Hi !


I've a customer using the ADV7619 and they have runned in to some problems :


"We have had problems on our latest prototype building and suspect it may be the HDMI receiver that is the culprit . The problem we are facing is that the image " jumps " around , ie the lower part of the previous photo is displayed at the top of the next. We have also received yellow and blue areas on some cards , see the attached photos . Is this something you've seen before? What we suspect has happened is that our main supplier of prototype boards have run the cards by mounting the furnace one more time, this could affect the circuit ? How temperature sensitive are circuits for high temperature during installation ? When troubleshooting , we noticed that if we cool the unit with the cooling spray so that it is below 10 degrees the problem disappears almost completely.

How do we solve this problem."
