Question about Televison & Video

Open Question

Samsung lcd tv, with line across screen, half way up, horizontal/one pixel high, appears black on blue screen, when menus are displayed- ghosts the exact layout of wording, pixel for pixel, exactly in line with menu screen, in same colour. pixels are brightly lit in that area only, but the residual black line is still visible across the whole screen.

On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

SOURCE: LCD TV picture has suddenly

The main processor board is starting to have unstability with clocking pulses. The normal fix is to change the processor board. What usualy goes bad on these boards are many of the electrolytic capacitors. These are all mostly surface mount types.

It would be very time consuming and expensive to troubleshoot to locate the bad caps and replace them rather than simply replace the board.

Sometimes there can be damage because the power supply or another board is at fault.

In the end, if your monitor is out of warranty you would be better of to replace it with a new one.

Black line (strip of pixels not working) horizontal across screen


If a whole line of pixels is dark, you've got a bad transistor in what's called a "Passive Matrix" display. For your future purchasing decisions, while an "Active Matrix" display costs a little more, it has individual transistors for each pixel, rather than one per row and column, so when a transistor goes bad, it only turns one pixel black rather than a whole row or column.

Can I see the difference


Visually, there is very little difference to the eye of the average consumer between 720p and 1080. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern.your tv is display format is 720p and blu ray is 1080p. what happen is it will be scaled into 720p. old tv set format is 480p 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another. 1080p, on the other hand, represents 1,080 horizontal lines displayed sequentially. This means all lines are displayed during the same pass. 1080p is the highest quality HD display format. 480p represents 720 pixels displayed across the screen horizontally and 480 pixels down the screen vertically. This arrangement yields 480 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.
