Question about Computers & Internet
Can you please advise what is the panamax 1000 the only panamax I now is for headaches!

I had the same problem with the overvoltage light coming on in error right after powering up my Panamax 1000+. In fact I have two Panamax 1000+ that developed this problem so it seems to be a common problem with the Panamax 1000+. However I was playing around with one of them turning power on and off and it started working and I've been leaving it on all of the time and it's been working fine now for quite awhile now. This got me to thinking that the problem was probably a bad electrolytic capacitor which can deteriorate due to the aging or long periods of non use. Electrolytic capacitors are usually the first components to fail in older electronic equipent. I looked inside and found there were only four electrolytic capacitors so I decided to change all four in the one that wasn't working and showing a continous overvoltage light right after power up. After changing all four electrolytic caps, I powered it up and it is now working normal again with no overvoltage light anymore when powering up. I bought the four electrolytic caps for about about $7 at Fry's Electronics. You will need two 4.7uf 50V, one 220uf 35V, and one 22uf 25V. Make sure the caps you buy have both leads on the same side and one lead is marked negative. If you have soldering skills you can change these yourself being careful to make sure the polarity is correct as the negative side will be marked "--" or have a black bar on the negative side. Otherwise you could take it to a repair shop and have them change the caps for you.

Im having the same problem with mine...trying to figure this out..

The problem is due to a poorly engineered power supply. The power supply puts excessive ripple on filter cap C8 - a 220uf 35V cap - and runs it warm enough so it has a limited life. Replacing C8 will fix the problem for a few years. There's also a dropping resistor, 100 ohm, that runs quite warm with 9 volts of AV across it. But it seems to stand up to the abuse, even though it looks like a 1/2 watt resistor.
