SOURCE: Black picture, perfect sound

hi...your convergence IC's have gone bad.
These IC's operate at a very high temp, and usually only last 4-5 years.
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 large IC's , probably STK392-040, or STK392-120's or something close...regardless - you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack.
Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go.
If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!
Hope that helps u alot...

thank u!!!

SOURCE: sound no picture

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

Theinverter is the high voltage board that provides variable power to thebacklight lamp. This is the most common. When inverter is faulty youcan get no picture, or a very dim picture that can only be seen bypointing a torch light with a 45 degree angle on the LCD surface fromvery near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
Thisis quite uncommon, but happens. If the TV had been hit or moved the LCDcable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
Thisis the board that controls the video signal, it is difficult to test,as there is need to read determined values on IC pins. To test thisboard you need to purchase a service manual and follow thetroubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where youconnect the video and audio cables, if a signal board is defective,then you may get no picture on particular inputs located on faultyboard.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

It all depends on where the set is located. Try looking in the manual. Samsung has them online for free.

SOURCE: Samsung ln-t4042h turns on, plenty of sound, backlight works,...

Check the fuses on the T-CON board and also verify that it does have 12vdc feeding it. If you look at your screen in darkened room you will probably see slight glow on the front of the screen.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

I have a samsung LN-T3732H television and my picture is solarized. How can I determine if the cause is from a bad T-con board or from the main board or from some other source?


The Tcon is the most likely cause of your problem so try replacing it first. You can get one from Shopjimmy.com or Ebay, just make sure the board numbers match. If the Tcon board doesn't fix it, then replace the main board.

My Samsung LN-S2651D has sound but no picture


Hello,

Check with Samsung, this model should still be under the 3 year warranty. You are having a problem with the backlight power supply. You can look on the back of the unit for the manuf. date, if its less than 3 years then go to www.samsung.com and process the online service request form.

I hope this helps,if so please rate our solution.

Turn on sound without picture


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

NO sound on HDMI3 port and when playing Blu-Ray DVD's the screen is pink


Go to the samsung website, and find out how to upgrade the firmware for your TV. You will probably need a portable usb memory stick to do so (if your TV is equipped with one). HDMI is an evolving technology, and firmware upgrades can resolve many of these quirky issues.

Here's a possibility from http://www.samsung.com/us/support/faqs/supportFaqList.do?group=&type=&subtype=&model_nm=LN-S4696D&dType=D&mType=UM&vType=R&prd_ia_cd=02010100&acc_ia_fl=&disp_nm=LN-S4696D
Which Samsung LCD TVs Have The HDMI 1.3 Interface? spacer.gif Of the LN-T series Samsung LCD TVs, those models whose last two digits are 61, 65, 66, 69, 71, or 81 (for example, LN-T4071F or LN-T466F) have the HDMI 1.3 interface.
Samsung LCD TVs with HDMI 1.3 interfaces also have HDMI-CEC (HDMI - Consumer Electronics Control). For information about CEC, click HERE.
For information about individual Samsung LCD TVs with HDMI 1.3 interfaces and HDMI-CEC, click HERE. When the Samsung LCD TV web page appears, select the TV model you want information about by clicking the drop down list under Product Finder on the left side of the page.
Though other series of Samsung LCD TVs (LN-R, LN-S, etc.) have HDMI connections, none have models with the HDMI 1.3 interface.
