That can be bad screen, T-CON board, main board, power supply.
Inspect the power supply first, then try reseating the ribbon cables between the T-CON and the LCD panel.

Sony bravia KDL-50W800B got only vertical lines when turn on.


You need to take it to a TV repair service, preferably one that specialises in Sony TV's. There is nothing you can do to fix this yourself.

Tip

TV shows either: black screen with: white vertical or, horizontal line


If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, find the too hot transistor or, chip; using component coolant; spray the too hot component with the component cooler until the screen comes back to normal. To fix: apply white coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.

Actually the model is cs-313050. its quite old. the problem is that the tv won't work in the way that when you turn it on (it won't even turn on anymore) there is nothing but a white or blue lineright in...


you didn't mentioned if it is a horizontal line but i think it is.
It seems that you have a faulty vertical I.C. that scan vertical line.Because you it is defective you've lost the vertical scanning thats why you have only a horizontal line on the screen.

You will confirm it by powering on the unit with your cable signal present.When the sound is present on every channel it is confirm that you have a problem on the vertical section. You must look for a qualified technician to solve the problem....

Tv goes to straight line in center of picture then


It happens when Vertical deflection stops as Vertical Out IC becomes hot or does not get vertical signal.
Please check electrolytic capacitors and dry solder joints in vertical out section in TV.

Lines on screen


Can you take a picture of the screen and post it? It is not possible for both the horizontal and vertical stages to fail at the same time to produce a cross. A picture of the screen would help significantly.
