Thank you for asking your question on JustAnswer. This is a CRT TV and has no lamp to burn out however it does have 3 CRT that can go bad. These sets are assembled using the wave soldering process they are known for having cold solder connections. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly. I expect this repair will be about $350 to $550+, depending on how many parts are found to be out of factory specifications, if the problem is a bad circuit board, and if the board can be repaired or has to be replaced. Once repaired the TV is likely to fail again. Many consumers are replacing such TV with the large screen LCD HDTV. The picture will be as good or better, the set will take up less room and cost less to operate.
