SOURCE: Samsung HT-X40 System Problem

I've run across the same problem. For now I've run the optical cable directly from my cable box into my stereo and I'm good to go. I hope the update will be something I can download and use with my flashdrive since i'm not connected via a direct cable connection which I assume is how the update will be sent. I'm not sure if it will make it through my cable box.

This is very common in Samsung DLPs. The DMD board is going bad. You will need to replace it.

SOURCE: u600 screen blank

Hi,

Probably all due to a faulty flex cable that connects the screen to the main board.

I had simmilar problems so I replaced the cable and now the phone is fine.

How do I repair our Samsung LCD Television? I would really appreciate an answer ASAP. Where will my answer appear for my review.


Don't know what service provider you have, free to air, satellite, cable or what? Try feeding the TV another signal and see what it does. Play recorder movie from DVD, or if you have a VCR around even try that. If it plays the DVD etc, with no issues, then TV is not the problem, most likely the cable box, satellite box etc, could be as simple as a bad cable connection at the house, a splitter or street box. Eliminate all the simple things first, then look at the TV.

Check the LVDS cable !!! It is the cable that supplies the video signal from the main board to the LCD controller. If wiggling the cable clears up the problem or invokes the problem, you need a new LVDS cable!

If there is sound, no doubt, its signal input is OK. The problem must be to your Tv itself. If the LVDS cable, the cable that connects between the T'Con board and LCD panel have a loose contact, this type of faultcan occur. Re-seat this cable once, and check.

Blue picture


It is your "vergin media box" outputting a blue screen!
When this TV has no input it displays a msg box "No Input Signal" or "Signal out of Range" (PC video resolution is not correct.)

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.

Model 2780R intermittant Picture & Sound Failure


The set has loose power conections to the tuner and judging by the model it might have other loose conections in the chassis,the loose conections need to be resoldered and might not be easy to find,try taping the side of the set to see if it reacts while is doing the problem.Be safe and call a technician unless you are familiar with tv service.
