Im having the same problem with mine. The problem seems to have started after I placed a vcr on top of the unit. I am thinking that It may be getting too hot. But don't really know.

Thanks for using FixYa.

I have had many Techniques receivers and I think they are great to own. I would try adding two more speakers. I have the Techniques tower Speakers 12" 10" 51/2 3" Got to Lov em'

hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

The question is what is causing the overload? The power supply or the output devices on the heat sink?
If you have accidently shorted a speaker wire, then the answer will be output devices, otherwise it could be anything in the power section. You may find a burnt or damged device with either of the causes.

TV is not customarily a sound source. It is a video destination. Get your TV-related audio to the receiver from the same places the TV gets it - each source device's audio outputs.

First of all the KEF is a powered sub which means that it wants a line level signal NOT a speaker level. Send the signal from a tape output or pre-amp output to the sub input. The overload is because the impedence load for the speaker output is too low and looks like a short to the amp. Continued attempts to connect the system as described will result in damage to the output section of the amp.

Please let me know if you need more info.

Disconnect all speakers at the receiver then turn it back on. If it still goes into "overload" you need to have the unit serviced. If it stays on, post a comment and I can walk you thru troubleshooting your system.

You just connect it in the auxilliary input then switch your reciever to auxilliary so you can the sound of your ipod. First buy a wire connector from ipod to reciever.

Hope it may helps;

They have the manual posted on the Panasonic web site.

F70 means Blown Internal Fuse change the internal fuse and that should solve the problem if not you may have to change the output

If you feel confident doing so, you could attempt to open the cassette deck and physically examine the gears to check for damage or debris that might be obstructing them. But do remember that there are risks involved when opening electronic equipment, especially if you're not used with doing this kind of work. If you're not sure you can do this securely, it would be preferable to get assistance from a qualified audio equipment repair specialist.

Could be one channel has failed in the amplifier caused by 40 year old components failing. Could be a shorted speaker lead, damaging the amplifier. Job to say without seeing it on the work bench with test gear.

I would check the weight and allignment.

The cueing mechanism should lift and lower the tone arm regardless of whether there is oil in the cylinder or not. The silicon oil is used to dampen the movement. If the lever does not operate the tonearm, then there is mechanical damage under the platter.

Were you expecting an electronic powered unit to work without power ... No power = No output.

Question edited for spelling and add some SPACES! Did you look for bulging electrolytic capacitors? If you can't see any, then you need to take it to a service centre, as they have thousands of dollars of test equipment and access to parts. ..

Probably dirty contacts in the tone control section.
