Where do I find the fuse for my Panasonic TC-P50X5 tv

This is a very common issue with this model TV, you have bad capacitors on the power supply board, try this first, take a blow dryer and set it by the heat fins on the back of the set, turn it on for about 10 mins, plug the TV back in and there is a good chance it will work again and keep working as long as it's not unplugged. The correct way to fix it is replacing the 3 defective caps in a row towards the bottom of the board, I don't have the numbers but if you want to replace them I can get you the numbers but that involves soldering skills and purchasing new capacitors (new ones can be purchased at digikey.com) last option is replace the power supply board if you can find one. Do NOT buy a board from ebay unless you want another defective board. Hope this helps

MAIN PSU

The red light on front should be blinking count the number of times and check out what the code signifies and then you check out the board suggested.

The PANASONIC TC-P50X5 Y SUSTAIN BOARD TNPA5593 would be blown. See the link below.

Being in the field of electronics I can not stress this enough....POWER SURGE PROTECTION...and I am not talking about a power strip with "surge protection"...they are useless. That being said you had a surge that most likely blew out your main power board. There is a fuse on that board and if you are lucky that popped and it is an easy fix. If not, you will have to remove the board, get the numbers on it and search out a replacement. There are plenty of places online to get them but I use Allied Electronics. One thing to check while you have the tv apart is to check all boards for visible burn marks or damage from the surge.

When you are convinced the mains cable is good, and in a socket with power, then you should try to switch it of an on with the power on switch on the TV. Not with the remote control. If that does not change anything I'm afraid there is something wrong. Cold be a fuse, but all other parts, like in the power supply or in all other circuit boards, could have a failure. It takes skill, measurement tools and time to diagnose what exact. It can't be done over the internet.

power supply module is known to go bad on flat TV's, if you change it make sure you buy the upgraded model, because same model could go bad soon again. but I would check power to wall outlet as first option. and power cord as second.

hi is it totally dead if so it's possible the fuse inside could have blown, this will be on the power board, glass type, if it has and you replace it and blows again then there's a dead short on the power board or on main board hope it helps
