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

I have a Sharp LC42D62u that has sound but not picture. I have done the flashlight test and can see images. I replaced the both master and slave backlight invertor boards, but still no picture. There are capacitors very close to the connection site from psb to invertor board. Could these be the problem? Any suggestion?

I have a Pioneer PDP-4340 plasma TV. I was watching the football game when I decided to go to the menu button and see if I could adjust the color contrast. Although it tells me I cannot perform that operation (why?) I continued to scroll thru all the categories: e.g., sound, audio, etc., etc. To my knowledge I did not change any settings, just keep pushing the menu button to come in and out of the selections. All of a sudden I lost my picture but the sound still came through. I shut down t

I have 50 inches plasma Hitachi TV (ALiS 1080HD). As the TV was on, the screen stopped showing (no picture) and no sound could be listened as well, without any reason. The power light started flashing (on and off) so I turned the TV off from the power supply (as the remote control was not responding). Few seconds later when I turned the power supply back on for a moment I heard a sound (making me believe that the problem was fixed) but once again the power light started flashing with the same en

Samsung ln40a530 Hello, I repaired the power supply on that TV. I changed four capacitor 10v 1000UF and 25v 1000UF and a small chip on the pcb QM806 (4894B: SI4894BDY equivalent) Now I have a good read on all output.
Thank you for the help found here!
But now I found a ground on the main board. 5volt is on the ground(short). I unsoldered some chip without result, the 5v is still on the ground.
Could someone tell me what the problem might be?

Hello. My tv will not turn on. I metered the power circuit as far as I could, and it looks ok. The fuse on the control board is good. The power switch meters good. When the tv failed I heard a small popping sound, but did not smell any smoke from a damaged component. I cannot tell if the problem is with the control board, or with the picture tube. Thanks
It sounds that the power supply regulator section or main board has the fault. Check it with the help of schematics. If you are not handy, seek any technician's support. ...

Lg263000 my lg263000 tv is showing a white screen, although the sound is fine, i believe it to be the tcon board. could someone tell me what the tcon board looks like...thanks
It could be a bad T-con, but it could also be a faulty LVDS (cable that connects the t-con to the main board), or you can have a main board fault. It sounds like your panel isn't getting power. The T-con board should be located top center on the back ...
