Philips 273E3L monitor repair in Durban

[Johndaog]

Hi Everyone

I am just reaching out because my old faithful 27 inch monitor just turned off one day and wouldn't turn on again.

If I unplug it for 5 minutes and then plug it in.
It comes on but then switches off again after about minute and stays off until I unplug it again.

I've been reading about it and appears it might be power delivery to the panel.

I did overclock to 75hz using custom resolution utility so I was thinking that might have shortened the life.
I have since reset the settings to factory default but no change in behaviour

I hink the screen needs to be opened and perhaps a repair on the PCB or something.

Is there anyone in Durban that fixes screens with such issues?

Or must I save up and buy another one?

Then where can I recycle this screen?

Please help.

PS. I promise not to overclock again.

It is probably cracked solder joints, or a fauly diode

Open it and take out the power supply board (AFTER LETTING IT DISCHARGE FOR A BIT, THEN RUB AN ALUMINUIM FOIL BALL AROUND THE BACK TO DISCHARGE ANY CAPS), poke with a multimeter and see if any of the diodes or caps are shorting both sides

I highly doubt it's cause of the overclocking.
Screens get hot and hot+caps don't mix well.
If you feel comfortable with checking this, open it up and check for any caps with bulged tops.

I fixed many screens with this issue.

I'm no electronics expert but it sounds like a capacitor has gone bad. If so, it should be a simple and hopefully cheap fix. If you plan to dump it, let me know, I might just take it off your hands as a project.

This is a good brand - https://www.digikey.co.za/en/produc...MI4-3flYGmhAMVXAcGAB2fxQIlEAQYBCABEgKHw_D_BwE

You can also use a UV light to check for any caps that have leaked.
