Weak signal receive of ic2100h

The reference would not prevent you from receiving. It is more likely that the pin diodes in the antenna TX/RX switch are defective or the RX front end amplifier is shot. Check the diodes with an ohm meter. If you get a short across one, check with the leads reversed. if you still get a short, then the diode is most likely shot. Make sure you have the schematic to follow. You can get it at

No picture when powering on tv want to fix myself

If you don't see any lights on the panel, It could be a busted fuse. But usually based on my experience in fixing TV's (whether CRT or LCD) if the fuse was indeed busted, It only means that there's a short circuit somewhere along the circuitry. It may be a shorted power regulator (which is usually the case) or an open diode or resistor.

But try plugging the cord to another wall socket first or replacing the power cord (if possible). If none of them work, don't try to open and fix it yourself. Even with the power cord unplugged, you can still get a shock which might lead to a more serious injury.

Bottomline, Don't try it to fix it If you don't even know how to pronounce the word "diode"

(Remember that electricity is invicible. And what you can't see, can kill you)

Whirlpool oven

Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.

Hi, Battery light coming on occassionally. Battery is new. Any ideas, could the alternator need new brushes or rectifier? Thanks

i think you are right...the alternator may need a new set of brushes. battery light coming on and off is an indication.

a busted rectifier would not indicate an on and off light but rather a steady on light. but it has 6 diodes and one busted diode would do the same. on and off battery light depending on the load present in the system.

tnx 4 using fixya,

If you can open the cover of your monitor try to locate the fuse maybe the fuse is busted replace it.
if the fuse is blown or busted again there is short circuit in your power supply maybe the diode or the power transistor is shorted you need this to bring to the shop for services
