You're not supposed to repair! You're supposed to throw away, preferably in a way the prevents recycling, and then buy something new! This is not 1930 or 1945 any more We are a use-once-and-throw-away society now. I bet even your mattresses still have the original tags on them.

> The plague continues.
This time it a Westinghouse LCD monitor/TV, apparently made in 2006.
1000 µF 356 µF
1000 µF 289 µF
220 µF 427 pF
220 µF 537 pF
This time the symptoms were a backlight that would not turn on,
and when the when the power was plugged in,
I could hear high frequency squealing for a while.
Also, if the backlight brightness was reduced,
it would flicker erratically and there was squealing
corresponding to the flicker. So I thought,
Ahah! it must be related to the high voltage power supply
(inverter) for the flourescent tube backlight,
and that's where I found the bad caps.
I replaced the four bulged caps. Now it works fine.
