Sounds like warranty to me. Call them, demand to speak to a manager or supervisor, tell them what happened, and have them either walk you through it or send out a tech. They should also make available the earlier version of the firmware.
I bought my 4061 in November 07. Today after registering my TV online in my user logon screen I noticed a new firmware that samsung made available for download for 4061. I downloaded and installed the firmware according to the instruction and installation went OK.
But as soon as the TV restarted (as it was supposed after the firmware upgrade) all colors messed up and pic shows in negative. I called samsung and there is no help from them. They are telling that the firmware was created for 4061 TV manufactured before sept 07. Mine was later. There was no warning, no indication of anything that could lead me to think twice before doing any upgrade.
Basically they have created a trap for unscrupulous consumer and would refuse to fix. DO NOT DOWNLOAD any FIRMWARE UPGRADE TO SAVE YOURSELF $$ and trouble.
Now my questions are:
1. How do I downgrade the firmware to its original version?
2. Where can I can it and if downgrade is possible?
