Having problems with your Flat Panel Televisions ?

Hi I have a power problem, with my Sony RDR-HX717 DVD Recorder. I have no power at all in the display or anywhere else in my recorder. I suspect it could be the fuse, on the power supply board, which is a Newton Power NPS-51AP. The fuse is a T4AH-250V. My question is - what is the best way to replace this fuse, as it is in a closed fuse socket, which is not easy to open? Thx for any help. Fritz Diedrichsen

After reading several forums when my LG 42PC3D died, I went in thinking I had the answer. It would turn on, but then off immediately. The Y-sus board had a blown fuse. I didn't want to risk frying anything else, so I replaced the board rather than just replacing the fuse. When I disconnected the board, it would turn on and stay on. Now, with the new board, it powers up as soon as I plug it in (doesn't actually turn on, just powers up) but won't do anything. The screen is backlit with just

How do I find the power board in a 1997 big screen Sony TV to check the fuse? How do I check the fuse? I live in a house built in the 1890's, and last year there were 2 different tornados ,within 2 weeks of each other, that blew over trees on top of my power line twice in 1 month.

My Vizio P42 plasma has no picture but has sound. I removed the back panel and removed fuse FS1 on the Y sys board as well as fuses FS1 & FS2 on the Z sys board and they passed the continuity test. I also did continuity on surface mount fuse FS3 on the Y sys board without removing it from the board and continuity was ok and the same with FS3 on the Z sus board. I know that testing a fuse on the board is not the best way but it seems that it is the only way to do it on the surface mount fuses.
