Customer Question
Aloha Louie, we just...

Aloha Louie, we just purchased a LG 43 UJ6300 a few day ago. During the day the picture is so dark its difficult to see. We have gone on the Guide an tried to effect brightness but it doesn't seem to be taking effect. Selecting sport helped a little beut I'm sure there is another control/issue,

Technician's Assistant: Has this happened before? And have you tried unplugging your LG and leaving it off for a few hours?

It's brand new ( like 3 days and this happened from the start. I have "rebooted" the TV and cable box but not for a few hours

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

No it is only with cable TV when on an HDMI setting. the internal screen with a european lake like setting is normal brightness and contrast

Technician's Assistant: How long has this been an issue? What happened right before this popped up?

This happened from the first, I purchased the TV on the 8th Sept.

Technician's Assistant: Anything else you want the Expert to know before I connect you?

For a few reasons I don't have the capability of playing a CD to see if it is effected the same . I believe it is only TV on the cable. We have multiple TV's in the house all on the same cable and they are not effected. I'm convinced it is some setting on the TV that I am missing or applying incorrectly

I can get to the guide menu which has a setting that says "Picture" with several subheadings
TV Technician: Anthony_Infotech, Technician replied 11 months ago

Are you viewing via an antenna or a satellite or cable box?

Ask Your Own TV Question
Customer reply replied 11 months ago
Cable box
TV Technician: Anthony_Infotech, Technician replied 11 months ago

No the guide is generated by the box that is no good for diagnosis,you have to use the sets OWN remote control or press a menu or home button on the set itself, its the menu commonly used for adjusting brightness colour etc on the set itself

I am AT THAT SCREEN NOW. I am using the TV remote control. I went to home then to guide and am at a screen FROM THE TV NOT THE CABLE BOX that has "picture" in the upper left corner
TV Technician: Anthony_Infotech, Technician replied 11 months ago

So is the menu dark?yes you are now at therightmenu

Ask Your Own TV Question
Customer reply replied 11 months ago
Readable but darker than I would expect
TV Technician: Anthony_Infotech, Technician replied 11 months ago

Or is the menu nice and bright and unaffected?

TV Technician: Anthony_Infotech, Technician replied 11 months ago

How old is the set now please?

Ask Your Own TV Question
Customer reply replied 11 months ago
8 DAYS, it was purchased last week
TV Technician: Anthony_Infotech, Technician replied 11 months ago

You have a very serious problem if the menu is dark please though before I draw my conclusion try another input like a DVD player or similar?do you have anything like that?

Ask Your Own TV Question
Customer reply replied 11 months ago
I can't use a DVD right now because of how the set is wired. When selecting the source such as HDMI live TV etc, there is background scenerie that is totally normal. The menu is , as I said readable but not VERY bright
TV Technician: Anthony_Infotech, Technician replied 11 months ago

OK reboot the TV and the box by unplugging both from wallpower wait 5 mins then replug both back in again,let me know if there is any change please (give time for both to boot up)

Ask Your Own TV Question
Customer reply replied 11 months ago
I've done that multiple time with no effect
TV Technician: Anthony_Infotech, Technician replied 11 months ago

OK the catalyst here is the sets OWN menu being dark if that IS the case then you have a problem with that set ,the reason is because the menu is self generated and is sent directly to the panel (screen) via the t-con board so its either a t-con board panel issue OR there is a back-light problem, either way you MUST contact the retailer who will swap the set.

The DVD test would prove conclusively what I am saying however the sets own generated menu is good enough for this conclusion

TV Technician: Anthony_Infotech, Technician replied 11 months ago

I am sorry I dont have better news the only good thing for you is you just got the set and you have warranty etc , many people have issues like this and are not covered, it may also be a warning to get extended warranty

Just returned from the dealer. As I suspected he showed me a setting HDMI Vivid which fixed the problem
TV Technician: Anthony_Infotech, Technician replied 11 months ago

You said the menu was dark too?you see that statement is what was the diagnosis so the menu could not have been dark?if you had the dvd to check or similar that would have helped

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 11 months ago

As the menu is generated by the set itself it has nothing to do with hdmi
