How can I fix the pv1500 amplifier .it work well but as I switch it off and on again it fail I switch on with dim blinking leds


I would start by checking that the cooling fans are not obstructed, or dirty. It sounds like the amplifier is running right on the edge of thermal cut off (100 degrees for this amp) and when it switches off, rises just above this when the fan stops spinning, not allowing the amp to start again.

I am however just speculating, I've only had a quick look at the schematic.

I'd recommend having the amplifiers serviced by a qualified person, so they can adjust the idle current and check for any bigger problems. Good luck.

SHOWS LENSE ERROR, RESTART THE CAMERA, AND SHUTDOWN AUTOMATICALLY CANON A 1000 IS POWERSHOT MODEL


Unfortunately, many cameras that fall prey to lens error problems can only be corrected by professional repair. But, here are some last resort troubleshooting steps that you can try that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try.

I CAN NOT GET ALL 5 SPEAKERS TO WORK


I know this is not the answer that you want to hear, but: That television is not capable of delivering audio output to all 5 speakers - it is a stereo-only TV, which only delivers 2 channels.

Furthermore, that Coby DVD-937 only has Digital Audio outputs rather than inputs, which is very strange and complicates our problem immensely. You will get 5-channels with DVD or radio play, but getting 5 channels for TV is not possible without additional equipment.

The manual for the Coby mentions a "Digital Decoder Amplifier," which would work. You would connect a digital audio cable from the area marked "Coaxial" on the back of the Coby to a digital audio IN on the back of an external amplifier. You would connect the speakers to this amplifier, instead of directly to the back of the Coby. Then you would need a cable or satellite box with digital audio outs (fairly common nowadays) to another digital audio IN on the back of the amplifier. The cable or sat box you may have already, but you may need to purchase such a "Digital Decoder Amplifier" or other digital amplifier with appropriate speaker wires and 2 digital audio input slots (not to mention two digital audio cables). Fairly complex. Possibly expensive.

Subwoofer acting wierd


If you turn the power off and restart, the most logical answer i know of is your amplifier is going bad.
I am not sure of the model and brand of your amplifier, but there should be a protection light on the amplifier somewhere that will most likely be on, caused by overloading the amplifier.

You will most likely have to replace the amplifier, or check with the manufacturer to find out if they can repair it or help to further diagnose the problem.
