TV Repair Questions? Ask a TV Technician
Thank you for asking your question on JustAnswer. Heat is the enemy of electronics, and these sets operate hot. You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. 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. 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? Do you own and know how to operate an oscilloscope? Should you require further clarification, never hesitate to ask.

Thanks for the reply. I did ask," Do you wish to repair this yourself or are you looking for an idea of what the cost to repair the TV will be?" The blink codes are provided to the electronic technician as a starting point to start looking for problems. They do not tell exactly what will be needed to repair the TV. This requires testing. Had you indicated that you wanted to repair the TV yourself and had the needed test equipment needed to diagnose the circuitry I would have asked you about the number of flashes that the TV was displaying. Since you have determined that you will need to send the TV out for repair, I will ask for this question to be closed. If you have additional questions I will be glad to answer them.
There is no need to reply to this post unless you have additional questions. It will only generate a request for me to reply to your post. Regards,Edward
