Once the caps blow they usually take out the driver ic too. check across your power to the amp with ohmmeter when you find the issue it will drop to around 20 ohms in one direction.

There must be a diode that is faulty in the power supply section mainly on of the rectifying diodes. If you look closely at your board you will see four diodes that just after the fuse and befroe the Big capaictor(filter cap.) One of these four diodes must be faulty as the fuse keeps blowing. the diodes are responsible of current limitation drawback. So there must be current flowing back to the fuse that makes it keep blowing. Check and replace. Good luck Thanks for using Fixya.
dis-connect wiper motor and replace fuse and try switching wiper motor on if fuse does not blow motor faulty and shorting out and causing fuse to blow.if still blows fuse must be a short in the wiring from wiper motor plug back to wiper motor switch.
Your element will be faulty. Remove both wires off the element. tape them up. Select the program that blowa the fuse and run. If not blowing, replace element.
if you keep blowing a fuse there's a good chance it's not a faulty part but a short in the main harness most likely under the dash where all the connectors tend to get brittle over time and short out constantly. also check the ecm connection there is a 60 pin type.
the poer supply faulty. Isolate Horizontal output stage from the power supply and connect dummy load (like normal bulb same wattage as TV ) and test. before that pls check all component in power supply and replace and burnt parts spacialy diodes caps and power regulater ic as well
DONT WASTE YOUR TIME AND MONEY THE PCB(POWER CONTROL BOARD IS BAD YOU WILL BE BETTER OFF BUYING A NEW MONITOR)
IF you do find the power control board replacement and get it to work i think you would have better results spending the same amount of money on a new monitor with all new parts plus warranty
Hi,
I have exactly the same problem, where do I find the Capacitor and driver IC to replace?
