Our Sharp LCD model LC-20SH21U tv picture freezes. This use to happen occasionally. We would unplug it, wait a couple of minutes, re-plug and the TV would work fine. Today, it will not unfreeze. Tried the uplug -plug procedure about 5 times with no success.

Any thoughts would be appreciated.

If your lucky , the problem will be some bad caps in the power supply.If thats not it then it's trash time as the repair parts cost more than a replacement tv.
Just in case your not able to replace component parts the power supply part # is ... 9NK4900210880 cost abot $60.00.The main board part # is.. 9NK5600600286 cost about $260.00 and may not be available.
