Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Go into menu on the tv and look for start up setting and look for tv ratio and change it. The cables should be right. The wii will not change aspect if the tv is not compatable

i had prob where my sony would switch off for a few secs thenh come back on . The solution was in menu / tv settings / sleep timer . Go into that and make sure its set to off. there are opions for off , 5 min 20 min 30 min etc... mine was set to nothing just blank.

if the standby light blinks 6 times it has a bad backlite board (the most common with that set) other than that i will need to know how many times in a row it blinks. thanks....techman

Hate to give you some bad news...But most likely you have a defective screen. You may be lucky and just have a bad T-con board. Which will do the same thing. But, this is a slim chance of it being the issue. As I have had many of these with bad screens. And only 2 were the T-con board which the color was off and pict was darker than normal. It is the board at the top center of the TV.

Try a new or known to be good cable. Try attaching to a different computer. Prove the monitor will work first.

Power board in side the tv needs to be repair or replaced

Hi,
To reset the tv to factory/ default settings, please follow below procedure.
Turn On the TV, while holding down Up Arrow on the remote control, press Power button on TV, tv will turn itself Off then back On again, release Up Arrow on remote control.
This procedure will reset all settings in tv to default settings.
Problem seems with lcd panel and I'm afraid it does not seems to get solved by resetting tv however try to reset tv by above said procedure.
Thanks.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).
