Hi,
I have KFC's 17" Smile monitor opened on my desk. It doesn't catch up to the Vsync (picture rolls verticaly). I have narrowed the search down to WT8042.
This thing ensures the positive polarity of the syncs (ie-reverses the polarity if neccesary) and signals the nature of the picture format (hor and vert freq. band, presumed resolution etc).
I have contacted Welltrend for the datasheet, but they say it's old chip and they have datasheet only in printed form, which they won't bother to search for and fax it to me...
So, I'm pleading for help. If anyone has this datasheet in scanned form (or at least the page with pinout), I would be very gratefull. Please send it to my email...
I can't wait to get the pissy neghbour and his monitor crap off my back. I don't understand what's so special about 17 inch CRT Smile, but since I have agreed to take a look at it, I would like to finish the job properly...
TIA,
Branko
