Fix that LCD Flat Panel Monitor

HOW-TO:

Fix a faulty LCD Monitor Power Supply

Problem: You have a LCD monitor that either does not turn on or turns

on and off randomly. There might even be a high pitch squeal when it

is on.

Solution: Replace the power supply of the monitor.

Options:

1) get a new monitor (cost: too much)

2) get a new power supply (cost: too much, that is, if you can even

find one)

3) FIX IT YOURSELF (cost: FREE)

I will show you how easy it is to fix it with the scrap parts you

already have.

I received a FREE lcd monitor (remember the cost) that would turn on

but after 15 minutes or so would turn back off and would not turn on

unless it was unplugged then plugged back in. After opening it up, I

noticed there was a bad capacitor on the power supply. So I dug

through all my spare components to find an identical (rated)

capacitor.

When I got it changed out and powered back on, it still had a high

pitch squeal and random power problems. So I just replaced the whole

power supply.

The power supply of the monitor had 6 connections. 3 ground, 2 12volt

and 1 5volt. I have several old computer power supplies, so I used one

of them (cost: Free)

All I had to do was strip it down to what I needed.

Next I mounted the PS on the back of the monitor. Using the existing

mounting points (for wall mount) Make some custom connections (cost:

Free), so the monitor can easily be taking apart.
