Picture ''breaking up'' on Samsung LCD

I have a LNS-4096 LCD that is ''breaking up'' on all sources - it looks like the image is being blended up and distorted. This happens usually when the TV has been off for a while and will go away if I turn the TV on and off frequently but will usually come back. I took it into a local authorized Samsung service location ''TV is out of warranty'' and I was told it was the T-con board that needed to be replaced. I work at a high end AV dealer in dallas and have sold Samsung for years - I am quite familiar with component level service as well - so I have purchased the Samsung service manual for this TV. I can not seem to find a part number description of the ''T-Con'' board on the parts list however - Can you provide me the part number the service department needs? - Also, I did some research and found that the T-Con board may be a consistant issue on some of these panels and that a firmware update may fix - see:;posts#3020041
Is there a recent firmware I could get from you to see if this makes any improvement?

SOURCE: Sudden loss of picture and sound on 40

I do not think T-Con can shut down TV, all it can do to blank the screen, I mean stop picture data towards LCD panel.
Sony would not give T-Con separately as its counted part of LCD Panel but its available in some part shops.
Let me know model number of TV and what boards you have been replaced in TV.
Are these power supply and main boards.

Samung LN-T4061F - Dim Picture

Samsung LNS 325 1D-the screen is blue-no picture but perfect sound-what is wrong? Thanks

Hi m5720,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Thanks for using Fixya.

Samsung lcd 913v self test ok, no image when vga connected

This problem often occurs in samsung SyncMaster LCD monitors.

The solution is open your look for the LCD monitor power supply module (which have PCB connector to the AC power), on that board look for capacitors, now look for broken one which upper part is bloated, like the image below:
If you find a damaged capacitor as in the picture then you should replace it with the same value.

Is there any High Voltage DANGER when repairing a Samsung LCD TV

Just be careful around capacitors, which could possibly still hold a charge. Otherwise, there are warnings on parts that you shouldn't touch. I would say that the biggest thing to watch out for is getting stabbed by the sharp solder points. I always forget how much it can cut you.

Intermittently, picture seems to break up into

replace the cable from the source. if the images tiles up it could be the cable and I suggest doing this first: replace the cables, they are the lowest cost to check, and in some cases the cable company will replace the length of cable from the TV to the wall for free (or part of your monthly payment). You could always make your own the stuff for that can be found on sites like of course you could always buy the cable if needed. I am assuming this is occuring during normal TV viewing. if it occurs while watching DVDs or from other sources you likely have a problem with your TV and may need to get it repaired.

Picture quality problems (such as lines, fuzzy image, or wrong colors)

  1. Check the cables and connections: Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
  2. Check the  display issue with  a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal. For example: if the image quality issues occur while viewing TV , switch the source to a DVD player to see if the image quality problems go away. If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and . If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Try to Reset the TV ( LCD) quality options. Please look in to User Guide to make the TV to factory Defaults..
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV . If the image quality problems still exists across all types of signal sources, the TV should be serviced.

I hope that this should resolve the issue. However, if the issue still persists then please contact LCD manufacturer for further more on the issue.
