I have a Phonic Helix Board 24 firewire MK2 When i open it all the peak led stays open I think the power suply is busted I need an expert


The power supply uses three, 3 terminal regulator chips. You should find +/- 15 volts and +5 volts DC from those. There are two fuses, one for each polarity. If one of those is blown, that would cause the problem and one would need to find WHY it blew before replacing it.
You need to find a competent electronics repair person.

2003 Silverado one ton shows -11.7 volts at brake lamp connections. Truck light work ok but the trailer brke light are leds and they don't handle the -11.7 volts.


Hello! Place a 1/4 watt, 50 ohm resistor in series with the +12 battery feed to the trailer LED brake lights...Each LED drops 3.6 Volts...You can run a maximum of 3 LED's per resistor...If you have more than 3 LED's run them in parallel with each set of 3...Each run of 3 requires it's own 50 ohm resistor...

ViewSonic N3250W Television with FSP212-3F01.dead needs VOODOO


I am working on the same power supply right now, my has a bunch of bad caps that I already replaced but I did not try to turn it on yet becuase I see that RS1 and RS8 are missing, some one had try to fix this power supply. Can you please tell me the value of these two resistors? Please see my pictures at http://s807.photobucket.com/home/budm/allalbums
Your problem sound like the logic board problem, I can tell you what you should have if I can find out if these two resistors were left out from the factory or some had removed them. I fixed the same power supply for the N2652 but I did not take the pictures of the board, I wish I did.3a99fcd.jpg

I have a ViewSonic N3250W Television with FSP212-3F01 power supply. The power supply looks OK no visible caps problems no burn signs. I get the 5 Volts output OK but not the 12 Volts or 24 volts. The red...


Does the LED kick on when you push the power button or when you apply power? Typically, the 5volts will run the microprocessor and that looks for a command (power button). When it sees a command, it will send a signal to the power supply to kick that on.. so at this point, you want to look for that signal. If you push power and no power on (p_on) signal goes to the supply, its likely your main board.. but if it does, and the supply doesn't react, then maybe its the power supply. I am not totally familiar with this tv, but thats how all of them really work. Even if the caps look good, some could be bad.. look for brands like "capXon, sanXon" are typically the defective ones, theres another but its slipping my mind.. usually 1000uf @ 16v are bad, or 2200uf @ 10v are also common.. you can search the value and the little code, usually like C9M or something and see if that batch has known issues..
let me know what you find, or how I can help

Do you have a diagram that would show me step by step how to install the new power suply I bought for my computer.


Their is really no diagram to show you how to hook up your supply.
You only have a hand full of plugin connections.
Your 24 pin connection to the mother board, you may or may not have a 4 pin 12 volt video connector, which has to be connected if on the board., and your fan connections.
Everything else is controled thru the motherboard.

Timer not working Malibu ML88T Power pack


there are multipul 12 timers on the market BUT if you use a 12 volt power pack designed for a car radio display or even a simple 12v 5 amp laptop power suply and a cheep outdoor timer or cheeper indoor timer and run wires inside you can add lights
remember theise lights are low voltage and if you change the bulbs out you can really strech out the amprage too
low amp led automotive bulbs are a great invention they draw mili amps and use 12 volts
i converted my noma moonrays to a laptop power supply and added 30 more to a single string so i curently have 50 lights on 1 power suply pulling aprox 4.5 amps out of a 5A power supply i used led bulbs and simple moma cord now i can light the whole back yard with 1 ps and it's really bright if i use the led headlamps mounted under the soffit on the house
