#1 PS3 FAT CECHC04 Brak reakcji na guzki panela miga czerwona dioda

Witam
Posiadam PS3 FAT CECHC04. Wcześniej nie grzebana. Konsola po podłączeniu do prądu od razu zaczyna migać czerwoną diodą i miga w nieskończoność. Nie reaguje na przyciski panela ani na pada. Pomieniałem zasilacz jednak bez rezultatu. Nie wchodzi w tryb bezpieczny. Próbowałem reflow RSX i Cella jednak to nie zmieniło sytuacji.
Nie pojawia się ani żółta ani zielona nawet na sekundę więc nie podejrzewam ylod. Jest to moja pierwsza konsola więc przepraszam za laicyzm. Wizualnie nie widać fizycznych usterek.
Proszę o pomoc od czego zacząć poszukiwania usterki

Hello!

First specify the motherboard marking code.
If there is no reaction to pressing on the power button (no beep at all) this issue is definitely not related to RSX or Cell chips.

Disassemble the console and connect only 5-pin white cable of power supply to the motherboard (without button board and without two big pins of power supply connected).
Do you also get three beeps in this case, when you plug AC power cord?

Measure the listed voltages to ground. It is enough that only 5-pin cable from the PSU is connected.
- On pin 4 of IC6004.
- On pin 5 of IC6005, IC6006, IC6009.
- On pins 1, 4 of quartz X4002.

IC6004- 3,28V
IC6005- 3,29V
IC6006- 1,79v
IC6009-3,30V
On pin 4 X4002 is sinus aprox 32,76kHz 0,3V, pin 1 unstable fq 0,12v
