Replaced STK392s, now can't access convergence adjustment
First, this is a great forum and I appreciate all the help I've gotten from past threads. I've tried to use the search function as much as possible to avoid asking something that has been asked before.
I have a Toshiba 55HX70 that exhibited the same convergence problems everyone else seems to have. I replaced the two STK392-110 ICs over the weekend. The procedure went well, but didn't fix my problem. I now have a slightly more consistant "dogbone" shape and I'm still getting multiple color images. I bought the service manual and set all the defaults, but can't access the convergence menu while in the "S" mode.
Also, in the customer menu, the 9-point convergence allows me to choose a color and allows me to choose one of the 9 positions, but does not display the crosshairs to adjust.
In the service mode, I can use the remote to toggle "RCUT" (1 button), "GCUT" (2 button)...etc, but when I reach the 7 button (which is supposed to be convergence adjustment) no grid appears on the screen. 9 button will bring up the self diagnostic display.
The Self Check display indicates-
BUS CONT: NG QH001
BLOCK: SUB (is red) (MAIN is green)
So...have I fried my new STKs and something else is causing the problem?
QH001 location in the manual is an IC, TC190C060AF-
Any help would be greatly appreciated.
