Facing TV Problems? Ask a TV Technician.
Hi and welcome to Just Answer. I'm sorry to hear about your TV. To help me, can you tell me the make and model of the TV?
How old do you think it is?
No lamps at all? You may want to check the fuse in the power supply.
Is this something you can do? The power supply is going to be on the other end of the power cord, inside the TV.
If the fuse is good but the set is dead, then you have a bad component in that power supply section. Possibly the bridge diodes, regulator - it could be one of several things.
I think you will have to have it checked out by a pro with a meter and a scope. Something has popped but it is going to be tough to track it down without being there in the room.
Most TV techs will charge about $70 to diagnose a TV and give you an estimate. I don't think the repair charge will be much more.
I'm sorry I can't help you further. The problem is in your power supply.
