AGILENT HP 54852A 2 GHz 10 GS/s 4 CHANNEL OSCILLOSCOPE PARTS

Description

Up for sale is an AGILENT HP 54852A 2 GHz 10 GS/s 4 CHANNEL OSCILLOSCOPE FOR PARTS or REPAIR ONLY.
This scope has two problems:
1. Powers up, starts to boot Windows XP (but never finishes), runs for about 1.5 minutes, then powers off.If I enter the BIOS setup instead of booting Windows, the same power off will occur. When this happens +5SB (+5V stand-by for soft power on) goes away.
2. With a known-working power supply, CH2 fails calibration. Self test also fails. During calibration, scope will not detect the calibration signal on CH2. Because of this, it will not allow me to continue to CH3 and CH4. CH2 will not display any signal, nor will it allow you to position the trace off 0VDC center-point.
No returns accepted as this is for PARTS or REPAIR ONLY.
I have not attempted any repairs on the scope's acquisition board. There are no signs of damage, rework, or blown components.
The acquisition board has the following hybrids (many, if not all, used in 54853A, 54854A, and 54855A scopes.):
QTY 4 1NB7-8509
QTY 8 1NB7-8510
QTY 4 1NB7-8508
QTY 4 1NB7-8518
QTY 1 1NB7-8511
