Im working on this amp to try and get theese amps i have here back to thier owners before i stop the repair business for other people.
Anyway,
I replaced all of the outputs in this amp (irfz44's) and replaced the power supply fets.
When i power up the amp a blue light come ons for a few secs then a red led lights.
I have 1.49 volts on the output terminals. Any thoughts on where to check?

Outputs were blown and wrong outputs were in the amp. (irfz48n) I replaced them with irfz44's (orginals) I also replaced the HIP4082 IPZ Chip . But if they are anything like the HIP4080's i could have a defective one not sure
I'd suggest that you pull the outputs so that you can confirm that all of the power supply voltages are present on the various ICs.
Hi I have the same amp 1001dx when I try to power it up a blue light comes on for a few seconds then goes off also a power supply fet was blown ant advice
