David,

I checked:
*Red tube filament is on. (all are) Only blue & green guns are
shooting.
*Board is warm like the rest. (ceramic resistors)
*Red - Board is secure.

Video amp for this TV is a TDA 8177 $4.95 online.

Quoted from manual********
No Regulator Output and a ***Chirping Sound***
1) Usually indicates excessive load.
2) Check each of the secondary supplies for excessive current drain
(the 110V supply load is the most likely cause).
*********************
We heard a few beeps over the last week... could have been a "chirp"
which is the HV control? Athough why would only red go out???

Also think of any IC that may have overheated since this unit assembled
in Mexico had poor installation of thermal grease on the STK's that
failed... - grease on board not heatsink -

Thoughts - Glen

FAR LEFT TUBE. Chanmces are if you have filiment on the othe tube and
not he read tube there is NOTHING wrong with your supplies/ Try
whiggling the read crt board around , and see if filiment will come back
on , if it is not there.. If it is there and still have no read the,
replace the video amp ic on the crt board i think it is a TDA 6111
Good Luck
