thank you for give me chance to help you,

please give your ratings!

You have the following options: 1 Go to Sony web site. Under the support section go to accessories. Select your model and then order the stand. 2 You can go to your retailer or Sony dealer in your area and ask him to get you one. 3 You can buy it on lone from amazon.com, tvstands.com, best buy etc.

Try going into menu input set up on tv and switch to av input. Just a thought I have the same model and had exact problem. All I had to do was change input style to av cable.

I have had similar experiences. I have a VCR sitting near the television. I found that if I keep the VCR turned on then the TV stops changing channels by itself. If the VCR is turned off, then it starts again. Weird, but it worked for some reason.

Hi,
It seems problem of lcd panel (screen) of tv that will be replaced.
Please check warranty documents of tv for warranty validity, call Sony as number would be written on warranty papers for lcd panel replacement and if tv is out of warranty then lcd replacement would cost you more than new tv price.
Thanks.

Hello

Bravia KDL series are for use in US and its reception system is differnt to that of in India. Your TV can only accept signals of NTSC and ATSC. These are the statds of transmission used in US. In India, all transmisssion and recordigs standards ar of PAL. Your TV won't accept PAL system signals properly. Theese systems mentioned above anr the colour transmitting standards. You have to choose a multisystem compatable TV from there in US. There is no hopt for you to get PAL type transmission signals to recive with your tV. It can play NTSC recoreded dvds or Blu-rays or Video casette tapws, whatever it may be, properly. There is no chance to get it converted to a multisystem, or even for a PAL system converstion with your TV. The colour informatin will not be processed properly. OK.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

it will be more than the new 40" TV. LCD panel is limited production and the most expensive part of the TV. I would sell parts on EBAY and use the money toward new TV.

Outlet is OK?
Check the power supply module, connections, look for any blown parts, etc.

Hi there
Check all cables are connected properly, and then try resetting the picture settings in the TV's menu. Is it on all devices you are getting this, or just say the DVD/VCR?
Hope this helps
