Open lcd 17 power supply 5volte ok 13 dimming


Hello.
First of all you need some electronic repair experiance,
You have to disconect all f the power supply that going on 5v(rgb processor in moust cases)and 13v in most cases ccfl inverter(back lite ) with his driver.than have to mesure the voltages.
-Replace the capatitors in 13v line.
if the problem persist try to replace the diode one for 13v with one for 5v,they should be the same type.and check the voltage 5v and 13v.
if the problem is still on 13v look for the problem on the 13v line.

My Cerwin vega xls 15s doesn`t work!


Blown circuit. The question is; was it the power supply that blew out or was it the amp? check for fuses and see if they are ok. If they are not, replace them. IF they are then you are going to have to get new amp and or power supply.

What will happen if inserted the 110v input d-link wireless router power supply to a 220v outlet? does my router busted or just the power supply?


Most likely you have damaged not only the power supply but also the D-Link wireless router unless the power adapter is a multi-voltage power adapter. Check the label on the power adapter and if the input voltage is a fixed 110 volt power supply you are in trouble.
You can try getting a 110v power adapter and connect it into the D-Link and if it works then you are lucky.

I plugged my korg 61 keys workstation directly on 220v instead of 110v, of course it is no longer working. what do I do?


Since your synthesizer uses an external 12v power supply your system should be OK, Replace the power supply with one rated at the following specs.
Power Supply: DC12V, 700mA (AC adapter)

I hope this helps.

Using dryer in 220V country


There are two systems in use in the states
110v dryers are available that fit a standard 11v 15a socket
110/220v fit the oversize 'dryer' sockets, and they are two 110v phases 90 degreees apart
the motor runs of a single phase 110v.
there is 220v between the 'outside', the active lines of the two phases, at any time, but it is not useable to provide mechanical power as a single service, due to the complicated shape of the wave form when you add out of phase voltages together, but is ok to drive the heaters, they have no mechanical efficiency requirement
A 2 phase 110v heater it means 3kw can be supplied without a 30 amp circuit
but it becomes difficult to use a single phase 220-240v transformer to provide 2x110v 90degree 2 phase current unless you specially buy one in. .
High power applications in 220-240v are generally supplied by 415v 3 phase 60deg supplies,

Any transformer would be onsellable at the end of your posting, to your replacement, who would doubtless be in the same boat as you, with a heap of 'stuff' that needs to run.

UK Aus NZ may be sources of transformers, or dryers to suit.
check with Australian UK NZ suppliers as well as local Indian ones, as those countries are also nominal 240v single phase home suplies and they may have (1) the dryer, or (2)the transformer to suit the 110 2 phase dryer

Boot failure


samuel,
if you don't here ok beep or any error beep:
  1. First check out speaker is connected properly to motherboard.
  2. Remove all component from motherboard like HDD,FDD, RAM etc..
  3. Just put only processor to your board and power-up
  4. There must be a long beep for missing RAM, if not means you have problem in Motherboard or CPU. Try out another board and another CPU to find out which one is faulty.
  5. If you got missing RAM beep, then power-off and add RAM. Then power-up there must be ok beep (only one beep) or missing RAM beep. If missing RAM beep, then your RAM might be faulty try to clean the connection point with pencil earaser and try out again. If no success then try with another RAM.

I think this will help you.
Please post your feed-back. Or ask me if any question.....
Gud luck
