LED's on the circuit board pulsing on and off too.


The problem is a blown capacitor and a pico fuse. You can get complete parts and instructiosn for this fix from TvRepairKits.com. They put together a kit for this. I used them for a convergence problem recently and they helped me fix my set.

High pitch pulsing & picture now


I would check the set for bad connections. The high pitched sound you are hearing is the high voltage section. If the convergence IC has completely failed, that can cause this as well. Try using STK392-150 or STK392-180. Either one will sub since they are pin compatible and they both can handle more power, thus should last longer. Also, make sure that you use plenty of the heatsink compound when mounting these.

Remote not working for TV


If the batteries are good try this:
If you have a video camera, set it to record, then point the remote at the video camera and see if you can see the lights blinking at the end of the remote. (The video camera can see the infrared light pulses emitted by the remote even though your eyes can't). If you see pulses then your remote is working. If not the your remote is broken.
