Check the connection sockets. If you haven't connected the flat cable, that connect to panel board is not in the proper way, this could happen. As you reported here, when you taken out the panel board out, and switched it ON, it has worked; means, the set have no other fault. Ask your father to check this. He can understand it. Check for any minute breaks in the PCB [ control panel] too. http://electronicshelponline.blogspot.com/
here ya go this video will show you how to do that,while the cabinet looks slightly different because this is a older model the process to replace the belt as far as how it goes on drum and motor is exactly the same http://www.youtube.com/watch?v=6ufArteqWXk
I SUGGEST CLEANING THE LENS ASSEMBLY. IF YOU LOOK ON THE SIDE OF THE TV CABINET YOU WILL A SMALL SQUARE THAT IS ABOUT 4 INCHES BY 6 INCHES HELD IN WITH ONE SCREW IF YOU LOOSEN THAT SCREW YOU WILL BE ABLE TO GET INTO THE CABINET OF THE TV AND CLEAN THE LENS GOOD LUCK
To do it correctly you will need a Scope so that you can see when the Audio equals the RF Transmit power if it is Less it is not efficient. If it is more it is Over Modulating and splattering and not giving you intelligible transmitted signals. The best way is to get an old copy of the Radio Amateurs Handbook from the late 50s to the early 60s they have a circuit you can build to watch Modulation on an FR Carrier that will do exactly what you want.
If TV goes off and the led stays blinking, that is because the TV is going on protection. Protection is a special diagnostic mode that starts when an internal fault has been detected. If this happens erratically while you are watching TV, then parts that can commonly cause the problem are PSU board, main board or digital board, ballast board and converge board on DLP, inverter on LCD, low buffer and sustain boards on plasma.
