Hello,
I bought a SH Philips 55OLED804/12 TV with known defect in an attempt to repair it for personal use.
The symptoms when bought: Philips logo appears then tv turns off
Things tried so far:
1. Powering it on: Philips logo shows on the screen, sometimes with some minor artefacts then shuts down. Red status led flickers rapidly into two batches then repeats
2. Put it in recovery mode by pressing joystick down then plugging it to mains: The tv shows the logo then shows the android animation along with some minor artefacts on the screen then powers off. Red status led pulsates slowly
3. Tried to unplug the T-CON and check if led status changes with no luck. Red status led has the same behaviour
4. Tried Firmware on USB with no luck. The tv does not pick up the firmware
5. Tried NVM.eed file found on this community with no luck. The tv does not respond when with USB plugged in
6. Cleaned all connectors with isopropyl alcohol, checked for swollen caps
Next things i would have in mind to do:
1. Measure some voltages on the PSU but i did not find any schematics yet.
2. Locating and replacing the EMMC that store the firmware. Need to locate the dump files or trying to recover them from existing.
Do you guys have any other opinions or remarks? Thank you
