pyesetz | LCD monitor repair

Finally got that spare part! So now I can install it, with assistance from Kid #2. Photos below:

Here is Wifey’s LCD monitor, in the form it’s been in since I took it apart on June 19th.

Upper right: LCD module.

Upper left: back cover.

Lower left: circuit guts.

Lower right: everything else (front bezel, stand, and a baggie of screws, screw covers, and the circuit board for the front-panel buttons).

Close-up of the circuit guts. In this photo, the circuit board on the left side of the previous picture has been flipped over so you can see the components on its underside.

I’ve been waiting for this envelope for weeks! It finally arrived.

This is the object that was inside the envelope. Although this photo is the same size as the preceding one, the envelope is actually 5x bigger than the capacitor that was inside it.

Extreme close-up of the old capacitor, in situ. Unfortunately, you cannot see in this picture that there is a great big wad of a taffy-like substance underneath it, gluing it down. Apparently the manufacturer was very concerned about this part possibly bouncing around on its wires during shipping. I sliced through the taffy using a screwdriver.

Replacement capacitor has been installed! At the top of this photo, you can see another gob of that white taffy-like substance.

Super extreme close-up of the circuit board underneath the replaced capacitor (named CB04), showing my solder joints. The burn marks on the board indicate that I am not very good at this!

I have no idea whether this circuit board was made using the new “RoHS” solder. All I have is the same solder spool that I’ve been using since the 1970’s, which is full of hazardous, poisonous lead, but it works very well.

Fully reassembled unit. Looks like new… unless you peer carefully at the black dig-marks on the black background where I had trouble prying the front bezel apart from the back cover.

And the result of the repair was No change. Monitor still goes black after one second. Tried plugging it into my laptop: displays properly for one second after plugging in, then goes black. Oh well.
