I'm lucky because I have bought a HP8753A with a good price, few years ago
But now,I have a problem with my network analyser. (error message )
When I start it, after its self test ( message OK ) , the screen freezes with this message " FATAL ERROR INTR", and the analyser reboots.
Sometime, the same default appears several time in few minutes. ( 3 or 4 times in 5 minutes)
And after that, I can work . . . . 30 minutes or one hour
And this message reappears again ( and it reboots )

Someone has detected the same default ? And what it the defective component ?
Just before this message appears, it seems have a light flash on the screen, but I 'm not sure

I have the technical manual, good knowledge in electronic and RF
If you have an idea to solve and save my HP8753A , tell me 
I uses it frequently . . . I I can't buy a new one

And sorry for my english . . .  I hope it's enough clear

Best regards
