Normallly, if the format button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made. For example: A Motorola Cable box needs to be set up to go to a wide screen when an analog signal is detected. It's difficult to determine the repair without knowing the hook up of the peripherals. Hope this helps.

I assume that since you do not have remote you cannot choose another AV channel on your TV. If so you can use the RF input using a RF converter to AUDIO /VIDEO or if not the sky input must be shared through a VCR/DVD or multimedia/DTS amplifier

On your remote control there should be a button that lets you change the screen mode, IE. Auto, Panorama, Cinema, Full, Normal, Zoom, etc...

Black vertical bars on left side of screen


when you are using DVD, there is no problem directly indicate the problem is in video game. You can try by changing colour system of the TV (PAL,NTSC etc..) or the video game to fix the problem.

you have to get into the tv to do the adjustment. take the cover off and then look for the CRT tube and follow the yoke cables that will lead you to the printed circuit. you should see some small tiny knobs there. something like vertical phase or horizantl need the verital to adjust the vertical size of the pic..good luck

This sounds like a microprocessor controller problem?? Try to reset the tv by unplugging overnight and starting fresh in the am. If it will go in av then your all set BVut if it dosent go into the menu to see if theres any kind of lockout in the set up for the av. If not then youll have to have the set looked at by a pro. Good Luck
