I'm trying to remove the I/V opamps in my Denon dvd 2900 but they are not co-operating.
The buffer opamps came off ok but the I/V pieces seem to be
krazy glued down or somthing!!!
I'm looking for some tips on how to remove these before I do some Damage!!!!
HELP!!!😱

Are you sure they're in a cradle, I seem to remember that those bigger Denons the opamps were soldered in?

They are soldered in....
I have used solder wick and lifted the pins. The others all seemed to have a tiny bit of glue or domething holding them to the board, however this one seems to have a lot more adheason and I'm afraid i might damage the board prying it off!!

Your changing them right? Time to send them to God.
Just cut all the legs and rip the opamp off then remove the legs one at a time, it sound like it may be a plate through board and you think it is desoldered.

I am changing the opamps to getter ones...
I'm sure it's not plate through and I have lifted all 8 legs.
The body is glued to the board and I can't seem to get anything under it to pry it up.
Is there a special tool to lift the opamps?
When i removed the other opamps on the same board I found signal traces under the body and I'm afraid ir I pry to hard I may pull the traces off the board!!!

Just swapped some smd opamps from my dvd player:
Bend a small L shaped hook on a needle (soft burned in a flame) Heat each pin of oa and lift pin up with the custom hook. When you lifted the 4 pins on 1 side lift whole opamp. Bend opamp few times and so break off the other 4 pins. Remove excess solder/pin remains with wick.

Try soaking a little fingernail polish (acetone) under the opamp, if they are "super-glued" down, this will disolve the glue.
