I’m aware of the trick for fixing VB displays through careful soldering of the point where the weak adhesive normally holds the connection between ribbon cable and display PCB. I’m interested in doing this for two VBs I have with buggy displays, but I want to learn how to do it myself and am a total novice when it comes to soldering. I’ve done maybe two super-basic solder jobs before and they were dead simple, nothing precise or exacting like the VB fix would be.

Can anyone who has done it or does it often help point me in the right direction on how to learn the skills necessary to do this mod successfully? I’m willing to learn and practice soldering as well as to buy tools that may be necessary. Thanks!

I wouldn’t mind helping out, but if you have only basic experience, I am not really comfortable telling you to try it to be honest. If you still want to go through with it, I cannot give you much advice, other than the following. Be patient and never have the tip of your soldering iron touch the plastic or traces themselves!!
The best way of trying this, is getting some displays that are not repairable anyway and start fiddling out with that. I cannot really comment on anything else really at the moment though!

Good luck either way!!

Thank you for the reply. That was my plan actually, to get some units that cannot be salvaged and experiment on them. However, given my relatively weak soldering skills, I was also wondering if there were other activities related to fixing VB displays which would be good practice. I was also curious if any particular solder and/or tools are better than others for this kind of job.

Thank you for your support on my quest!

The most important is to have decent tools, that means at least a soldering station with temperature control. It is important to have the temperature set at a level that is not too low or high. How do you determine that? Tough to explain, you have to experiment a bit on that. Every station works a bit different that the other in relation to that. I know they shouldn’t, but that is life. The trick is to get the solder really flowing, but if you get it too high, you burn the flux away. Then you know you have set it too hot.
