Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

Sir press the screen mode button in your remote below input select button, press the screen mode button repeatedly to select smart, 4:3, wide, zoom, or 14:9.

• Smart- Display conventional 4:3 broadcast with an imitation wide screen effect. The 4:3 picture is stretched to fill the screen.
• 4:3- Display conventional 4:3 broadcast non-wide screen TV in the correct proportions.
• Wide- Display wide screen 16:9 broadcast in the correct proportions.
• Zoom- Display cinemascopic letter box format broadcasts in the correct proportions.
• 14:9- Display 14:9 broadcasts in the correct proportions. As a result, black border areas are visible on the screen.

Hello.
On your TV remote control there is button "Picture mode" or similar name. You can change image to "zoom" or "wide" by using it. Sometimes if in "zoom" mode it still not fill whole screen - you have to change display settings in you notebook for external display.

it sounds like a bad t-con board. this board my not be sold without geting the whole screen. the t-con borad is at the top of the screen and connects to your main board

In the service mode there is a way to adjust the picture position. Can be done by Sony auth servicer.

go into your customers setting and change you aspect setting to either full or auto

Sony bravia

This blue is caused by magnetic fields. Either the speakers of tv is faulty or demagnatziser not working. Switch of tv and remove powercord from wallsockets. Leave for about 10 hours and plug in powercord and switch on. if demagnatiszr is working the blue will be gone. if not have youre tv demagnetized

If hometheatre or radio speakers are closer than ½ meter this could also generate coulouration of screen. move speakers further away. If tv is on and and being moved your static electricity can also cause this. So switch of if if you move your tv.

There is nothing wrong with you Sony Bravia TV and it suppport all HD and SD formats.

Are you viewing the HD version of the channel when it is showing a standard defination show. e.g SKY1 HD instead of SKY1.

This means that regular standard defination shows are in a 4:3 ratio and does not fill the whole screen. In order to view these type of shows you will need to tune to regular channel instead of the HD version.

You can check if a show is brocast in HD by going into the tv guide and checking for the HD symbol in the programme symposis.
