Samsung LE37A656A1F goes to white screen after 2 minutes!

Hi Bruce,

You're perfectly right as ever, and I avoided having a go 'till I had a whole pile of duff ones to practice on, as new Sony ones are pretty cheap from China, though 'Sammies' sadly aren't.

Didn't much like the idea of hot air gun and tape, though with experience guess it's the quickest way. I currently use liquid flux and solder wick then lift each pin, mind you, all 48 pins take a minute or two.

Clean the board, use a spot of 'super glue' to hold new chip in position - Have a minute or two to get it right B4 the glue sets. Flood area with flux and try 'drag solder' then clean up with solder wick.

First time I tried it, discovered 6 shorted pins on a pin-to-pin check, where could see no solder bridges with the USB microscope - Second one was exactly the same, so hopeful - Chris.

Hi Chris,

Is that what they call British ingenuity? Way too gentle for us colonials. We just heat the IC until you can flip it off with a pointy thing.

Hi Bruce,

Guess you're right, but some of us Brits do things just a pin at a time, as when we go in full force, troubles always ensue.

Guess we're doing the same currently, with the odd bomb here and there.

Suspect outcome dubious, as ever.

Glad just try sort T-Cons - Only faith to try sort 'em - Chris.
