820-2530 ppbus .19 volts always stays green

[2informaticos]

Post resistance to ground (ohm scale) at 3V42 power rail.
You must get more than 30K...

 

[JohnB8812]

Yeah agreed less than 30Kohms this junk

I will test this later. Why are we checking for less than 30k on pp3v42 ? What does that indicate? I am guessing bad mcp, if so why?

 

[2informaticos]

Yes, lower value denotes bad MCP...

 

[shanenin]

Thanks 2informaticos for your patience and help

on a side note,any idea what would damage the MCP?

(I have not yet verified thst is the problem, but that uneven frequency seems bad)

 

[2informaticos]

Its age is a good reason to get bad...

 

[shanenin]

It is official, it is dead: 23k ohm.
