Mitsubishi pincushion	Can't Post

I have a Mitsubishi VS-60VF1 rear projection TV with severe bows in both vertical and horizontal directions. I have the service manual, but am unable to locate the pincushion circuits or adjustments (not labeled as such). Any help in eliminating this problem will be greatly appreciated. Thanks, Ron

If you have a reasonable idea as to what you are doing and cant find any controls then there will be none. Check for the obvious diodes off the flyback and chokes etc then look for an IC, it will be a small one 6, 8 or 14 pin etc and see its got voltages and chokes or resistors feeding it are OK. If you type its number in google you usually can find out if you are correct. If all is well then it may be a corrupt eprom, for that you have to find out how to get in and reset. pin voltage is taken from the collector of the horizontal output via a diode or 2 and some chokes, start there
