I would bet on some component(s) have become thermo sensitive. Most of the time capacitors can do this type of thing. Most likely the defective caps could be in the power supply.
To locate the defective caps, you would have to be able to run the supply and use the combination of a heat gun and freeze spray (liquid air spray) for cooling. At the same time you would have to monitor the output of the supply to see the components that cause the output change.
It is also possible to have thermo sensitive components on any of the other boards. This would also require proper troubleshooting.
The service rep would replace boards until he found the defective board. Then he would return the set with the new board and the bill for his work.
If your set is out of warranty, it may be better to consider a new set. Servicing these can be fairly involved and expensive.

If you were to log on to the
manufacturer's web site, I think you will be pleasantly surprised as
usually one is able to download, by model number, Customer
Instruction Manuals, list
of Dealers for spare part supplies and
Just Google the manufacturer's name and
follow the links. Make certain you are directed to the manufacturer's
web site as some search engines direct you to other sites and they
charge for the information that is normally free of charge.
I hope this helps.
