These sets have weak picture tubes, this may buy you some time. It is not worth changing the tubes in the set. The cost would be more then its worth. Try these adjustments until it completely dies. I have the same set.

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN.
