Dear nomoresonys !
Yes, I have 1 ohm value on RH1 when removed.
Thanks for your advice.
The UH1 (G1577) datasheet is incomplete. It's a low power operational amplifier.
I'm looking for the source of the two voltages, VAAM and HVAA.
The CM501 Shifter IC is OK.
My friendly greetings

This is my first participation and I apologize for the language as I am not very fluent in English.

Backlight + Sound (OK) but no picture (see pictures)

The measurements I made on the T-CON are as follows:

VGL=-7.98V / VGH=26.8V / VGHP=31.00V / VREF=17.00V / V12V=11.86V / VD33V=3.27V / V33V12=3.27V / VDD=3.27V /

S_PWRON=3.25V /...
