Me: Thank you. I have a PN64D550 that is experiencing brighness fluctuations/pops. I was on 1018.1 and have been sent firmware to upgrade to 1019.5 which fixes the problem or is advertised to.
Me: Anyway, I did the upgrade and my understanding that in addition to the upgrade an OPTIMIZATION step occurs or is supposed to. The OPTIMIZATION actually corrects the issue.
Me: When I upgraded last night to 1019.5 - no OPTIMIZATION screen appeared and now the issue is still there.
Me: Can you show me how to force the optimization or do you need to send a service tech to the house to perform this?
Martin: Does this happen on all inputs (like DVD and cable box)?
Me: yes I am watching with HDMI from CABLE and from PS3.
Me: I somehow think something didn't toggle right and the optimizaiton step was fixed. On the AVSForum, everyone who is getting this firmware fix says that the firmware seems to have corrected the issue IF the OPTIMIZATION step occurs. Not everyone is gettting this though.
Me: I mean OPTIMIZATION step was skipped - not fixed.
Me: Someone else reported that 1018.1 upgraded to 1019.5 like me with same model did not work and Samsung is dispatching a tech to do something.
Martin: Just to confirm, have you got any USB from the Samsung with the firmware?
Me: yes i have the firmware file T-MST4AUSC 1019.5
Me: version info SWU_T-MST4AUSC_001019_I01_ES000_111202
Martin: Okay, I am checking the issue.
Me: Thank you.
Martin: I will be right with you.
Martin: Please hold on for a few more minutes, I am still working on the issue.
Me: No Problem.
Martin: Thank you.
Martin: I will file a service request so that current firmware will be sent to you.
Me: I thought 1019.5 WAS the current firmware.
Me: That's what the TV set now says on screen.
Martin: Please let me know your full name, contact number, email address, shipping address and serial number of the unit so that I can file the ticket.
Me: So what are you sending me if I have the current release?
Martin: Thank you for waiting. I'll be with you in just a moment.
Martin: We will send two USB drives, one for roll back to the previous version and one is for latest version.
Me: Which version will it roll back too? Can you explain please?
Martin: It will roll back to previous version.
Me: which version number? I was on 1018.1 before I did the update.
Martin: Yes, it will roll back to that.
Me: If you roll me back to 1018.1 and then reapply 1019.5 - that is no different than what I did already.
Martin: Now it will resolve the issue.
Me: Can you please explain to me how that will resolve the issue if I go back to the very release I was on?
Martin: I'm sorry for the delay. I'll be right with you.
Martin: Please wait for a while I am filing the request.
Martin: You will get it with in 7 to 14 business days.
Me: But, what about my question? I don't understand why rolling back to the version last night only to re-apply the same upgrade will fix the problem?
Martin: Generally this fix the issue.
Me: So doing this will cause the OPTIMIZATON step to kick in?
Me: So you are saying that your documentation is stating that this is the fix for the Optimization step to kick in?
Martin: Yes, you are correct.
Me: If this doesn't fix the problem can CHAT help me or should I just call a technician for warranty repair?
Martin: It should fix the issue.
Me: But if it doesn't?
Martin: then you contact technician for warranty repair.
Anyone ELSE have luck with rollback and upgrading??
