So turning on the computer doesn't bring the monitor out of standby? Just to be sure, try turning the monitor off, then on again and the Pc on at the same time. If you see any writing on the screen, that will be good news. Make sure it isn't just the cable to the monitor. It is possible to mess up the connector on the cable where it goes into the computer. If one of the pins is bent, use tweezers, to very carefully try to bend it back. If it breaks you have a big problem - have to find another one and splice it onto the cable or replace the whole cord. Still nothing on the screen. Could be the monitor. Could be the video card, the motherboard, the microprocessor or the power supply. The worst case is that the old power supply failed drastically and destroyed all of the above. Try your monitor on another computer. Any sounds coming from the computer when it starts? Startup music would be a very good sign - most everything working. Any beeps? Three beeps mean the video card has failed but the motherboard and processor are probably okay. I can't think of an easy way for you to test the motherboard and processor. If you have access to a similar computer, you could try swapping in a known to be good video card. It sure looks like the worst case scenario.

    It could be just mixed up CMOS settings.
    I can't find how to clear the CMOS settings on that computer, but taking the battery out for a few days will do it. Then it might start okay!

Hitachi 1350 projector dead, no power. cleaned everywhere, changed the bulb, nothing I do gets power into it.


I assume the projectors are of similar age and have similar useage history? Not certain why they would fail together, but the most probable cause is faulty switch mode power supplies. The electrolytic capacitors in these supplies a relatively short working life, especially when installed in high temperature environments - like a video projector. new caps in the supplies may be all that's required to solve the issue. If you have other similar projectors, they may well be approaching the same problem.

Any reasonably competent TV repair tech should be able to check the supplies for you, and repair them if found faulty :o)

sounds like your power supply is having trouble. Is the inside filled with dust bunnies? Get some canned air and blow out the inside of the machine. Make sure all the fans spin freely. Once in a while the video card will need to be pulled out and reseated to reestabilish electrical connection. At the least, clean and replug... at the most, a new power supply.

No power to system but green light on motherboard is on


If you have replaced the power supply with a known working power supply and have connected it properly to the motherboard and all devices, then you probably have a bad motherboard.

remove all the ram from motherboard and switch on the system and see it is working or not like just on and fan are rotating and the smps fan is also working and your system is giving beep sound for ram.try with other smps also some time problem with power supply also. Remove the connector of power switch and restart switch and directly try to on from shorting the connector with the help of pen or screw driver point. Some time faulty switch also give problem. Just try all these possibilities.

Hope this helps. Please rate my response.
Thanks.
Have a good day.

Smart Cycle. Worked Fine yesterday. Changed the batteries, Connections are tight. Turn it on, Nothing No lights on the cycle , nothing on the tv screen.. Other toys work well on the same TV. Help


do you know where you put the cartridge in below where you placed the 4 screws you can take those apart and you will see some cables inside you will see a red and back one together thats the power from the batteries below. i cut mine and drilled a hole on the side where my son wouldnt hit the cable and now my smart cycle doesn't use batteries it uses the power in my house to power it. i used a 4.5 volt 350 mA power supply for some other deal. i had laying around.
you can use 6volt power supply and that will work i wouldnt go higher than 6 volts since 4 D batteries add up to 6 volts 1.5 x 4 = 6 volts. the watts doest really matter since the device will use what it needs.
black cable on power supply goes to red on bike black and white cable on power supply goes to black cable on bike
at least thats how it worked on mine it didnt hurt my bike i had to switch the cables around i didnt have the polarity right the first try.

No power up A135-S2266


Maybe your graphics card and/or display went bad. If I were both of you, I would check that out and see. if so, then you would have to buy a new computer screen for your computers.

Latitude C640 is dead!!


The only solution that I can think of would be a power jack problem. I would not advise replacing the power jack yourself since you have to take out the laptop mother board, de-solder the power jack then solder the new one on and put it back together. My advice would be to take it to a professional computer repair shop and have them take a look at it and replace the power jack. It is worth getting repaired since power jacks usually range $40-$70.

Check that all the power supply units are switched on( Wall Plug, UPS, CPU), If all is ok and the problem exists, replace the CMOS battery.( if the sys works replace your CMOS Battery, configure the cmos settings also)
