Re: Samsung 2493hm blue light blinking

ok well i will buy the right bulb then and also if you could link me a data sheet so i know what pin i would be more than happy to help but keep in mind that i do believe my main board has a short somewhere hopefully that wont effect what you need

Re: Samsung 2493hm blue light blinking

would a 12v 50 mA bulb due the trick?

if so with the 12v 50mA bulb connected it sat at 5.22v
if not i will buy one tomorrow




what would be the next step if there was a short on the main board

Re: Samsung 2493hm blue light blinking

i believe its the first due to the strange noise coming from the power board but what should be done next im kinda new to this

Re: Samsung 2493hm blue light blinking

no it drops down to something around 4 volts then i also hear a shock like sound come from the power board synced with the voltage drop

Re: Samsung 2493hm blue light blinking

ok so i tested what i think is the right pin


pic with arrow provided




and i got a steady 5.22v...

Re: Samsung 2493hm blue light blinking

hi im a half noob at this just trying to help friends that are full noobs at this stuff

OK i have looked at almost all of the posts on this monitor i got it for free so i would like to fix it because they would rock free 24 in hell ya
OK but here is what i think i know
the caps look good but i will replace them anyway but i don't know witch need replacing

i get a blue blinking light
measuring what i think were voltage regulators on the logic board i got odd results voltage on both leads on both regulators would reach 3 or 5 volts but synced with the blue light the voltage would drop so that leads me to think power supply going back to what...
