Unfortunately, I'm not able to assist with internal troubleshooting ideas such as boards and internal parts. I'm not sure what's causing the blue screen to appear. Is there anything that happens prior to it that you might be able to detail?
I bought my TV back in 2007, after a while I started getting that blue screen when using HDMI (blue ray and PS3). After contacting Samsung it was sent me a pen drive with file T-TULPAUS0-1032 which worked very well in the beginning however the issue came back again. Not so often for the PS3 but mainly for my blue ray player (BD-UP500).
What would be the final and definitive solution for this case?
(please don't tell me is to buy another TV ).
I even saw other foruns where it was mentioned maybe a board should be replaced...
I'm looking forward for your feedback.
