HANNS-G turns off after 30 secs.

[jaseandwave]

Hi all,

I'm new here so go easy!

I have a Hanns-G HG281D display which was working fine untill recently. Now when I turn it on it comes on for a while, 30 secs or so then display turns off, the power light stays on though. If I power down then back up again the display comes on again for a short while the dies again.

Any Ideas? I've attached a few pics.

Thanks,

Jase.

Classic example of 'Two Seconds to Black'. The inverter controller is sensing a problem with the backlight system and is shutting down the inverter. Possible problems include bad caps in the power supply or on the inverter, a bad (aged or broken) CCFL, a problem with a transformer, a problem with the wiring to a CCFL, or a problem with the sense circuitry. It's even possible that it is caused by a blown fuse on the inverter.

The usual approach is to examine the caps on the inverter and the power supply for domed tops. If any are found, replace all caps of that brand. The usual next step is to substitute a known good CCFL for each CCFL in the monitor one at a time. Alternatively, check the resistance of the secondaries of each inverter transformer. Resistances should match within 3%. the transformers have 8 pins. The two pins at each end are the secondaries.
