Not normally, At only seen 1 and that wast the MX0541 variant. Most of the
time in that situation Will try it and see if it blows up.Supose it could
have been some type of surge....

Does the MX0841 fail all by itself? All other parts check good.

Never have, The orentation of the transitors in the MX0841 is not the
same
as 2 transistors side by side, one is rotated (would need to look at the
schematic to tell you which one) and I think that they also contain the
MOV's too on the substaright, but no data is avalible on the MX0841 as
to
ratings. So it might work but could be a mess to reengineer. I Usually
just
replace the MX and check C609, C610 ( a couple of brown-maroon caps .47
@
50V.they at times short/fail and wipe out the new MX,) Check also the
HOT
and driver connections and check the 200V supply for shorts at the CRT
board
and replace the fusable resistor for the power supply

This is the first Sony TV with this hybrid transistor IC. Has anyone
tried using the 2 old transistors, C4834 in place of it?
