HiCustomer Thank you for asking your question on JustAnswer. The other Experts and I are working on your answer. By the way, it would help us to know:


-Could you explain your situation a little more?

 

Can you confirm the model number of the TV? The model number will be displayed on a tag on the back of the TV near where the power cord is attached.

How long have you owned the TV?

Thank you again for trusting us with your problem.

 

Please reply as soon as possible so that we can finish answering your question.

The Model Number is XXXXX#ABA. I purchased the TV a little over two years ago. I tried to turn it on today when I got home, and the power light in front flashes, it seems like the tv is shutting itself off and on, but no picture or sound.
Expert:  Edward replied 5 years ago.

Heat is the enemy of electronics, and the EX543AA operates 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. The EX543AA 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.

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?

If you decide this is not something that you can do I expect this repair will be about $150 to $350, 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. A small TV repair shop will often charge less for the repair than a large electronics repair facility.
