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.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

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.
