Magnavox: 27Z101Repeatedly blowing HOT

[Michael Webster]

I have a 27" Magnavox that came in dead.. replaced Horizontal Output
Transistor and its been awhile but might have replaced the vertical ic
also.. set will run fine with all tv functions only the Horizontal Output
Transistor gets way too hot to touch and eventually breaks down.. Any help
on this would be greatly appreciate. Also if someone could tell me the
original horizontal output transistor or one that would work in this set
thanks..

130 Volt supply too high, IFT going bad, something in the
pincushion or IFT secondary side drawing too much current
(like vertical).

Most likely part number, for sets with diode modulator or
pincushion board is 4835 130 47897, probably was S2055AF
or BU2508DF.

Sets without diode modulator or pincushion board could take
4835 130 47771, which might be a 2SD1556.
