Got a Panasonic CD stereo system SA-AK410 When I turn it off after a few seconds it turns back on. Is this normal?


That's because you haven't set the clock on the system. I jumps to DEMO mode once you turn it off without the clock set. Clock can be set through your remote. Hope this helps. Cheers.

NO POWER AT ALL


Hi
our tv set need to be serviced. Here are some tips:
1. Open main fuse. The fuse is clean but interrupted. You can try replacing it with one o the same value.
2. Fuse Blown or blackened. Short in the rectifier bridge or in the switching transistor. Out of the power supply: supply line rectifier (100/150V) shorted.

SHARP 21V-FK220M ALWAYS TURN OFF AFTER 2-3MINS.?


1) test the power supply: line cord, fuse, c.breaker, rectifier, switch, filter.
2) horizontal output +125vdc( HV transformer or flyback, +HV rectifier)
3) all other circuite +12vdc
4) vertical output +80vdc
see the b.diagram attached.
God bless you

TV does not come on at all.......would there be some replaceable fuse?


Hello
Certainly there will be a replacable glass cartridge type fuse. It will be there, not only for Sanyo, but for all TVs. The fuse used is for protection. That is, if anything wrong happens to the power supply or its internal circuits, fuse will blow up, and prevent further damage to other components. Therefore, you must understand that if fuse in your TV has blown up, certainley there will be some reson for that. Without find that reason, and rectify it, never put a fuse there, it it has blown. It will cause more trouble to your device. Check it well. Find out the reason for the blown out fuse. Rectify it first, and then put a new fuse there. OK.

Unit blew the internal fuse. SONY SA-WMS367 SUB-WOOFER


Bad output IC or voltage rectifier are the most likely at fault.

If it is a vertical line, change the horizontal output transistor + capacitors. If it is a horizontal line, replace vertical output transistor + capacitors. Both cost around $10-20.

POSSIBLE FAULT CODE


Yes, it is possible. The F61 error is a failure in the power supply or the amplifier. I repair these every day and it will require good soldering and troubleshooting skills to fix this yourself.

If you would like to try, let me know, and I will give you more information. But the best thing to do is take it to a service center and let a professional technician check it out for you.

Panasonic VCR PV-4652


If the MFD (Multi Function Flourescent Display is not working, check the -27 - 30 Volt (minus 27V to minus 30V) supply line. The fuse or a fuse resistor (around .5ohms 1/8W ) will be blown.

Also, it is possible that the 3V AC heater supply line is disconnected at some point.
Check that also.
