Tv picture been going washed out for a while now but switch it on and off and it seems to cure itself until this eve when it went the same again then turned itself off. When I turn it on the standby light goes from red to blue like normal but nothing else no picture or sound then after a minute or so goes back to standby on its own the model is LG50PS3000
How long have you had the set for?
When the set switches itself back to standby, does the power light start to blink?
2 years 9 months Yes the blue power light blinks twice then goes to solid red which is standby
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
Yes problem is the same
The most common cause of this problem in these sets, is failing capacitors in the power supply. They are similar to batteries, in that once they are charged, they can continue to run inedifinitely, but once they receive several surges, the resistance gets so low, that they act as a short, and can intermittently shut down. The solution is to have the capacitors replaced. Average cost for this type of repair is around $150 parts and labor.
