Looks like switch mode power supply is tripping due to component breakdown--a specialist repair I'm afraid.

CCTV power supply keeps decreasing the voltage

Your power supply appears to have a capacitor that is breaking down located within the diode bridge. You will need to replace the power supply or get it repaired.

Laptop intermittently beeps and stop charging battery. Screen dims when this happens (not as bright). Unplugging the cord and plugging it back in fixes the problem sometimes. Replaced cord two times,...

Take the notebook to the tech, ask them to check for any lose connections on the power inlet socket inside the laptop, where it is connected with the motherboard. Perhaps, some small solder-joints, or tiny contacts have come off and are on/off depending on the notebook's/power supply jack position, etc.

Keeps going off every 15 minutes then showing no signal

Please check if the fan filter is clogged or the lamp heat is too much. If so the lamp can shut off, so use a good cooling fan to see if the shut down stops, if not the projector power or the lamp circuit must be checked for a loose connection., or possible power supply load breakdown.

Last week, I spilled the coffee. I get zero power after a week of drying out. I've used the power supply, and the battery, and no power at all. I have read that cleaning the motherboard may help, but I...

If you aren't knowledgeable in disassembling a laptop, then I would encourage you to take it or send it to a computer shop. I usually charge $110 - $130 to do this type of repair\servicing. I've had lots of customers who've done the same thing you did, and then try to take apart their laptop to clean\repair it. They almost always end up breaking something; which ends up costing them more for me to buy the part, fix it, and re-assemble the entire thing. If you decide to do this on your own, then be sure that you have something that you can keep all of the little screws in and have them labeled so that you know where they go when you put the computer back together. More than likely your laptop is going to need an new motherboard put in it. You can expect that to run you at least $250. -madhatter639

I have replaced the mobo in my dv6000 and still have the same issue. power sometimes comes on for a second or two. Power supply is generic but output is pretty close to spec...within .25 vdc. Should I...

It is highly unlikely that the it is your mobo since you saw the same problem. I would try to find another power supply before doing anything about the processor. Some times DC power supplies are defective either because can't handle the load(amperage pulls it down) or there is a breakdown where it lets through some of the AC component. You would need a oscilloscope to see the AC component. Just try to swap it out with another that has the same specs.
If it still gives you problems, the only thing left is the processor.

My r3000 has a tempermental power supply. it

whatabout the lead that plugs into the laptop ? does the plug in the laptop move easily, with the lead in, Sounds like the actual plug in the laptop is breaking away, the solder around the connector. Sadly to fix that you will have to get it repaired for about £50 to £70, maybe more ?? please make sure the lead from power supply is not loose or a bad fitting.

Sounds like a thermal breakdown of a componet. it could be in the main power supply regulaor supply or even a bad capacitor in the power or sweep supply. In some cases Zener diodes can break down and change values after warm up. In some cases also bad solder connections in the highvoltage section, or the power supply can cause this problem. It is a hard call without being able to look at the set. Just a few leads on where to go first. most likly a combo unit, such as this one , would cost you more then a new one these days. Good Luck PS Please dont forget to rate this thread.
