The black screen problem of your TV can be attributed to a backlight driver failure, busted backlight, or LCD driver failure.

The flickering indicates a failing backlight driver or a failing backlight. The screen should be totally black, without any glow, when either of them is not working. To verify, grab a torch and shine it on the screen. You will be able to see a faint display telling you that the backlight is busted or the backlight driver is faulty. If not, the LCD driver or the LCD panel itself is faulty, although it has a low probability due to the symptoms of the problem. The only way to fix the problem is replacement of the faulty part. You may need the service of a qualified technician to determine exactly which one is the root of the problem that needs replacement.

SOURCE: I have coloured vertical lines on my 40-inch

is the screen full of vertical lines? It sounds like your Tcon has gone faulty but...there is hope. Firstly, only if you are competent with electrics follow the procedure bleow, else get a qualified tv engineer to inspect your tv.
Remove the back cover on the tv.Looking in from behind, check the power supply which is the board connected to the mains power lead. Check the capacitors, making sure none of them have bulging tops.These are the components shown below.

The caps shown below are an example of faulty caps, with their tops bulging.

This model of tv is prone to this condition, and if you have any bulging topped caps, replace them.
Next check the Tcon LVDS lead connection. The Tcon is the board located top centre of the screen and is enclosed in a metal plate.It has a lead connected to it that goes to the main board. Clean the connector at the Tcon.Be very careful though because the connection is fragile. It can be removed by gently squeezing in either end of the connector and gently pulling outwards.If these procedures are not successful, replace the Tcon.

Bush 40 inch tv sound but no picture 2 yrs old, any help?


For a Bush, not bad to last two years. Maybe more economical to replace it rather than a repair. Possible backlight or power supply fault.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

My TV has a green / purple tint on the corners. Help?


It might be due to picture tube problem... As its too old, the picture tube might be weak and hence you might get colors at the edges.. Better replace the picture tube with a new one to solve this problem

Have NEC LCD 40 inch tv which now has no sound or picture with coloured lines down he screen, is it fixable or has screen given up??


Hi,

Uh-Oh....Vertical lines, NO PICTURE. That is NOT good.

Did your TV get hit or fall over?

The LCD panel is actually broken.

If you had a picture on it, it would still be a bad LCD panel, but when you get lines and no picture, it means the row/column bus has been severed somewhere.

The downside is the LCD panel will cost the same or more than the TV set.

I wish i could have a better solution.

Let em know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
