Hi there

this is not meant as a solution, but a tip if you`d like to get an answer.
You should clarify in which occasion you get either sound and no video or black screen with sound.
This is a little confusing for a repairman.

Is the TV turns on and off cycles all the time? Sounds like something wrong with the main board.

The panel is defective.

Power supply board is dead.Replaced the power supply board well solved this problems.

After checking DVD and other accesaries (functioning OK), I turned the power off for the Cable Box and restart to reset the Cable Box which resored the VIDEO function. I recommend the same procedure for those who has a Cable Box.

Hi,

Sounds like there is a short on the power board or the power board has gone faulty.

Look on the power board to see if any of the capacitors are bulged or if there are any other components burnt out. The TV is going into protect mode because of an over current, which points to a short on the board or a component has gone short circuit.
Thanks

I know this is old bu does it still do this?

Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.
Replacement boards can be found at a good price at Shopjimmy.com

Hi,

There are a number reasons why this might happen:

• The backlight has gone (Find a dark place and shine a torch into the screen and see if you can see an image in the background, if you see an image then the backlight has gone) - Needs a new backlight (Engineer to remove and fit) or have a new panel fitted.
• The panel has died - Need a new panel
• A cable has worked itself loose or is broken
• The inverter has gone - Need new inverter
• The driver board is faulty

Thanks

This usually means the lamp or the ballast that powers the lamp is bad.

Could be anything! From a main board to a power supply. I recommend getting service on it from a authorized sony service center. If standby light doesn't appear at all for any given time, then it maybe the power supply.

If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV.
I will forward a link to a page where you can get more information and troubleshooting steps for this issue.

Please perform the steps provided on the page. If the issue still persists then service of the TV is required.

it is your HD box. get another one.

I have a Sony Bravia KDL 40S 2000 (lcd tv - mfg 06') The power goes into standby which I know could be several things but my question is this....I'm into the set only $100 so far. Is there some pointers you can tell me to look for with the once I remove the case for a visual look see? I don't want to invest another $100 to find out it's a $400 fix....any info would be great b4 I chuck it. (FYI-I am mech. inclined so I wont use info like an idiot.) Thx - Dan Rathburn

edit your inputs and make sure itv1 has't been put on skip


your channel 4 could have been automatically deleted if you did an auto program on the channels.
Poke around in the menu and you should be able to tell it to display channel 4

Question edited for clarity. Full 'make model (what it is)'. Question moved from Computers to Sony Bravia Television. Sony says is it the same television, just with a larger screen https://www.google.com/search?q=32ex650+vs+40ex650 You could ask Jimmy which is where your parts come from https://www.shopjimmy.com/

https://www.sony.com > support > res > manuals PDF You can switch between the i-Manual screen and the TV screen. This feature allows you to refer to the instructions in the i-Manual while using your BRAVIA TV.

Unplug the TV for a while and hopefully, that should reset the circuity. If you're using the original remote control, check for the display button and press it. I would also suggest doing a factory reset if your TV has that feature and if the TV allows you to do it after unplugging it.

The front and back pieces are like a clam shell and are compression fit with tabs into one another. You need to use something like a guitar pick or spudger to separate the pieces. Dont use metal objects due to damage that will happen to the plastic .
