Hi,

Have you tried keeping the unit unplugged for sometime?

Have you tried a different input?

Have you tried a different power outlet?

What is the colour of the standby light after it turns on?

Could you please let me know what is the model no.?

Do you hear any cracking or popping sound?

Regards

olevia540-b11. I have tried all that you have asked. There is no colour of the standby light. Nothing comes on at all. However, when i plug the tv cord into the wall outlet it sounds like it's going to come on but, nothing happens.
Expert:  PramitP replied 5 years ago.
Hi,

From your description the problem seems to have occurred with the power supply. Most likely it seems that the power supply has failed. There might be a faulty capacitor or bad fuses resulting in burnt off resistors and transistors. There might be bad ICs and diodes. So the PSU also needs to be checked. I rather suspect bad ICs and Diodes in the PSU. But you will have to check for bad caps and other components too.
If you want to repair it yourself then you should be having proper knowledge about the internal circuitry of the TV.
You should also require a multimeter and soldering equipments and schematics.
If you wish to take it to a repair shop would you like to have an idea of the cost of repair?
If you have any other queries then I owuld be glad to assist you further.

there was a power outage in the area where i live in. all the electricity stopped working in the entire house. when the power was restored all electrical appliances were restored, except the olevia tv. the other tvs and cable box radios work fine, with no problems.

It seems like the fuse must have blown out.
If you have any other queries then I would be glad to assist you further.
