Hi All,
Sorry to say, this set came back into the workshop today Mon.25th Jan.
And is stuck in st,by. The weird thing is sometimes it will power up as normal, but only from the remote control,it never starts from standby button. And all is o.k. until switched off/and then just sits back in st,by. Have replaced/ checked all elect.caps in p.supply.Also tried heating with hairdryer all to no effect.
The p.supply volts. all seem o.k. i.e. 24v,12v,5v, and3.3v
and stay the same when set is running!
As you can see from previous posts Tony kindly reprogammed the eprom for me, and set has run well until now
Help!!
Bri. :wallbash:

Sorry to bump up an old post but I've got a Technsonic LCD3251 which is stuck on standby. I'm pretty tech savvy except with TV sets. Can someone help me with a repair? I would be very grateful.

Thanks!

I have a load of working PSUs that I was replacing under warranty so if you post a pic of the panel I'll see if they are the same.
