Power supply green light comes on but unit does not power up.


When you say 'checked leads' does this mean you checked to see if they were firmly plugged in? or that there was power on the power leads... If there is power, you probably have a 'smoked' drive. If no power on the leads more than likely a blown fuse in your power supply.

Not getting any power through to tv. plug/fuse ok. what next?


There should be a round black rod about 1/8" in diamater, that is the circuit breaker, press it to reset and if it comes on and stays you have solved the problem, if not best get a service tech.

Hitachi LCD TV Dead


There is a internal fuse on the power supply board. When you plug in the set, does the standby light come on?

Wharfedale LCD2710HDAF no power to tv, checked cable and changed fuse a few times, new power lead? or is this a common problem?


Hi.

The power cord must be checked using a multimeter. The test is done reading impedance (ohms) between plug's prongs and contacts to TV power board.

If the power cord is OK and there is no power, then the problem is the power board inside the TV.

Regards.

Ginko.

Sony wega KE-42M1 .power lead ok . no power at tv. (no standby or power light showing at on switch). house power went off , when it came on tv wouldn't work


This confirms that the main power supply which is the SMPS is faulty.
The fuse could have failed and must be checked, if the fuse fails the SMPS is confirmed to be faulty due to the power outage.

No power - have checked fuses, power leads and master switch


Well yes, there a problem in the power supply modual.
It does sound like a failing power supply , becuse of the
fact you don't get charge up spark from the plug , wich is normal
affter it's been off /unpluged for 20 min or so .

check the resistance of the plug coming from the set with a volt meter if you have 10 meg ohms or higher,
it's an open circuit and more than likely a 1.50 fuse in the power
supply. If the fuse blows instantly then it's a shorted output transistor or rectifier diode in the switching power supply.


Be a shame to pay 300.00 plus for a stupid fuse.

hope that helps a little . if you have any questions just comment
an i'll respond
.
