Open up your TV cover housing, and look for the fuse. If it is busted,
have it replaced. Put the cover/housing back in place and power up
your TV set. Send us an e-mail and let us know.

It may be a fuse. But something else may have blown the fuse. I would check the circuity of the power supply.

My TV worked fine this morning,Turned it off,Went back to put it on and now it won't turn on at all,Why?


Maybe faulty power switch or its blown a fuse or the powwer supply inside the TV is kaput.
If its out of warranty get in touch with a reputable TV mechanic and ask them to come and repair it. It might be good to get a ballpark figure on how much it's going to cost.
Good Luck

Tv was working fine yesterday. got up today and nothing.


Dear,

can u do repairing or have you ever troubleshoot the issue by yourself.
if yes, then open the cover and check the continuety of the power cable because it can be the damage cable. if all of then check the fuse inside the circuit board where the main power cord goes. the must be a glass fuse. Check is it in working condition means having continuty too.
if this component is ok then u have to check the other circuitry.

regards,

HITACHI 37PD5200 E Plasma dead.


The fuse is either open or it will have continuity do you have any standby voltages

The problem is in the standby power section. Check the fuse, R607, or burnt IC601, fuse R612 and VD relay 601 should show open. Its possible it could be the high voltage area of the power supply. You can try unplugging the set and cable and let it sit 4 to 6 hours. This is a hard reset. If it still doesn't turn on after the hard reset and the fuses and relays are fine, and you don't smell anything or see anything burnt. Then you'll need to call a TV repair man. They normal start around $150-$200 to fix the set. I hope this helps.
