Something is not right, cooling, voltage, Mother board, peripheral. There is an overload or overtemp. Make sure fans and heatsink was properly installed, and PW Supply is putting out correct voltage.

Please stop telling people Rolex watches don't tick.


Yes, absolutely correct , all automatic watches tick and the fake Rolexes just tick a bit slower so it is more visible.

Bang oulfsen penter amp no power


you didn't leave much for details.. No Model number so I don't know if it's a car amp or a house amp... but I've found these very useful for solutions and support...

Service Manuals: http://beophile.com/?page_id=8253
Contact Company for support: http://beophile.com/?page_id=2202


Explain to them with full details and make / model & model number / serial number /

Only other idea is to probably buy a new one if these don't resolve your problem..

I don't have a manual for my small Black & Decker Smart Charger. I'm trying to charge the battery on my '07 Honda Rebel 250cc. It has settings for 2/6/12 volt batteries. How do I hook it...


Hi,

You just need to set black & decker charger to 12V . Don't make mistake while connecting + / - leads. + lead usually come with Red color cable. You can use the AVO tester to justify the lead cable. The charging time is normally about 10 -12 hours (or just just check the status on your charger display). If your charger does not has trickle charge facility, you have to disconnect your charger after 12 hours continuous use.

Also, you can find the guidance about your charger here :

My QSC PLX 2502 amp completely blew. Channel 1 has been giving me problems for a year and I have had the amp about 3 years. This past week it drove into the red so much and I could not stop it. Well now...


You should NOT drive the amplifier into the clipping mode continuously. There is a possibility that you have fried your speakers or that they are the real problem. You haven't told us what you were driving, however this amp will deliver 450 Watts per side RMS at 8 ohms which means your speakers have to be rated at least that much RMS power for continuous. When speaker voice coils fry, they can wipe out amplifiers. Let us know what speakers you are using and how they are configured. This amp is going to be expensive to repair I can tell by looking at the schematic: Here is the schematic:

http://elektrotanya.com/qsc_plx2502.pdf/download.html

Scroll down to "get manual" and click to download it. IGNORE other download links.

This amp has circuits to boost the power supplies to the amps to handle the peaks. It is rather complex but the schematics are complete and have good explanations... some of the best I have seen. There are going to be a lot of destroyed components and great care has to be used after repair to "cold start" the unit to make sure nothing else is bad or it will blow up again. Most people do NOT have trouble with the QSC amps... so do tell me what speakers you are using and how they are configured so we can verify the design is correct. This amp is rated for 8 ohms so USUALLY only ONE speaker can be connected per side... and finding an 8 ohm speaker that can take 450 watts continuous RMS isn't easy. People fall for the advertising claiming "Peak" and "Program" power which are FAKE advertising... ONLY use continuous RMS power when sizing amps and speakers. There are MANY ways to cook out equipment... One is to boost the bass or the treble way up. Another is to NOT use balanced interconnect lines between mixers and your amps. Yet another is to NOT power ALL interconnected equipment from a single receptacle or power conditioning module. Please describe your setup further so I can help you more!

My amp will turn on and even when I have the guitar and amp connected no sound comes from the amp. I don't know what to try to fix it, so I have left it alone, testing it every once in a while (it...


Possibly a loose connection, or bad solder connection. unplug it from power.

If you think you are up to it geta soldering iron and some solder, and a screwdriver, and take the amp part out. be careful of the speaker wires. put some tape on each one and label them so you know where to put them back. after you got it out you might have to take some more screws out to get the board off of the chasis, so you can see under it. this is where all the components are soldered to the board. maybe use a magnifying glass. touch up anything that looks questionable.
do all over. you don't need to know what everything does if you just go all over. careful not to cause any shorts. you might see something that obviously needs to be fixed. you have found a problem. you can't fix something if you don't find a problem. do all over anyway if you think you still have to.

Put it back well enough to test it. then put it all the way back together, or continue to look for a problem, or take it to someone, like me!


Good luck

Likely the amp blew and the power supply is being overloaded and keeps trying to power on but finds an overload and continues as the power goes away. This is NOT a DIY unless your are electronically adept.

I have a caver preamp high fidelity control console model c- 4000 and I have a power amp.I don't know how to set it up to work thank you.


Can't find the manual.

Outs to Ins. Only connect a turntable to a PHONO connnector.

MAIN OUT to the unidentified amp's IN.

Don't slave too much power-hungry gear off the convenience outlets of the preamp.

Does a 1997 grand gt 3.1 liter have rack & pinion steering? I'm told the power steering went out and I don't know if it might be the pump or what.


Your car does have rack and pinion steering. If all of the fluid leaked out somewhere and you continued to drive, you probably have 2 problems to repair:

1. What ever started leaking (return hose, rack, pressure hose, or could just be the pump itself)
2. Power steering pump was damaged from lack of lubrication (fluid)
