LCD Standby issues..

[gaza007]

Hi All..

I'm trying to find an answer to a problem that's driving me mad!

I have a 32" Onyx LCD TV. Model number SW3210LCD

The Tv is stuck with just the red standby light on and no matter what you press on the remote or the Tv itself it will not switch on.

I have replaced the power board with a similar spec board thinking that this could be the problem, but, after replacing it today nothing has changed! The same light comes on but nothing after.

I have also checked all the boards for blown capacitors and fuses.

I thought maybe it could be the switch but it has an inbuilt on off switch 'presumeably to save you reaching for the plug on a night time and the normal power switch. But surely the remote would factor that switch out?? I'm just wondering if there is anything I have to do to the new board likes of a reset to get it working again?:

Any help would be most appreciated! Thanks for looking everyone!

The usual process is to perform a few simple tests to make sure the fault is the power supply BEFORE ordering a replacement.

Virtually every LCD television uses a dual power supply. The standby supply is on whenever the TV is plugged in. The main supply is switched on and off by the main board. It's a good idea to determine if the main board is trying to turn on the main supply and failing (power supply problem) or is not trying to turn on the main supply (main board problem).

Re: LCD Standby issues..

Thank you for your reply.. Sorry I didn't reply sooner but, I only just realised that I don't have email alerts turned on to notify me of responses.

I bought the part on reccomendation from the person I bought the tv off. They had the same problem a couple of year back and the tv repair man told them it was the power board.. I'll try and upload a picture of the internals to highlight the board I mean.
Anyway after replacing said board, nothing has happened. So obviously it wasn't this board or as I mentioned before, Is there something I have to do when replacing a board?
Thanks again , and I'll try and upload now.

In general, no.
