Picked up this off brand 26" LCD TV on garbage day, yeah, I'm a picker; first LCD I've seen in the trash. All over the internet it says the switching PS craps out and all the electrolytics have to be replaced. Anybody ever do one of these?
Easy. Just make sure your desoldering iron is hot enough to heat *all* layers of the circuit board. Most boards are multi layered these days with layers of circuit traces sandwiched in the middle of the board. Make sure not to burn/overheat the traces as they can lift off the board making your job a little more difficult.
Replace ALL the electrolytics, not just ones that "look" bad, otherewise you'll be going in for another repair in short order.
For suppliers, don't bother going to Radioshack. They're useless as the current administration in washington. Try Digi-Key, Allied Electronics, or Mouser Electronics. You'll have to do some searching and number-checking, but if one or all three don't have your parts, nobody does. One other place to check is MCM Electronics... they MAY have complete rebuild kits for SMPSs, although it can be a crap-shoot.
Otherwise, it should be simple if the power supply is all it is.
One last word of caution (trust me on this one!); when you think you have it fixed, even if you think it's still broken DON'T TOUCH THE CCFL INVERTER WHILE IT'S GOT POWER GOING TO IT! The inverter steps the voltage up past 600, 1000, or 3000 Volts. If you accidentally touch it you'll know!
