Bad electrolytics in the screen supply?
Faulty B+ regulation?
Unless you open er up and do some technical troubleshooting with test
equipment at your end all you will get is wild guesses.
You should get it to a shop right away to get it fixed... if you nurse
this along, the problem may get worse to the point that more expensive
parts will fail and it won't work at all, thus a much more expensive
repair.
At the very least, take it to a shop for a repair cost estimate so you
can make an intelligent repair decision with facts instead of guesses.
