TV has normal standby and powers on, backlight flashes for a second then goes out. Can see video shining a flashlight on screen.
Get approx 5v to BLON then goes down.
Getting 24v to inverter VDD pins.
F101-105 test good.
T105 has a little residue by pin 1 where all others have a white dot.
Inverter board part # is AUO 19.26006.095
The specs for the 4005DXXXXXX(MS307T) transformers say:
The secondary resistance is about 0.8 K between S1 and S2 (or S3 and S4). The primary resistance is about 0.5 ohm between P1 and P2 (P3 and P4).
So I started checking with meter at 2k, not sure if I had the right pins for secondary but it's the only pins that gave me close to the specs:
T101 - .892 .888
T103- .896 .893
T105- .886 .886
T107- .889 .886
T109- .855 .885
T111- .879 .875
T113- .909 .909
T115- .873 .871
If I did that correct I see some deviations in T109 and T113.
Does it seem like an inverter board problem? I do not really have any way to test the lamps..
