clean connections for T-Con board

If the only thing not reacting is the audio, then the audio board or the main board has gone bad. Enter the model number and tv make on you tube to get more detailed info.

My personal suggestion would be to go for these repair catalogs. I know this website reliable-store that i used to buy them from, and they sold online it was very good manual. Go ahead, I bet.

What does it do if you unhook the flat cables going from the tcon to the panel, does the blinking go away and do you have sound then?

One of my EDTVs has the same issue, though on a much smaller scale (it doesn't degrade the picture at all; it's only noticeable when the top of the screen is black, and it doesn't go down very far). Online reviews of the TV showed me it does have this problem commonly, so yours may too. It must be something you need to get it serviced for.

Hi there! One of reasons your tv not working, the thunder storm /lighting possibility has burnt your Tv micro processor. get a technician to check the power supply section too because during the thunder storm your TV circuitry received excessive voltage . If is the main processor is burnt you have to change it for the TV to work .

What is the model and make, there isn't a cooling system in a TV unless its plasma and nothing in there should be getting hot enough to where you hear sounds like a heater cooling down, I wouldn't use the set before having it checked out by a technician

Most likely a contact problem or broken track on one of the flexi circuits coming off the LCD screen - Repair shop would recommend a new screen. Some people have bodged repairs by putting pressure (layers if tape) on offending flexi circuit - see AVS forums - but this is definitely not recommended and if you are not skilled then working in the back of a TV can be lethal. My advice always buy LCD TVs with a 5 year warranty (Richer Sounds, JLP or similar).

This model of SONY TV uses a Samsung display panel, the problem you have is the panel went bad. SONY was offering an extended warranty to change the panel free, please call SONY to check it out that if they still offer the free replacement.

you have a leaking cap on your power supply /open up and check on just replace those caps that looks swollen

Check your owners manual for troubleshooting guide first. It could be something as simple as bad batteries in the remote.

You may have a defective main board.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. 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.
