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

Automatic transmission not shifting gears


Replacing any fuse after it has blown ,your almost
guaranteed it will blow again

At least you know the circuit with the problem

Now you go to factory wiring diagrams, to see what that
fuse controls & do some testing

Have to have wiring diagrams,be able to read them & know
basic electricity & be able to test your vehicle,then you have
to be able to continue on with professional tools, once the fuse
issue is resolved, if the fuse keeps blowing every few days

You could have wiring issues,more likely inside the trans in the oily
environment ,you could have solenoid or module failure or mechanical trans issues

I would say you can't resolve at home,need professional help

ECI Fuse keeps blowing


What ever was blowing the fuse intermittently now has a full blow dead short. Trace it through to the unit and check for connections shorting out or the unit itself shorting out.

Keep blowing the main fuse.


To which circuit section did you replaced the fuse? Main power retulator? Just understand, the fuses are used to protect the circuit and TV from any short circuit or over voltage. Without any one of these, no fuse will blow up. If it was due to over voltage, the set should work after a fuse replacement. But here, the fuse blow up again, means, there is some thing shorted component/s. Check which component is shorted, and replace it, before replacing an other fuse. One more thing to say is, never insert a fuse other than specified. The voltage and ampere specification to fuse, will be marked at the circuit board, very near to the fuse clamp. Insert a fuse of same rating only. Using other fuse, rated higher ampere rating, might make things worse.

Can't find 2A 125v fuse replacement for on-off will 250v be OK?


There is no difference between a 125v and 250v fuse. The most important thing is the 2Amp. This fuse is probably the line fuse and could be the only trouble and may have blow with a line surge. Make sure the 2A you use is a Fast Blow Type. If it does blow again you most likely have a internal power supply failure.

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.

P0440


The canister vent valve and the oxygen sensors get their power from this fuse(along with some other things) wich means you could have a bad component or a wiring problem anywhere between them and that blown fuse. You can try to unplug each component and try it again. just a suggestion - try the oxygen sensors first as they have a heater circuit inside them wich can short out. The pink and black wire going to the vent valve should be 12 volts with a good fuse in that circuit. Get a circuit breaker from radio shack or napa to go into that blowing fuse so you don't keep having to throw all your fuses out after you blow them. The po440 means you have a small leak in the evap system but you need to repair the blowing fuse first wich could also have something to do with the vent valve- they go bad very often.- good luck

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.
