Question about Samsung TX-P3264 32" TV
TV does not power on. Red light on power button blinks but screen remains blank. Also, TV emits high-pitched whine. I suspect the flyback transformer is causing the problem. However, someone told me to also replace the horizontal transistor. I don't know where to find this component inside the TV. Is it near the flyback? If anyone could please confirm my problem and tell me where the transistor is located that would be awesome. If anyone has a schematic or service manual of any kind that would be great too.

The HOT Hortz output transistor has gone home, 99% of the time from a faulty IVHT (Flyback Transformer), very common on the ctc187cl* chassis. The factory Flyback is no longer available, I have had problems finding an aftermarket one to replace it with.
The HOT is a BUH517, but you can also use a 2SD5129. It is the transistor mounted on the siler heat sink with a metal clip rather than a screw, just in front of the flyback.....
If you replace just the HOT, most of the time you will get a rapid arc (27,000volts - BE CAREFUL!!!) from the lower (yoke) post on the flyback. If the flyback is shorted, It may also just burn out the HOT and go right back to "squealing"....
Good luck finding the flyback!!!
