Have TV Questions? Ask a TV Technician
Thank you for asking your question on JustAnswer. First I will recommend unplugging the TV for an hour or more. This may correct the problem if it is not component failure related. Please be careful if you open the TV. The manufacture recommends that there are no user serviceable parts inside. This is due to high voltage being present even with the TV unplugged. The problem is very likely a power supply issue a problem this TV is known for. I will never reccomend replacing any part that is not verified to be defective and that the other circuitry in the TV is verified not to have been the cause of the part to fail. These sets are assembled using the wave soldering process they are known for having cold solder connections. This model of TV has over 2,000 parts which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad. This may 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 if the parts that caused the failure to begin with are not replaced. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service 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 or a way to tell what is wrong with the TV without testing the circuitry, but that is not the case or the solution needed to get the TV operating correctly. Do you wish to repair this yourself or are you looking for an idea of what the cost to repair the TV will be?
If you wish to repair it yourself what type of electronic training do you have?
What type of TV test equipment do you own?Should you require further clarification, never hesitate to ask. It would be my pleasure to clarify my answer to your question.
