Title: Fixed Toshiba 20WL56B
Post by: buffy on January 04, 2009,12:39:38

At last the Tosh is fixed  :clap:  :clap:  :cheesy1:  :shout: its taken 4 - 5 months..... but i had 2 boards, one has the osd/menu fault (unfixable) god knows, i suspect the controller chip....  The other was the picture breaking up moving - which was traced (by accident) to Q101 a tiny, tiny mosfet chip, getting VERY hot, it was shorted internally!!!  I got myself a T0220 QFET FQP06 from bits box, well its a mosfet!!! the FET chip was only switching DC volts.... and IT WORKS!!!!!!!!!!  :dance: :dance:  right bodge fitting it though... used veroboard to isolate the Transistor from the chassis.. held the thing down with silver tape, IT WORKS!!!! now i just need a remote!!!

Sorry if I appear ignorant, but what does IOM mean in this context?

That's the only definition of IOM I could think of, (other than Intitute Of Management), but could see how either fitted in this context. I was trying to think of some technical phrase, and thinking have I not learned anything in 24 yrs of electronics?!!!!

My faith is restored.... thanks..
