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.

Garmin 1340T boot loop issue. The unit


Hi,

Unfortunately, there isn't an easy solution for the Nuvi owner as it requires a custom piece of firmware to flash the unit to make it at least boot. This problem is often caused during a failed firmware and/or map update.

It sounds like a file was corrupted. Sometimes it is better to connect the unit up to a PC, delete the old map and then proceed to install the new one. There are so many issues with memory space causing failed downloads and corrupted files.

If the map file is missing, the unit will boot-up OK, it will just say "Map data unavailable" but if the map file or associated map files are corrupted, it can cause the unit to crash. Your PC won't recognize the Nuvi because you have the reach the main screen before the data communication mode routines are accessed.

We've had some success in restoring some of these units by flashing a "fix" firmware in "pre-boot mode" that doesn't try to load the map or map associated files. This should then allow the unit to boot. Once the unit boots, Windows will recognize it and then you can copy a map over to it from the PC. Reboot the unit and then flash it with the standard firmware.

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.

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.
