Where are the fuses located on the Pansonic CT-32SX31 32" TV?
CT-32HX41, bought in 2002. Had it on and suddenly it turned off. Can't turn it on, no click when pushing on button, no sounds, no red light.

Re: Won't turn on
Once you take the back off there is a glass gma fuse withing a few inches of where the power cord plugs into the board at. This should be a 6.3 or 6.5 gma fuse. Very common to blow in your model because the degausing coil is a little to big for it. There are other reasons for it to blow but 99% of the time you change change it and the set will work again. Let me know if you need more help or info!

if their is no any power indicator at the front panel the cause is either the primary fuse at the power supply section blown. and then if the fuse is blown that was mean the regulator transistor and the horizontal out put transistor could also damaged. this case can be hand held by trained technician. if you want a do it with your own just make sure you have at least a basic knowledge in electronic repair since you are dealing with some high voltage parts a care must be needed.
This is a bad connection in the power supply, or a bad connection in the high voltage supply, and could also be expensive to repair if the regulator board is intermittent. I say if you can take it back, good riddance. Good Luck
The fuse is located on the power supply board. It looks like a small glass tube with metal caps at both ends like the ones in the image below on the board next to it you will see a small marking that says the specifications of the fuse. Ex: 10A(Read 10 Amperes), 120V. The replacement you are gonna purchase should be of the same specifications. Make sure you unplug the tv from the power supply before replacing it so that you will avoid the risk of electric shock. A positive rating for the advice provided will be highly appreciated and I will be glad to assist you further if you need more help.
I have one of those that is the same age and the 6.3 amp fuse was blown out. I replaced it with a 6 amp fuse (i could not find 6.3 nearby) and got a few more weeks use until the fuse blew out again. someone suggested i get a slow blow fuse next time.
This denotes a problem with the switching power supply or the high voltage power supply. what is happening is the safety relay is being actuated by the shutdown circuit. Any number of things can cause this proble but more then likely the problem is in the high voltage power supply section and or its associative circuitry. The switching power supply and the high voltages power supply have very dangerous voltages and I would not suggest that you work on the TV set unless you do have a background in electronics. If you do not I would suggest that you take the TV set to an electronics shop for repairs. If you do have a background in electronics, you will need the following items:
1) A schematic diagram (to know where voltage and signal test points are located and to have a reference of the levels.
2) A multimeter (to measure the DC voltage levels on the TV Set)
3) An oscilloscope (to measuer the AC voltage and signal levels in the TV set and compair them to the values in the schematic)
4) A signal generator (to generate a reference signal for troubleshooting)
These sets have a number of problems like yours which are associated with bad solder connections or cold solder joints. On this set one pin on the the start-up relay is usually open or intermittent
The solution is to resolder connections on main p.c board. and especially on the vertical output
IC. Also change the caps in the vertical section to avoid future problems. Scrivitron.
