I have a baird x47dtv and we turned it on today but had no picture or sound. the blue power light comes on and flickers as it should on startup of tv,however we are still not recieving a picture. i have replaced the psu's approx 6 months ago so i know theres no problems there,but am unsure which part i need to replace as it could be 1 of three things. 1 it could be the main board, 2 it could be the power invertors or 3 the screen. any tips would be helpful

My JVC HD56G786 rear projection tv is not powering on anymore. I have recently replaced the bulb (as I've done once in the past) and it worked fine for about 4 weeks. This weekend it began powering off on its own after being on for a couple hours and the blue and red lights would flash rapidly simultaneously. Now it won't power on at all- it begins to power up and then immediately shuts down and the lights blink rapidly. The bulb appears fine, but the owners manual says that this issue arise

Hello! I'm having the infamous black screen issue with my Viewsonic N3252W. I initially replaced the Power supply, because that looked like it was "the fix" for this particular issue.

I have a Sanyo 42 inch Mode Number: DP42647. I bought it 2.5 years ago, and suddenly, the video is out. The sound is ok, as well as the "power" green LED. By looking at other forums, it seems every Sanyo TV purchased in 2008-2009 has the same problem. Some owners report having their units taken to a technician, and their response is the "main" board failed. The main board in my TV is: N4VE MAN. I can remove it, and buy it online. Should I be worried about having more failed components?.
