I have a 60 inch rear projection RCA TV. It has a chassis number of PTK195AC and is model P60812BL.
The day before yesterday it was working perfectly (as it has for 8 years). All of a sudden I walked into the room and it is black. Turning it off, using the DVD and many other attempts to get a picture failed.
I let it stay off for a while, then turned it on. It would have a picture for a short time that looked like an old 60's horizontal hold problem with a partial, shrunken picture. I would suspect some sort of voltage problem. I have not had a TV problem in 30 years. I have not called a TV repair man in memory. I have the user's manual AND a service manual because I thought it would come in handy some day.
I called a TV repair fellow and he said he was familiar with this model of RCA and that the typical repair bill was $250. I am pretty handy with this type of thing (and an electrical engineer), so I thought that before he came over and found that it was a simple thing like a fuse, I would try to look at it myself.
Anyone have any ideas where to start?
