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

Lg 50pq20d plasma tv not switching on but voice comes out


Aside from checking the fuses it likely will require a technician or a shop to examine the set to see what is wrong and what needs to be replaced.

Sounds like a power supply issue but that would need to be checked.

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 going to LG 42 inch plasma, tried changing fuse in plug and tried a different power lead and still nothing (no standby light etc)


Hello,
since you have change the fuse in plug, this indicate that your plug is okay, the likely problem is from the television which will require you to open the television to check for fuses, bulged capacitors, but if otherwise your power supply is dead.It can be dead at anytimes.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
Hope this help.....

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

Dell w4201c burning fuse...


hello, definitely if your fuses are blown and your not able to circut trace and find the fualty compnents on the pb then repalce it with a working power supply this may help but also keep in mind you may want to check everything out first get your models service manual so you can verify voltages at test points. something is cuasing the fuses to blow so if you do change the power board and you blow the fuses again then you will need to trace the circut and find out where the short is and what panel or part is cuasing it .

hope this helps
