Re: rca rear projection tv about ten years old
This problem is a hard one to diagnose as it could be 1 or a combination of things . It could be a bad solder connection or a power supply problem or a horizontal =sweep problem . need more info man . BUT if your not a tech its highly advised to you that you seek a pro to assist you as theres very high voltage in these sets even when they are un plugged and off for a while. There are no used wserviceable parts inside this set. Good Luck

Yeah could be expensive if it isn't the lamp.
Mind you could be a little easier, might just be a fuse on the video relay. If you are confident in being able to open it up, check the relay that runs from the video input to the power capacitors and there should be a small fuse along that circuit.
If the fuse has a broken capsule then you may just be in luck. Failing finding a broken fuse, then I would agree with you on the bulb. But check the blub for any markings or cracks because they usually only make noise when the vacuum fails.
Hope this helps and good luck mate! :D
The first place to start is the outlet and check to be sure it has power. The next is to check / replace the main internal (to the tv) fuse - it's a 5A 250V GMA fuse (google image of GMA fuse). To find the fuse, unplug the set and remove the back cover of the TV - follow the power cord to where it enters - the fuse is located to the right and slightly ahead of where the power cord is attached to the board.
