[dacflyer]

i got a panasonic tv here kicking my butt,, its something simple but i cannot find the bad cap...<p>tv is a model ct-27sir or s1r?<p>anway... i got severe foldover at top of screen.. replaced a few suspect caps,, still no good...
anyone know which one it is?
usually older set had a low Uf and a high volt rating... i cannot find such of one in this set
please advise,,

heres some more... is it possible that the vertical amp could be causing the foldover?
i have replaced every cap in the area of this ic...what gives,, never had a tv kick my butt like this before,,,<p>also, is there a tv repair forum thats free? or are they all pay sites?

As per your query on the Punysonic 27S1R..circa '93. Considering that you are sure of
the LA7836 and its associated caps, (particularly the C455-100ufd) pump up cap and
that chips support caps have either been replaced or ESR'D. Why not move over to a
ancillary portion of the associated vert circuitry that you might not have suspected.
E.G.,the acl circuitry of IC 101/AN5163 and the two, Q451 and q452, vert blnk xstrs.
Seems that circuitry gets its B+ from a sweep derived supply off pin 1 of the fly and
I think that by failure analysis you are going to find that the 225v filter cap,C555-(100ufd@250vdc)*** has been hammered by those recurrent 15,750's squares and
has ESR'd down to the tenths of ufd's in value now.
Addenda:*** C555 (22ufd@250vdc) alternate value also.<p>73's de Edd
