Dear all forumers,
I have a weird problem with the above says TV power supply.
Its first cant on and i had able to change the SMPS controller DLA001D i replace it with L6598D and its work fine.
But after the TV get warm Up, the relay will clicl and the power off it self.No green light at all. And its turn back on itself in a minit then off again.
Can someone plsase advise me what should i do next or should i just change the PSU?
thanks

Re: Sharp LC42a63m

It's almost sorda impossible to determine on exactly where the problem is located by the information given. First why was the SMPS needed to be replaced, was it totally Bad. Pictures of the back of TV helps us to determine closely on what to look for. I personally do not like to use other models of SMPS to fix a television. However in your case your one step ahead of the game by finding an alternative SMPS. Now again Pictures and Voltages can give us enough to help. BTW welcome to the forum.

Check all your soldering for cold or intermittent solder joints. Reseat all connectors.
