Hello everyone,
I have a problem with a Philips PC monitor model 273E3LHSB, the monitor at a certain point stopped working and did not show any signs of life.
I opened the monitor and checked the power supply and the voltages were all correct, on the motherboard instead I noticed that the 5.1 ohm 2 Watt resistor R710 was very hot (143 C) so I decided to replace the two voltage regulators of 3.3V (U701) and 1.8V (U703) and the monitor turned on again.
the problem is that the image on the panel is distorted and I can't understand what the problem is, and how I can identify it.
It may be that the Novatek NT68677UMFG control chip is damaged, but I don't know how to test it.
If someone could help me understand the problem it would be great, thanks in advance.
