    Sharp lc40f22e 17pw26-4

    hi guys.. picked up this set.. Had flashing standby light.. went ahead and replaced all capacitors and a single uf5402 diode.. set powered up and appeared to be working just fine for a good hour... went to turn it back on later after turning it off and nothing.. no lights completely dead... but now I've turned it on again and now it appears to be working again... it's making quite a loudish hissing noise now though... Any ideas what might be wrong? ideally looking got a quick fix or common problem as this is taking up far too much space in my house and the Mrs ain't happy lol

    Cheers guys

    Have you taken any voltage readings when on and then when it turns itself off. Any photo's of the circuit boards?
    Willing to help but I'm no expert.
