PHILIPS 19PFL3405H/12 - How to test Power board 715G3897 ???
Hello,
I'm testing this power board and I would like how to power on without TV to meter all voltages.
In this moment only have 5.2V from Stand-by.
I need how to jump pines to power on board and see other voltages.
Some Idea ???
TV Problem... no turns on, no standby led, only 5.2V from Standby......

Vestel 17mb25 + 17pw26-4
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....

VESTEL 17MB25-3 (red,blue green)
Hello,
I'm repairing a TV OKI V26A-_H with main Vestel 17MB25-3.
TV turns on ok but it had solaried image and I enter in service menu and reset to faltory values, and activate "Burn in mode".
Now, TV turns on but only shows red,blue,green cycle. I can't enter on service menu.
I was "googling" and I think If I change eeprom 24C32 (U103) I can solve it.
some idea???
thx.
