I tried to register my new Element Electonics 40" Model - ELDFT406. Says model # doesn't exist ? Also having trouble getting the tint setting.

First, I'm not an ELEMENT TV tech. But I do have a background in electronics.
* I checked youtube for "ELDFT406 tv" and there seems to be a lot of problems with this set. Looks like your LED back lite is not working. This can be repaired but as it come outside the USA and may not have a repair center in your area. I suggest returning it for refund or replacement. Though I would prefer a cash out and get another brand.

Two things to check. The T- Con board and the back light strips. The T-con board can cause dimming on parts of the screen. A bad section of back light LEDS can do it also.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Hi,
Just make sure with the play store settings, whether you have sign in with your G mail account or not. If no just sign in and try else register as a new user and try. If found still there were an error. Just try to restore the tablet. If you again found the same error then, shutdown the tablet and press power + volume up button up to 15 seconds, so that you will get restore option there and restore through that. Definitely it will work for you.

What source are on?

I have this same one and it shuts itself off at random, one time after only being on for 40 minutes. It started within 2 days of it being set up and it was maybe used for 6 hours total when it first shut off. The remote hardly works too. Other people have the same problems with this TV, read the reviews of it on Target\'s site. I got mine at Target so I have 90 days to return it and I\'m waiting until around the beginning of Feb. when HDTVs go on sale again. I suggest you just return it,. You can\'t even find it on the manufacturer\'s website.

Hi, unfortunately you're not the only one. I read some reviews on Target's site and many are having the same problem. I have one of these also and after only 2 days and hardly any use it shut off, that time was after it being on for 6 hours though. Recently, it shut off when it was only on for about 40 minutes. Don't bother with fixing it, just return it to where you got it. I'm waiting until HDTVs go on sale again, I have until around Feb. 23rd to return it. This TV also has remote issues where sometimes it just doesn't work. Return it and avoid this manufacturer!

If I remember correctly, this model has a switch on the motor which activates both legs
of the 220 to allow the heating element to come on. There is a wiring diagram under the
lid of the dryer and should show this. Hope this helps.

I think I have a solution involving far less effort. Have you tuned your picture settings? Out of the box, the settings are ok and the presets will do the trick for most. But if you're like myself, you want the best picture possible. Here are my settings:
