We did to but not for electronics. Saw a pic somewhere that reminded me of when we worked at the shop back east. Truck or piece of equipment having whatever issue, checked everything that applied to the issue but just for one or another reason, wouldn't let us see issue in shop. Customer had it happen and we are out again. Instead of hammer, I used bigger type of hammer, 357 does wonders. Funny is new part still had same issue. Someone back at shop fixed it someway. Was just one of many problems we had without a computer assisted engine. Even with computer assist it still might need a 357 or stick of dynamite.
