dc250 touch screen

It suffers from bad connection of contact film around the touch panel .
So first thing take the touch panel element off the control panel screen.
All the bellow explanation is referring only for surrounding (frame) of touch screen where the X,Y contacts are (no need and is dangerous to apply heat anywhere else )

I used heater ( in my case Heater used for desoldering IC). Apply heat on the entire length (be carefull not to melt the film, how much that's a bit tricky) and use your fingers as your gluing it.
Mostly pay attention to corner joints you should heat them up and hold them with your fingers a bit more so it can make good contact and at last the contacts of the strip that goes to connector. Shame i didn't take picture. Next time first thing with a little tutorial.

Thanks mate,
Already got the same information. Now with your confirmation, i'm going to (try) fix it on that way.

Pictures would be great

Fast update made from pic from internet . Black lined are areas where should the heat be applied. Not anywhere else!!!!

Some need more some less to be heated never will now how much is enough .
It works 100% when you get in to it!
It is doing pretty well now 10 months on my personal machine.

I have bin a bit retired in last 2 years in servicing (it was my primary job before) . I always enjoy in this tricky things since old days
It was fun to see customers face back then when converting analog 5437 series touch panel from english to my native language.

cheers!

Great!!! I'm soooo very happy!! It worked!! I used a Hot-air blower (the one I use to soldering banners). Thanks for your advice, saves me money and time.
