CRT TV Bowing issue
I own a Sony Trinitron KV-EF29M31.
Recently, I had an RGB SCART port installed. The modder informed me that whenever I play a console through SCART, I would need to open the service menu and adjust the HSH (horizontal position) setting to center the picture.
Unfortunately, I accidentally changed a few other settings and, not having the original values noted down, I stupidly made the rash decision to initialize the TV, thinking it would restore factory defaults.
After doing so, the image became extremely distorted and bowed when playing games.. due to all the signal specific settings being wiped. The RGB SCART port is now currently not in use until the issue has been resolved. The consoles are all connected via Composite, S-Video and Component.
Fortunately, I managed to locate the service manual for my model and restored all settings to their STD values, but the bowing still persists.

Additionally my N64's (composite) picture will now not center properly no matter how much I adjust HSH, the image always shifts to the right, leaving a black bar on the left, even with HSH set to maximum (0F).
Please help!
