Sony Trinitron KV-1921

[Alastair E]

Reading the above suggests the USA versions of these period Sony sets with GCS/GTO's were more reliable than the UK KV1810....

Here, you could meticulously repair an 1810 according to Sony's own service-kit and two weeks later get the set back--All blown out again and with an irate customer to boot! They quickly gained the terrible reputation they have for being near unrepairable. Many places refused to even touch one, even if it wasn't dead.

--The UK sets--Really Were an absolute Abortion, they would blow with no warning and for no apparent reason, no surges, no lightning-strikes, they just died, leaving the customer facing huge bills.

Even Sony UK had issues with them at the time I gather.

--If you're lucky and have a worker--Do as suggested above--Re-cap etc, keep the SG, but if like here in UK you cant get any SG's these days cheaply--Then why not replace and modify--Its Hardly a 'Mutilation' or Major Surgery, merely the substitution of a drive Tx maybe the Drive transistor too, and some passive components, Take you less than half-hour once you thunk it through.....

Does the USA KV1921 set have a SG in both the PSU And in the Line stage, like the KV1810UB British Sony set,--ie, Two of 'em per set....?
