Heres a few circuits you may find useful......you have a 12-0-12v ac transformer.....you can either not use your center tap(black wire) and you should have 24v ac across the two other leads(yellow),between any single yellow and your center tap you will have 12v ac(use your meter to check).you...
heres some info on what is needed to reinstall/update software on most lg lcds........its not a job to do unless you know exactly what you are doing....
let us be very clear on this subject.....as far as testing the mag in a mw goes-the check of continuity between filament pins to case(sc mag-scrap buy a replacement magnetron) will isolate a faulty mag....be very careful about removing the filament wires as the hi voltage capacitor may still be...
its for testing hi voltage diodes,asm rectifiers and a functional capacitor test-(found in microwaves).......when testing a diode if its ok one led will be lit(depending which way round your diodes connected )if both leds light the diodes sc,no leds the diodes oc.......ive been using it for...
this is a driver that ive been using over the years for many different things and its posted here just for info purposes really,theres no reason as to why the fet could be direct driven from a 555........
i have been in the trade for a good 20 years or so now.....if u have a set with a particular fault let me know here or **broken link removed** or
**broken link removed**........
i found it stops erratic fet switching which was sometimes a problem (electrical noise)have used this schematic for years with no problems and it works well
