When I hit the power button on my Toshiba 36AFX61 tv, or when I hit the power button on the tv's remote control, the tv's power switch button LED comes on but I get no picture or sound. And, the power button LED starts to blink after about 4 or 5 seconds. Also, at the time power is applied to the TV, I can hear extra relay contacts clicking that normally cannot be heard when the tv powers up correctly.

We had this TV gave to us. It is a magnavox 1988 big screen star picture in picture. Our problem is we have no picture no sound so we questioned them and they said its in sleep mode. How do we get it off if that's even our problem. We can hear the TV come on and power light comes on then we hear a click sound and the lights power sap and stereo lights are all on.
Unless you are lucky this set is beyond repair due to its age as most parts no longer exist for it, I actually have worked on a lot of those when they were fairly new-----Most common issue was broken or bad solder connections all over the set and age ...

I have a Sony Bravia kdl 32w5500 and it periodically switches itself off whilst watching programmes on one particular channel (WIN TV AUSTRALIA). It goes into a kind of sleep mode or something and sometimes also switches off completely. When it first loses picture, and sound, the green light is on and you can change channel and the picture and sound comes back but when you go back to WIN TV it again switches of picture and sound and eventually the whole set, if left on WIN TV. The remote channel

I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

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 60ux55k rear projection TV, and like other posts, it just "died". The power light comes on, but no picture or sound. I unplugged it as suggested, but still nothing. All the LED's on the board light green, except one which is red. Without an actual schematic, I am guessing it might be the surge protection circuit and has remained "stuck". Is there a non-expensive solution? Is there a way to obtain a better manual than what was supplied when purchased? Are there any detailed schematics a

I have a Vizio VW32LHDTV10A that produces sound but no picture. I have checked the main power board for 24v to both backlight inverters and 24v is present. I then hooked up both backlight inverters and turned the TV on and the blue LED on the Slave inverter comes on, but goes off after only a few seconds. What further tests could I perform to check which part is defective or what component is the most likely cause?
When you reconnect the inverter boards, when the LED goes off on the inverter board, do you still see 24vdc? You shuld also ty hooking up test lamps to the 24vdc to see if it will stay on.\012Right now I have a feeling the problems are in the b ...

My tv works OK except after switching on it takes 30 minutes before a picture arrives e.g. the green light flashes for 30 minutes before the picture comes on. Sometimes when the picture does arrive there is no sound but that is easily fixed by switching the set off and on when picture and sound are restored immediately. Any ideas what repair is required and what it would cost?
There are two most common causes of this problem, and it's accross the board for all types of TVs: faulty electrolytic capacitors in the power board or BGA processor solder failure on the main board.\012\012Of course there are other possi ...

I have LG LCD TV Model No: 22LF12R. The problem is the TV fell face down when it was still powered ON. Now when you switch it on the power LED comes on but there is nothing on the screen. When you press the remote control the LED responds or it blinks and when you power off on the remote it goes off and when you power on it comes on. The problem now is there is no display on the screen. There is no voltage in the display unit. Which components shoul I change. Hope u reply soon.
In my experience, there will be damage to the main pcboard, usually under the transformer.If you are lucky you can find all of the broken track and remake the track.Good luck. ...
