White line across screen

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.

Take it to a repair shop.

Lines down screen

We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Horizontal white lines across top of TV screen

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.

Poor picture quality

You need to consider the following tips herein as follow:

1) Field collapse (horizontal white line on screen)
R710 dry joints. Same as C2146TN & C2546TN problem solved with thanks to Mike G & Barty. Power off/unplug. Get to circuit board underside with aerial socket up-R710 is near top and right of centre-cluster of 4 joints best resoldered
2) Picture is horizontally narrowed and deformed
Capacitor C2913 (390nF, 250V) on the deflector PCB had lost capacity

Please let me know any update

Top of the screen Picture Problem

sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.
