You will need to replace the "D" board in the TV or have it rebuilt. This is a very common issue with these Sony TV's. This is the part number you will need A-1346-948-A

Hello
Your problem is not the power button as the relay clicks when pushed.

LCD PLASMA or REGULAR
Then I will be able to tell you more.

    It sounds like a (switch mode) power supply problem.

    as it is critical on startup

    This is one where you will have to have a tec. look at it.

    Thanks Guy9

Do the same thing your brother did. try it. it is probably a dying switch, if it was the power supply then it would be dead already. if it was the logic circuit, then it wouldn't turn on at all. if the tube was gone, the set would click, but not turn on.

First of all, who is the tv made by, then what is model number ?
All this is important. Stop trying to turn on !!  Yes if could be switch assy, but if remote doesn't turn on eith, then you have a Power supply problem or logic.
You will need to find a local servicer. Check yellowbook and craigslist for tv repair.

You might have problem with the TV's power button. You may want to use the TV remote to turn it on/off or or get a coverter box from cable company like Comcast, and the cable remote can be program for it.

You need to check your inputs. Make sure your tv is set to the same input that you are plugged into. Ex. If you are plugged into HDMI 1 then your TV SOURCE needs to be on HDMI 1.

I have a lg 2540 soundbar connected to my 37inch lg tv. Soundbar works fine on all channels, with the exception of all the HD ones. My tv is connected to a Humax satellite box. Any ideas please.


Maybe the HD channels do not support showing the sound bar via a satellite box connection. Call the manufacturer of the box and inquire with them.

I have a problem with my sony trinitron. it doesn't have a picture when it's turned on. instead, i get the blinking timer/standby light. it may make a sound like it's coming on, but again, no picture. ...


The TV is in a "shut-down" mode to protect itself from further damage - there's probably a shorted transistor in the horizontal or vertical circuit. You won't be able to fix it yourself unless you know how to isolate the problem with a schematic.

No picture when vga cable is connected


Most tvs can only handle a couple resolutions (ie 640x480) through the pc input. Even some HD tvs can only do 480. Check that your video is turned on and setup to the acceptable resolutions.

right click your desktop
go to properties
click settings tab
click on the 2nd monitor
make sure the box is clicked at the bottom
