Screen automatocally switches between zoom settings

Hi there, My Sony Wega just started exhibiting strange behaviour. I have always had the default screen zoom setting set to "Full" but could, of course, switch to one of the other zoom settings manually when desired. Now, when I turn the TV on, it begins switching between the zoom modes automatically (flipping randomly every few seconds). It will do this indefinitely until I manually set the screen to "Full" (or "zoom" or whatever). The point is, once I select a screen setting, it stays put. Weird..... Any help would be greatly appreciated.

My Trinitron's mostly fine, though it's a few years old, but it has a strange display issue. It's almost as though the picture is "zoomed in" about 8%, cutting off about 1 to 1 1/2 inches of...

This problems u are having it is not the causes by the tv,because ur tv it is a analoge CRT tv,don't have this functions zooming in or out or the problems just causes only 8% cutting off edges of the tv pictures only.If the problem it is happening to ur analoge tv it will have no vertical hold at all.The devices u are connected to the tv and using have zoomming in or out buttons or ajustment buttons of the sizes of the picture on the screen.Used the devices remotes controls to readjust ur zooming or pictures sizes adjutment.

My tv screen is zoomed in how to zoom out

  1. Check the TV to see if it has a ZOOM / WIDE option or control for adjusting the aspect ratio; if so, try setting it toNORMAL .
  2. NOTES:

    • If there is a SCREEN MODE button on the TV remote control, you can press this button until NORMAL is selected.
  3. If using a cable/satellite set-top box, DVD player or digital video recorder, check the device for aspect ratio controls and try selecting a different display option.

Please note that all HDTV channels project wide screen pictures. You can still go to settings and then picture mode and change the format to 4:3/full mode.

Missing Green colour on 36" Sony FD Trinitron WEGA

This is not a problem that a reset will fix. THe 5 blinks is a code that indicates a problem with the AKB circuit. There is a possibility that the picture tube is starting to fail, but that is rare. If you are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, let me know and I will provide additional details and instructions for a couple of repair options.

Sony Wega 32"TV - noise on startup

The slight flash on the screen is usually because the CRT (picture tube) is holding a better than average charge and this is what we call "pre-glow" The noise that you hear, is that everytime you turn it on or just after it has been off for a while? If only after the set has been sitting off for a while then your noise is the internal degauser for the CRT and that noise is 100% normal. The degausers in Sony TV's are so strong they usually make the plastic cabinet vibrate a bit.
