61uwx10ba. no power to any boards but power supply.


have you reched around the new soldering area carefully, check for solder spills or drops in the printed circuit, also another thing to look for is some of those replacement stk do not hold their weight, you might want to take them out and try the old ones to see if you recover tv power.

Hitachi 60ux54b/55k--no sound


For starters, remove the back cover and turn on the TV. You should see 8 green LEDs on the circuit board.

You may have lost power for the audio amplifiers.

Power button makes a click, click sound


The sound is coming from a failed flyback auto transformer. You will need to replace that.

TV Won't Turn ON


Are you getting any response when it 'doesn't turn on' like can you hear the fans spooling or anything? I would begin with verifying all the grounds are properly secure especially the lamp switch cable this can become loose possibly causing there not to be a good ground I've seen it happen on vivitek TV's Verify the TV is OFF and unplugged before you touch anything check the grounds and verify what you can see is properly set. If everything looks ok, check to see if theres a lot of dust in the fans and so fourth, and if not that then replace the power supply.
