Monster cable hts-5000 power center received a voltage surge, and evidently, the fuse, or protection circuit sacraficed itself, and monster no longer services this discontinued model. is there a way to purchase a relacement fuselink,etc to make the repair myself, or a service center that can effect the repair?

Most UPS's have split power. One is for Surge protected which is probably the half still working. The other come from a switching device called a relay. The relay is on the circuit board inside. If the battery backup'd half is dead, then that relaying is not connecting the power source to the three outlets. It could be due to a defective control circuit or the relay is bad. If you dont know electronics, either buy a whole new unit, or send it in for a rebuild with a place that knows what they doing. The manufacturers approved service places charge a reasonable price, but wont tell you anything for DIYers. I found a place in western canada that services them and does correspond with tips...that worked. And the obvious warning, the insides of a UPS can kill you if you dont take proper precautions
UPS – UNINTERRUPTIBLE POWER SUPPLY Uninterruptible power supplies provide protection against mains power faults to computer equipment. These faults include voltage spikes/interference, over voltage and under voltage, mains supply interruptions and surge protection etc. These faults can cause computer and electronic equipment that are connected to an unprotected mains supply to malfunction and/or sometimes fail. A common problem, when burning Cds, DVDs etc. any slight power interruptions to the burning process will halt the recording process and rendered the disc useless. There two type of Uninterruptible Power Supplies The lower powered and cheaper type UPS are switch-over types, when the mains supply fails, the UPS switches over to the batteries and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails. NOTE : The mains waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave). The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and then the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.
Maybe you have many overvoltage situations at your area, that the UPS can't handle. It's a good idea to put before the ups an overvoltage protection or a stabilizer. Ask the manufacture for the overvoltage protection of the ups that can handle.
I had the same model/symptoms (no lights on the front panel). I had a compatible, though smaller, battery from a Verizon Fios backup unit, and I tried that in the UPS--it worked. That confirmed that I just needed a new battery.
I have to answer this question with just plain old common sense. Get a new one! This is crazy. If you get a new one, you will have a better, more upto date and something you can handle with todays OS and obviously new batteries. That is too old to mess with. I fixed a powerware once and the plastic was falling apart and the PC board was held together with a rubber band. Not worth it.
Had similar problem. Paraphrasing the warranty info sheet (with concurrance of my Geek Squad friends), our HT800s have sacrificed themselves to protect our components. They tell me it is possible for only one circuit in a home to have an electrical surge. That is why the TV in one room may "blow" and the adjoining room TV not. Bottom line: Time to buy a new surge protector.
First, most of the UPS sensitivity can be adjusted. Setting a higher sensitivity will make the UPS compensable much faster if the current goes to high to too low thus always providing a good power quality to the equipments. For example, on a BackUPS RS the low level can be configured from 94V to 104V and the high level from 126V to 136V. An entry-level UPS such as the APC BackUPS ES will switch to battery mode as soon as the power goes out of the sensitivity range. On the other hand, a high-end UPS for workstation like the APC BackUPS RS has a feature called Automatic Voltage Regulation (AVR) that compensate at some extent without requiring the battery; this makes the battery last longer before needing to be replaced.
Second, most of the UPS have "Battery Protected" and "Surge only" outlets. Make sure that the computers are connected to the "Battery Protected". The "Surge only" outlets will only protect from parasites or surges like a thunder storm. They should be used for less important stuff like a desk lamp or devices with high demand peek such as a laser printer.
Third, the use of a power bar connected to the "Battery Protected" side should not have any impact as long as it is not overloading the UPS. Personnaly, I have a power bar connected to both my UPS.
