TV lost it's picture...Only have sound

Yup.... these new sets are throw aways, they intented to fill our land fills. Extented warranty is the way to go. I have determined that plasma is the way to go because the display is less prone to failure. LCD panels are prone to scratches, heat, cold, excessive pressure and back light failures. Although plasma are made of glass and can crack I feel they are more durable.

About your set. if you are a tech try this.... use caution.

Unplug set.

Remove back.

With set on stand and circuit board exposed.

Get a can of can air, turn it upside down this will spray a liquid instead of air.

Spray a circuit board until it's very cold.

Plug the set to a outlet and turn it on and see if there is picture change.

Do this to other boards, REMEMBER to UNPLUG set from outlet before spraying boards.

DO NOT allow spray to touch skin the spray gets down to -100 degrees and will cause frost bite.

You can also try the above using a hair dryer to get the boards to about 110 to 120 degrees.

This may isolate the problem to a board or to a component.

Remember use ths at your own risk.
