Hi, I found an LG Flatron 795FT plus monitor...after checking and replacing one diode and one mosfet I measured infinite resistance on the CRT filament pins...I think it would be not possible that all the 3 RGB filaments had broken, but in effect if I try to power the pins i see 0 Amps with an ammeter...
Is there someone that found the same fault??? Is it possible that a CRT deads in this way??? Thanks.

Yes, it's quite possible that the heater filaments have gone open circuit, It doesn't happen often - but it happens. If you're sure you are measuring the correct pins, then the CRT is useless. Sorry!

Most CRTs wire the heaters in series. The only one I've seen with a single heater out was a 70's Sony. Andy Cuffe

Hi, tnx for reply. I've looked into the bulb and i think the filaments are in parallel....I ask: may be an open interconnection on the CRT pins???
Thanks. Marco
