Question about Philips TP3681C 36" TV
Techman responded to another post stating that it probably was not the picture tube. He asked for more info. Since I have the same problem for the same TV and it definitly is not the TV power cord or the socket, etc. I thought I would give you : The chassis number: 36D7007570 The model number: TP3682C101 The serial number: 14430134 My son says that he can here a high pitch noise when the TV is plugged in. He can hear it, but I cannot! When the TV is plugged in, the back does not get warm. Is there anything else you need? Please let me know if you can help. Thank you.
A high pitched whine is most of the time the power supply trying to run, but it is being loaded down from a short somewheres in the set. Sometimes a resistor on the CRT board will open and make the set shut down right after start up, sometimes the horizontal output transistor causes this problem, almost any circuit for that matter can cause this problem. Good Luck
