Fixing an LCD TV?

Question

my lcd tv would not come on at all yesterday morning

and after checking all the fuses and pushing all the wiring ports it came on perfect.

following morning turned it on and it did not work again so i did the same but it still would not come on.

after a little investigating and cosemplating sticking it in the bin i used a hair dryer to warm up the components by blowing it down the air vents at the back for 10 seconds and keeping the power button held in the on position it works perfect.

you can power on and off with standby and picture and sound is great.

the problem is that every morning i have to repeat the hairdryer trick and would like to know if anyone knows what could be wrong with it and will it cost a lot to fix it?

also how much would it be worth in its present condition?

the tv is a walfhedale 32inch lcd with biult in digital tv.

thanks for any feed back.

If you live a very humid place, then your TV just doesn't like your environment, and other than trying to make your place less humid, tough luck.

That said, these humidity related problem shouldn't occur unless your area's climate has over 85% relative humidity most of the time. 85% RH is what a lot electronics equipment, particularly computers, is rated for.

If not, then maybe it will have to be repaired, but it doesn't sound like a problem with the LCD panel itself, so the repair cost may still be tolerable.  However, if it is an old model, say 3 years+, you may want to consider getting a new one.
