i lean towards loose connection or bad solder joint on the tv input

yeah, that was my first thought to,  but with the amount of times i plugged and unplugged cables into the thing i thought i my have seen the red flicker in or out.....i do remember giving the plug a bloody good wobble to see if there was a loose connection.

I managed to get ahold of a manual, this helped me get rid of the RGB display on the screen but there seems to be no way to solve the fact the TV starts back up on ch6 after being powered down whilst on the RGB input. Dunno know if i can get past the fact that i have to push the AV button   4   times to get it onto the RGB input,  it's really gonna drive me crazy.

Maybe i'll have to grab me a ArcadeVGA and test out the VGA to SCART on the 29" Grundig. You'd have to imagine the components in the grundig would be better than the panasonic??

usually the more expensive tv sets can be set in osd to start with the channel u prefer. others remember the last active one when the tv is switched off or in standby. my ( naomi ) grundig with vga in always starts with av4 ( vga ) when turned on . i havnt encountered any probs unless the input is 640x480 with 60 hertz , no matter its coming from a pc or a console like dc or xbox .

- get a service manual or google for service mode
- make sure your computer and cable are set to work properly

 - the vga plug on your tv can be damaged
 - vga in may have to be activated or set up in the osd to work as expected    
 - maybe the firmware of your tv doesnt support vga
 - maybe u need a special cable for the connection

some time ago i tried to enable a metz 100 hertz tv for vga input via scart . i figured out that a metzmade secret cable was needed and i had to flash a new firmware to suppport vga . that was a real horror . so i deciced the grundig with a plug n play vga modul would be a wiser choice.

i wouldnt say grundig is of better quality than panasonic . i all depends on the modell and fab year. lots of old grundigs of the 80-90 ties keep running for 20 years or more . but after 2003 its beko turkey stuff inside. on the other hand panasonic build some very good tubes . whats your grundig modell and cuc number ? i can tell if its worth the effort. btw soft 15 k will do fine . no need for a avga .

ps. usually the rgb or av displaying in the corner can be turned off in osd.

thanks for all the info...

I stopped the RGB displaying, thanks to the manual i found.

The TV has no option in the OSD menus to set the start-up channel.....bummer.

The Grundig is a  M 72-410/9 reference,  CUC 1842

Have you tried any 31.5khz games on the TV yet?  I'm kind of curious to know how they looked.  

Any Atomiswave or Naomi game like Hokuto No Ken or Guilty Gear should look incredible.
