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
**broken link removed**
is displayed 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
sorry, don't have a esr meter
tested power/inverter board conector pins with a dt9205b multimeter:
13.78V at +13V
4.95V at +5V
could it be the microcontroller board ?
