Thank you for the reply. But how do I test them. Voltage meter? What I read online they were talking about stripping the wires to test... I guess I could go back to the guy as it was a phone conversat...
Greetings Scott welcome to the Forum.
You mean you checked the HiVoltage, and it was ok?
Did you check the Control Voltage too, Stats can click and still not have power to turn the system on. F...

It is possible that the second inverter is defective or there is no supply voltage going into the inverter. A +12V supply is usually used for backlight inverters for la...

Hi Rhodygirl,
There may be no high voltage going to the crt's or no signal going to the video driver.
Must be some wires or connectors got loose. If the problem is a cold solder on the defl...

Hello Seilee1, welcome to the forum. Since it will be guess-work as to the voltage I strongly advise you to ask the only ones who can know and those are Amstrad themselves. Since your profile doesn&...
I have this Epson Stylus Photo R300

coming out is 1.7 volts which I...
start the car and tell me what the voltage reading is if its less then 13-14 volts then either the alternator is faulty or the wiring is bad on the alternator. try cleaning the contacts on the wires a...

Amongst the various laws of physics and electronics, power is the product of voltage and current. Hence, 5 volts at 500 mA will yield just shy of 2.5 watts. My coffee cup warmer draws about 17 watts...
