Hi there!
If the fuse rating is correct as indicated on the board, then the PTC is probably busy going faulty. If not sure where it is located, normally on the front where the switch is and where the coil that sits around the tube is connected to the board. Little plastic box with three pins(sometimes two) black or cream in colour. Some circuits use a disc type with 2 legs, however not sure on your set. This is called the degausing circuit and demagnetises the tube every time you switch the TV on. Good luck, JUS004

Tv does not come on-no lights at all


This set has a pair of common issues----one: the fuse (6.3 amp and special--do not replace with Radio Shack or generic fuse) blows for no reason---with back off follow power cord (unplugged please) direct to the fuse which snaps into a holder--if stand of wire inside is broken or black replace the fuse with (not generic cheap fuse) correct fuse.

A few of these sets had problems with the degaussing circuit but that is rare----9 out of 10 times replacing the blown or open fuse with the CORRECT one returns set to operation.

I stress that as saw one where a guy replaced the fuse 3 times in a row in a few days with a generic one that popped at turn on.

Fuse keeps blowing out on Panasonic CT36HL44J TV


Thanks for this post. It inspired me to replace my fuse in my TV and it is working great now... I took pics of the process in case anybody wants to see what they are in for. http://joedotcom.com/2009/09/01/panasonic-fuse/ Although I did use a 6.3a fuse (just like I removed). I read on another forum that you can replace it with a 7a fuse and get better results. I have had this TV for years and this is the first blown fuse. If it becomes a reoccuring theme, i may up it to the 7a.

Main fuse blown on CT-32G11 32" Panasonic TV, Replacement fuses continue to blow.


If the main fuse keeps blowing, check the horizontal output transistor for a shorted condition and diodes in that section as well.

RCA 32V430T 32" won't turn on!


The fuse is inside the set and is probably ok, but check to be sure. If you have an ohm meter I would check the horizontal output transistor first. It is a big transistor on a heat sink next to the FBT. It has three pins, check the center pin to one of the others, if low the transistor and probably the FBT is bad.

Fuse keeps blowing


NEVER EVER replace a fuse and think that va fuse will blow all by itself. The fuses are there to protect the set from catching on fire incase theres a short inside the set. Now in some cases an intermittant short can work after you replace the fuse but if its burnt black or brownish, theres a short inside the set in one of the circuits. always use a 100 watt light bulb across a blown fuse if your not sure if there is a short. if there is, the light will absorb the short and glow bright. if there is no short the bulb will glow bright , then go down very dim. you could have a main power supply problem, such as shorted bridge rectifyers,shorted main b+ capacitor, Hot could be shorted, or the Vertical or audio output IC could be shorted

Toshiba 27A30 that blows Fuse


Jeff, If your not a technician please dont mess with the set as you can get seriuoly hurt by experimenting. And replacing a fuse that is black is only going to blow again and possibly cause more problems and damage the set more then it already is. Your problem is a shorted B+ rectifier or a capacitor or voltage regulator IC. If you don,t know what this is, or you don't know how to solder, as well as unsolder, Please seek out a pro to assit you with this repair. Good Luck

On Timer light flashing on my TV


If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. good luck!
