| Anyone have experience or help troubleshooting this 6 years old -Freecycled- 17" Sony SDM-HS74 LCD ?
At first, when powered on, the symptons were: green power led on, raster with osd but only for 5 sec. or so, then shut off and led turns amber. Now, as you can see here, when powered on, this info is displayed: "Cable disconnected Input1: dvi-d" and the green power led stays continuous on. The board is LG 6871TPT285A model PWI7LS285A rev.A The caps are: Rubycon long life high ripple YXG c202 470uF 25V c203 470uF 25V c205 1000uF 16V c315 470uF 25V c333 470uF 25V tested power/inverter board conector pins with a dt9205b multimeter: 13.78V at +13V 4.95V at +5V could it be the microcontroller board ?
