Question about Televison & Video

Display Issue, Hisense 42" LCD

I have a vertical white line (band), approx 4" from right side. Very easy to see when background is dark. When watching in HD or wide screen it is very noticable. Image in side that band is darker. In other aspects the band is outside the "box" and line (band) cannot be seen. Any Ideas? Cannot get Hisense Tech Support to return calls.

Hello
Do a factory default reset to this set. You can get details about how to do this, from its user manual. If it does not help you, the t'Con bard [Timing Control Board] may need replacement.
The board sill look like this.

SOURCE: I have a videocon 42

What you need is known as a "Z buffer" or "address buffer".

It is a board located UNDER the display.

Can't tell you the board number because you do not mention the TV model, but if you are up to replacing it yourself you better get to there anyway and see the model printed on the board itself.

There are usually two boards underneat in the 42'' models, sometimes three, but usually two.

You need to find the one located where the vertical line shows and replace it.

Replacement is not hard, but requires a bit more unscrewing because those boards are usually covered by metal shielding / heatsink, which usually has quite a few metal screws.

Other than that, though, it is not hard.

Why does my TV show discolored vertical bands and can I fix it at home?


The T-con board controls the picture elements on the screen. Usually replacing this board will solve the problem. If you can touch the screen and the lines disappear and later reappear, that says the screen itself is defective. The only fix is to replace the entire screen.

Vertical white wide band - Shivering fonts


Unfortunately that sound like a defective LCD panel. You can verify this by plugging the system into an external monitor. As long as the shimmering band does not appear on external display then it is the LCD. If it is under warranty I would suggest taking it into Apple.

CHECK IT IN THE DIFFERENT ASPECT MODES. IF THE IMAGE STAYS IN THE SAME PLACE REGARDLESS OF ASPECT. THEN YOU HAVE A LCD PANEL PROBLEM. PANEL WILL HAVE TO BE REPLACED.

You most likely have image burn in on the display if it is not in a straight line. If it is in a straight line than it can be dead pixels. It is most likely the first issue I saw this same issue at work with an HP plasma TV.

Dark vertical lines on tv screen


If under warranty then of course use that.
This is a display problem. One solution someone knowledgeable in electronics can try.
This problem can be caused by a bad connection fitting of the flat cables on LCD controller board. Dis-connect the flat cables from the LCD controller(T-CON) and carefully reconnect them. Try the unit before reassembling the back cover. You may have to disconnect/reconnect several times to show improvements if this is the problem.
