Question about Samsung SyncMaster 17 in. LCD Television

1 Answer

I am working on a Samsung SyncMaster 170MP. When plugged in the green on/off power button light flashes continuously and the screen never comes to life. I've tested the power brick and the outputs (14V @ 3.5A) are good, I also made sure that the PCs' video cable output is good and it works fine when plugged into another monitor. It used to come on after 20min or so but then it stopped doing that and continues flashing green power light. Is the inverter board or not? Anybody?

It sounds like it since you have the 14v going to the inverter. Repairing inverter boards even on lcd's is 50/50 shot, so let's give it a go. If you have a dvm check the ohms on the inverter xformers ( if more than one) they should be identical in resistance. Check or replace all electrolytic caps on the board. That's about all you can do outside of replacing it, Oh, see if you have a 5v source going to in inv. bd also, check that.

Does not turn on


Hello

With any monitor, check the following to determine if the issue is MONITOR related or COMPUTER related.

1. Verify the monitor is receiving power - use a known good power outlet and plug it into the monitor

2. Samsung monitors have a light on the power button - are you getting any color light from this? Orange means it is in "stand by" mode and is waiting for the PC to send it a signal. Green means the monitor is getting a signal from the PC and the monitor is on.

3. With the monitor on, press the buttons on the monitor to bring up the OSD (on screen display) that changes the monitor settings. If you have a green light on the power button and press one of these buttons (AUTO works best), this will display the monitor adjustment options on the screen.

If you see the on screen adjustments, your monitor is working and the issue may be with your PC. Move the monitor to another PC and verify the monitor is working correctly.

IF you don't see anything on the screen and the power light is green, the monitor has failed.

This could be the lights that illuminate the screen have failed (something that happened to my Samsung Syncmaster monitors after about 6 years of use) or the screen has stopped functioning. In either case, replacement parts are hard to find and a monitor swap is likely.

The display is in safe mode and you will need to reset the display to get the display out of the safe mode. There are 2 different model revisions. Please choose the method that will match your revision. Depending on the revision of the monitor, one of the following 2 methods should reset it to a normal state. This reset generally requires both hands and it is sometimes easier with another person.

If the serial number begins with an A and/or your power button on the far right (5th button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.
Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.


If the serial number begins with a B and/or your power button is in the middle (3rd button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see attached picture) and while continuing to hold the buttons, plug the power cable back in.4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

If you have tried the reset a few times and it does not solve your issue, please Ask a Question to submit a request through the system or call 1-866-752-6271 Option 1 to contact technical support.

Monitor not working


The inverter board has probably failed. Mine turned out to be the clamping diodes on the inverter. It would act like it was firing up but shut down just as the screen would normally come up. I replaced the diodes and it fired right up and has been working great since.
