LCD Monitor Service Menu

08-31-2010, 08:51 AM

Hi!
I am reparing a 15" LCD monitor which is using a TSUM15AL-LF-1 MCU IC, the problem with the monitor is that "display is dim", contrast control dosent work, where as the Panel CCFL and inverter board is ok, have checked it with a good monitor.

This monitor is of indian brand "HCL", but made in china, OEM i guess.

Do anyone know how to display the service menu. And what can the problem with the monitor, i have googled for the service codes, no hope..

No datasheet of the TSUM ic, i heard its a topsecret ic.

Attaching a pic of the controller board.

Thanks.

Please help...
