SOURCE: White line runs from bottom of screen to top

This is the rastor that you are seeing - it may be possible to adjust the contrast and brightness to remedy however if you have not enough range in your adjustments and it results in being unable to see a usuable image then you more that likely have a problem with the HT coil which must be repaired/replaced at the shop. This is likely to be "fairly" expensive! I take it this is a CRT TV - if it is an LCD then it would be interesting if the sympton occurs at 740 and 1080.

Faulty technika tv


A good way to test if a remote is working is to get a normal phone that has a camera on it.

put the camera option on the phone and point your remote at the camera phone. Press the button you believe to be faulty. whilest looking through the phone. if you see a little white light the button is working fine if not try a few of the other buttons to see if its the hole remote that is at fault.

the way this works is camera phone's dont like IR (infrared) so this will show as a little white light on your camera phone.

if it is the remote you could always buy a sky digibox remote. as the Default code will work your Technika tv. ie volume, channels, power, also the help button will change your source/av on your telly.

Hope this helps

Cheers

My original nintendo DS has little white lines in the top screen!


Well, if the lines stay on the screen even when the DS is turned off, it means the LCD screen is broken, thus the crystals are flowing and blotching. This means the screen must be repaired, however you don't have to buy a new one.

Nintendo has a page about original DS repairs Here. They also offer certain warranties, I'd see if one applies to your situation. (They also have a more broad repair page Here.)

If you feel like doing the repair yourself, it is apparently very easy and costs about $40 to replace the screen. There are many different repair tutorials online. (I just did a Google search for "DS top screen repairs") Here is one of those sites.

I hope this was of assistance.

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.

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.
