This will be a short simple post. I bought this monitor (22 inch LCD Westinghouse LCM-22w2) back in June for $20 after my monitor died. It worked fine except for one problem: when the monitor went into ascreen saver mode, the screen turned white (instead of black). Some people called it white screen of death. The guy I bought it from said that it was a capacitor problem, but who knows?
When the white screen started to bother me, I opened up the back of the monitor. The towel on the table protects the screen.
Take the metal box out to get to circuit boards.
They sell capacitor kits that have all the capacitors, but in my case I could see that only three capacitors were bad. Three circles in the picture above shows those capacitors (each one 220 uF, 25 Volts). It was easy to see that they were bad because they were bulging at the top. All the others were perfectly flat.
Here is a picture after the three capacitors are replaced. I put in 220 mF, 50 Volt capacitors recovered from a broken TV. 50 Volts gives better safety margin.
Here is a close up picture of the three 220 uF (bulging) capacitors. It took me less than an hour to get this done. If I knew it would be this easy, I would have done this long time ago.
