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
It may be a fan or a power supply issue, as you said.If there is a fan or other cooling device near the bulb, make sure it is operating. If it is not operating, replace it and see if it works. If it is a fan problem, you will notice becau ...

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 powered it on, and I was getting the same problem. There was a faint picture (you need to look at the screen from a certain angle, with an appropriate amount of light shining on the screen.) with no back light! All of the voltages coming off the new PSU are right where they should be, including the 24VDC to the

The Timer indicator on the front of the TV is continuously blinking green. I have made several attempts to fix this by pressing the System Reset button and held it for up to 30 seconds at a time. Each time I release the System Reset button, a few seconds later the Timer indicator starts flashing again. I have also totally disconnected the TV from power for up to 15 minutes but as soon as I connect it back to power the Timer light starts flashing again.

Samsung PS-42Q96HD Hi
My Samsung PS-42Q96HD went dead one day no pic and no sound- so I opened up the back and on the psu I replaced 2 bulging capacitors.
Now the tv comes on with sound but with no picture. As far as I can tell there is power going through the X and Y boards and the logic board has 2 green led lights on.
Any ideas would be greatly appreciated.
Thanks in advance
Please check whether the inverter is working and giving voltage to the display board. If not, this might require attention of a qualified service technician. ...

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?.
