I've just saved this TV from a journey to a skip (or possibly just delayed it a bit?) .
The fault in simple terms is - no picture, no sound except slight audible whistle from a switcher somewhere and the status led goes between Red (standby) and off - should be green for on i believe.
So far I've checked all the caps (except for some real tiny ones), all the diodes and all the transisters on the psu board - which is a PLCD 190 C1 type.
I have the service manual for it (LC4.31E AB) though it's a bit lacking in info for the 32" version and some bit are innacurate like the block diagram - it's close but no cigar.
the outputs of the psu board seem OK. and 'some' of the other supplies generated on the SSB & IBO Zapper board again seem OK. ]#
Short of measuring everything i'm a bit stuck.
Anyone had any dealings with this set?
