Have you got a proper one, could you check it, please?

U7400: 1: 3.34v / .380(1-red to gr) 2: .35v(1) and 8.39v (2), r7402 91kohm diode mode: .620(1) and .132(2) red to gr. 15/24: 5v / .380 40: 4.95v / Everything here looks good.

ALL_SYS_PWRGD 3.3V

Hello, Same as above, same info about communication error when restore too. The difference is that, when start installing system (step 4/4) current goes up slowly 0A to 1.1A and seems to be frozen (20,1V) on 60sec than goes down to 0A. Funny is that after take off a skw003 switch, current goes...

Btw, diode mode on plt_reset_l .400 (red to ground).

Hello, voltage on all coils (exl. L7550 & L7510). No V on plt_reset_l (power on sequence is incompleted?)

Yes,

Yes, I use swk003. Now, your suggestion about button play works, thanks. Next step of problem: I used revive (user data). „System can not be restored. AMRestoreErrorDomain 9. Failed to handle data request message (communication error, possibly usb disconnection)). (AMRestoreErrorDomain 0x9 (9))...

Hello there. Computer turned off while playing a game (roblox - for the full picture). No previous problems, water marks or other repairs. Perfect condition. The board on the table reaches 14.92V and .23A, the light turns green and then orange, the fan slowly spins up to medium higher speeds...

this is really strange to me: the supply voltage is negotiable up to 20V. This may indicate that cd3217 are working (all four). I know, the right pair has priority (encoded i2c address) but... I'm looking at soc_force_dfu --->>> 0V and .460 (diode mode /red to ground - not powered when test in...

I thought it was exactly the opposite ;) I will, thanks.

Hello, I’m sure but its funny;) Yesterday came a1990 and had similar fault (on first view of eye). I said: impossible, day by day the same? Finally, it’s been just a faulty usbmeter and cable ;) Have got brand new of both right now. Any way, I have got PPBUS 12.6v now and no short (that what I...

Hello there, its nice to be here :) 820-01700 in a2141. Board with a signs of previously repair (t2 rebelled or reflowed - ohhhh.). 20V on charger meter but amps increasing step by step from 0A to 2.5A in a minute. Ppbus 11.8V first than 20.3V and seems to be stable. In u7000 room, a "piggiess"...
