HT-767
Doesn't power on, nothing happens.
Remove rubber feet if any and unscrew case.
First look on the inside. At least one wire has broke off from the power button.
Unplug cables and remember where they were. Unscrew 6 screwes to take out motherboard.
Soldered wire back to power switch. Still not working.
I plugged in powersupply and measured voltages from this 5V regulator.
9V went in but 5V didn't come out so it seems that voltage regulator was broken.
Off with the old and new 5V regulator in it's place.
Don't forget to use thermal creace or something similar.
Success. Another Famicom clone works again.
