It will not fix your problem. The main board that you plug all your inputs is going bad. You can take it out and reflow it with a heat gun and it will last a little while sometimes. But you'll also have to leave your tv on.

Samsung LNT4065 started flashing 2 weeks ago...unplugged to reset 2hrs later back to normal...made a call to Samsung about this problem...contact with customer service sent email with firmware to download...


I'd say what you really needed in the first place is this:
http://www.ebay.com/itm/BN44-00167C-SAMSUNG-POWER-BOARD-REPAIR-KIT-/110735490949?pt=LH_DefaultDomain_0&hash=item19c8597f85

As to why it went dead...I think (and you should pray) that it's because the original problem just showed up again.

The original problem being the power board not functioning right and NOT what Samsung told you.

Chances are I am wrong, of course.

But I'd bet my lunch over anything any large company service rep reads you from a book.

Samsung LCD TV LN40A550P3F will not support 1080 format when hooked up to HDMI via Directv receiver.


Hi, is the directv box giving out 1080? There is an option on the box to select between 480, 720, 1080.
Also the tv has the same option.

Invalid format error with P1600 blu-ray and LG LCD TV 42"


It may be a firmware issue if hdmi works with other items such as playstation.
If no hdmi the main Pcb hdmi ports are bad and the main Pcb would have to be replaced.

Consumers cannot upgrade the firmware so a shop would be the only option.

You can do it your self, however, that is your total LCD display, it will probably cost in the neighborhood of $1300.00 for the display. They are not like the older projection tv screens that you could replace, these LCD's are the MAIN thing.
