How to fix this problem Sony lcd TV bravia 40 inch

SOURCE: Sony Bravia 40" LCD TV generating heat.

First, you will have to define what you mean by "hot to touch" ie.:
can you or can you not hold your hand on it for a few moments.

Hi,

It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty

The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.

All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.

The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"

Thanks

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

Could be the decoder:

1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)

What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.

Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.

1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.

So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.

I sure this will help.
