The suspicious 400mA fuse removed for closer inpection.
Checked out the power supply board. Generally everything looks pretty good. No shorts or burnt marks.. No leaking or bloated caps.. resistors still visually acceptable...
One of the quickblow fuse (400mA) looks suspicious. Supposed to be clear and the glass casing looks cloudy.. closer inspection after removal revealed that it's blown. I have a 315mA spare, put it in and rotated the rotary power switch to ON, it did worked for a short while (the motor spindle spins!) then it blew! Aaarghhh! sux!
2 things came to mind:
1. fuse rating too low
2. fearing the worst: something seriously wrong with circuits downstream of the fuse.
Need to get 400mA fuse or higher rating...
stay tune...
