The relay is in the power supply area. I am sure that the fault is not the relay.

It is very common that there are various components starting to go off spec from age. Most of the failures are in the scan amplifiers and power supply areas.

It is also possible that the CRT emission is too low from age. What happens is that it is on the minimum edge and this explains why the set may turn on some of the time.

When the main uPC in the set sees any potential fault conditions it will go in to a protection mode to prevent damage and to be safe. Your set is probably borderline to operate.

Considering the age of your set, I would be shopping for a new TV set.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.
