Vestel 17mb25 + 17pw26-4

[nashagui]

Bad image, good OSD.

I change EEPROM 24C32 and problem continues.

I tried with a external TDT, internal TDT and HDMI.

I look into service menu and check an error on HD.

I think that there are some circuit with a short circuit.

Looks like bad GAMMA Voltages on the T-CON board, it can be due to bad GAMMA Vref IC or wrong panel setting in the service menu.

Go into SM-4725 then find Lvds mode normally in the picture section and change its value. Problem solved. Also consider checking Tcon voltages could be gamma Ic as bud says.

I enter in service menu but i cant change lvds mode.

I think that problem is some lm1117 regulators.
