Question about Projection Televisions

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.

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.

Our three year ol Samsung TV has dark horizontal lines across the top of bottom of the screen. It is getting worse


Welcome to fixYa!

When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.

The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.

If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.

now if you can replace them your welcome but i wont suggest that , cause you may break it more....!

any ways do comment if it helped you in any manner!

I have a Samsung DLP HLN 5065W and recently the TV started to get Horizontal Lines in it with a 2 inch black horizontal line across the TV and the bottom half you could see the picture and the top half...


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

I have a Mitsubishi WD-62525. In general the picture is great from all sources (cable, component, and hdmi). However, there occasionally are very thin, horizontal lines that flicker across the screen....


I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
