Toshiba 57h83 wont do nothing

Yes, it can be fixed but you have multiple problems. By the time you replace all that has to be you would be better off buying another disposable TV.

there is some shorting in the main board

Bad caps in the power supply must be replaced .

Replaced the sc board and tv works fine again.

I need to know how long do you have the tv?In the other word,approx. how many hours you have put into it?
Secondly,did you wall mounted the tv or setting it close the the area which there is not much room for the back of your tv to breath?

the relay is kickking in but a failure in one of the boards is preventing the tv from powering up (protection circut ) and only qualified service centers have access to these parts

Clicking sound is power relay engaging. If all systems are not functioning properly, unit will shut down to prevent further damage and/or fire hazard

Is the front panel power led flashing by chance?

Hello ****, I have the same problem. However. I manage to get the TV on by pulling the cable out and then plug it back in again several times. A couple of times just after you have heard the first click and the a couple of times just when you hear the second click. Sudenly the TV decided to work again. I think it must be a problem with one of the two relays that sits next to each other near the centre of the TV. If you take the back of and then plug the power back in you will see the two lights next to those relays come on and then die out when the relays let go. This is what hapens if the TV doesnt work. If the TV works those lights/LED's will stay green and the relays will hold on and feeding the TV screen. I will probably try to see if I can buy replacement relays and replace these. If I can get hold of them, then probably I would take the existing relays appart to see if I could see any fault. If those relays ar ok and the replacement relays appear in the same manor like the old ones I would look for problems before those relays. Maby order a new circut board from Samsung.
