Hello: I have a sony kv27s20 tv and suddenly after a rain lightning thunder it went black. It was turned off but the TV was connected to the electrical outlet so the stand by mode was on. After that the TV is not turning on, stay black.
I took it to the technnical service and they told me that the best way to repair it is replace the main board ( A board I guess ).
I am looking a store where to purchase this part. Actually I do not have the part number so If anyone around know the part number I appreciate if it can mail it to me.
Any other idea about this problem will be helpful.
Thanks in advance

Is easy for them to say replace the main board,it will cost as much as a new tv or close,they say that because of the damage lighting or power surge causes and is unrepairable,some home owners insurance cover this damages and they just replace the equipment since is not worth repairing.You can call Sony just to see how much they want for a new board.Let Us know if you need any more information.

Probable damage to the main board caused by lightening/storm activity.
It is possibly not ever going to be a successful repair.
Being LCD it is older technology and spares will be few and far between, not to mention expensive.
Thunder is just the noise. The damaging thing is lightning if it hits a power pole or your house. It causes a power spike of thousands of volts which damages every component inside your television. You claim against your power utility company with the complaint that they failed to regulate the voltage. You buy a replacement set. They may have small print that says it was 'An Act of God', in which case you claim against your home insurance. They often have a get out clause that you have to pay the first $1,000 of any claim. You need a new set.
High voltage from lightning damaged your TV. Many parts could have been damaged permanently. If the TV costs a few hundred dollars, It would probably be cheaper to buy a new TV than to get the one you got now repaired by a shop.
I think rain doesn't have anything to do, unless you had your printer outside...
Maybe a light interruption could make your station start over without proper settings. Try checking your printer driver and see if it has the proper settings for ribbon and not printing on black dots.
Yes!!! When going out for extended periods of time unplug TV's from a/c outlet AND dissconnect broadcast signal from TV(cable,sat. etc)
Isolation is the only sure protection against LIGHTNING DAMAGE!!!
I advise purchasing protection from your' service provider.
hello. you are not alone, this is a common problem with alot of new lcd and plasma tv's since they operate with high internal voltages the circuts have built in protection. any slight power fualt or short in the circut will cuase a sos or shutdown. may be a number of different reasons or even a shorted fuse.
it needs to be checked you have a power issue.
some models if there is a blinking led the number of blinks indicates the fualty area.
your tv needs service.
sounds like the convergence ICs and resistors due to the double image. You need two convergence ICs both STK392-110 ICs and the following six resistors. (2) 3.3 ohms 1watt resistors, (2) 1.8 ohm 1watt resistors. (1) 1.8 ohm 1watt resistors. (1) 3.9 ohm1watt resistor. You can get replacemnet ICs and resistors at the following link and they provide free instalation instructions so you can do the repair yourself. Heres the link. http://servicemanuals.vstore.ca/
