Hi!

I am reparing a generic made by some chinese company marketed by indian company (HCL) 15" LCD model: HCM500. The problem with it is the display is very DIM, hardly display visible, does not have any problem with the cfl or inverter boards. the scaler ic used is TSUM16AL. according to the ic datasheet its LVDS output to the panel should be -ve voltages. but all voltages are in +ve. Can any one possibly let me know why this is hapenning. Has the scaler ic gone defective? is there any way to it.

Thanks

Jeetu

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.
