Screw Panasonic parts research. Called them three times
and they won't call back. Anyone replaced these associated
with the green convergence?
R7048, 49, 50, 51 ? (near the four wire plug going to the green crt)

They've all had the paint burned off but measure 98.5 ohms each.
Something I've worked on in the past but I can't recall what says these
should be 10 ohms?

Only problem with the set is the green convergence is off by an inch or so
so I thought I'd replace the STK devices and of course the resistors that
were hot.

Default Panasonic PT-51DX80A serviceman mode ?

Get the service manual. Negotiating the panasonic service mode is a PITA
without it.

Default Panasonic PT-51DX80A serviceman mode ?

1.. Select SET-UP icon and select CABLE mode.

2.. Select TIMER icon and set SLEEP time for 30 Min.

3.. Press "ACTION" then VOL up to exit menus.

4.. Tune to the Channel 124.

5.. Adjust VOLUME to minimum (0).

6.. Press VOL ? (decrease) on receiver. Red "CHK" appears in upper corner.

To toggle between aging and service modes:

While the "CHK" is displayed on the left top corner of the CRT, pressing
"ACTION" and "VOL" UP on the TV simultaneously will toggle between the
modes. Red "CHK" for servicemode and yellow "CHK" for aging.

7.. Press POWER on the remote control to display the service adjustment
modes menu, select adjustment by pressing the VOL right/left buttons and CH
up/down buttons on the remote and ACTION to enter the adjustment.

Don't have that manual handy, but this is from another.

I have the excerpt from the service manual regarding nagivating the menus.
I just need an accurate list of steps to enter it.
