Question about Televison & Video

LCD TV picture has suddenly gone bad - it seems like the rows of pixels are vibrating horizontally to make the picture fuzzy. This isn't a tuner issue as it happens on the on screen menus as well

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.

Model# kdl-40w4100 Serial # 8051767 2 years old Horizontal lines in 4.5 inch blocks at the top of the screen


I have the same tv model KDL-40W4100 and around the same age. At the moment I have 16 of
these horizontal lines over the entire screen and they seem to be grouped into 2 lines per row. They are also around 4 inches and two pixel rows high. I have been looking over the Internet for months and found nothing to troubleshooting this issues. In the last few weeks more and more of these groups of lines have been showing up and now i am up to 16 of them and it is becoming unwatchable. Any help from anyone would be greatly appreciated. I also attached a picture to describe it better. Thanks!

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.

Hello: Your problem seems to be in or around the tuner of the television, More then likely you have cold solder joints on the turner that needs to be resoldered. Also check the coax end protruding from the back of the set where u connect the cable and make sure it is not loose, a bad ground on this connector to the turner shield will cause this symptom. My professional diagnostic is that when the television is cold the solder connections are making contact with the board, and as heat builds up in the television while watching these connections tend to seperate and make limited contact, causing fuzzy picture and in most cases no picture just snow...

The set you have has a bad tuner assembly. At this point most likely you would be better off getting a new TV set. Good Luck

Bad Cable Input


Try using your RCA imput to see how the picture looks compared to the tuner picture,is possible your tuner imput is bad,make sure the conector is not loose,the overall picture should look different but not fuzzy all over,using a dvd picture thru the aux (rca)imput should show you the difference.If the conector is loose only it could be repaired but if it is solid the tuner might be bad and it will need to be replaced along with any board it might be mounted to.Let us know how it goes or if you need more information.

Video problem


You already have it diagnosed ,all you need to do is find the loose conection and it might not be just one,the set seems to be 5 years or older and it has developed other loose conections besides the one obvious one,if you are familiar with tv service you can look in the horizontal deflection area starting with the horizontal driver transistor and while you are correcting this one you will find other ones, some loose conections are hard to see even for the trained technician so if you are not too familiar with tv service be safe and get the assistance of a servicer,right now it should not be too expensive since you already know were to hit it.
