Kef htb2 subwoofer not working plug fuse ok sub fuse ok is there an internal fuse

If you have external fuse there will be none internally. Chances are you have blown the amp if power is confirmed to be getting into the unit and there is no sound.

My digital tv wont come on even tho standby light keeps flashing would it be the internal fuse blown

No, if an internal fuse were blown, you would not have a flashing standby. Most likely you have a problem with the power supply but it could also be with inverter or driver circuits.
If it's a good set, take it in for repairs - if it's a cheapo, trash it!

Microwave is NOT coming on. I have checked the circuit breaker which is fine. I also disconnected power and conected back


The most likely cause is an internal fuse which has blown. This can be replaced with a fuse of the same volt/ampere rating. Note that a blown internal fuse is most likely due to a fault on the oven's power circuit and further inspection may be neccessary.

Please feel free to contact me for any further assistance.

Internal Control Module Keep Alive Memory (KAM)

P0603 means Internal Control Module Keep Alive Memory (KAM) Error

In other words, that code is set when the PCM loses "keep alive" memory B+.

This code can also be set if the batteries went dead at some point, but mainly it means there is an open circuit detected in the KAM circuit.

On a '97 F-250, check for a 5 amp fuse blown in fuse cavity #2. If the fuse is blown, check for and repair the short-to-ground in circuit #729 (red with white coloured wire).

Good luck dear.
