Sylvania (Funai) TV 6420FE Goes Off a Second After Turned On

[Brad]

Hi,

This "TV" doesn't have a "mode switch". This is NOT
a TV/VCR combo.

I have a Sylvania (Funai) TV model 6420FE (mfg 01/05) in
my shop. Note: I do not have a SM for this set.

The TV goes off about a second after it is turned on. There
is HV and the regulated B+ goes to +115V at turn on. There
is vertical deflection based on the "buzz" sound I "picked up"
near the yoke. I removed the H.O.T. and used a 250 ohm 200W "dummy
load" accross the regulated B+ with the same results (TV goes off).

Anyone fix one of these with the same symptom?

Thanks in advance, Brad

Mains switch ?
look for any shorted diodes in the vicinty of the LOPTX- could be
something drawing excess current. check vertical and rgb lines. Also
check any data/clk lines aren't broken - also, the micro or eeprom may
be the problem.
