I would check the cables inside the unit. One of them could have come loose during the move.

How do I lighten a dark picture

Hi Richard,
Please try reducing the contrast a little and increasing the brightness till the dark shots are clear. Please also check the back light setting. It should not be too low.This should make all the dark scenes clearly visible if it only a setting problem. In case the overall brightness has reduced, please consult a local TV Tech.

I have a lg 32" tv and have connected everything

Dark picture means you have low brightness on the screen. Please increase the brightness. Also try increasing the back light intensity.

Dark picture, all color adjustments work ,but will not adjust bright enough. I changed the inverter board, but the problem still exist. Could it be the T-CON board?

Have you checked all the back lights. If not check it. Replace the faulty ones. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy.

What is the best picture settings for my smart viera e5 series?

What's the best flavor of ice cream?

The best picture settings depend on several factors, including personal preference and lighting conditions. Are you watching in a brightly lit room or in the dark? If there is light, is it coming from behind you or from one side? Or from above?

I have 20 inches tv there is a sound but no picture,it so dark picture

Since you say dark picture visible, then : Brightness control setting!

Check the resistors on the neck PCB. If you find the resistance value of these resistors high, replace them.

If No EHT is found then also there won't be a picture visibility.

1. Open the back cover and see whether you can observe a faint filament glow in the picture tube neck, close to the picture tube socket.
If there is no glow E H T circuit failure.

2. If the glow is observed check picture tube grid voltages grid no. 2. as said above.

( the points referred above are all for technical people)

No people inside the T.V but the sounds still there, i bought last August, this day only happen, i really need an answer

check the heater voltage (H) of Flyback to display tube (CRT) is available, or check the parts 'resistors' = (0.5 to 1 Ohm), through which the voltage. confirm whether burned or not connected. or the easiest is to see the back end of the CRT tube, whether such bright lights? when lit it indicates there is voltage to the heater.

When lit, you try to turn and raise the "Screen Adjustment" on the Flyback Transformer (FBT) near/under " FOCUS Adjustment ". your TV screen light will grow brighter as rotated to the right / upgraded. image will appear visible on the screen, but not too bright.

Backlighting issues on tv set (I think). Screen goes extremely dark after about 30 min. of viewing. Does not return to orginial brightness unless unit is left off for a long period of time

Lcd tv sets are lit by small glass florescent tubes called cold cathodes and, are powered by: ballasts called inverters... these go out just like your office florescent lighting the parts can be purchased online from electronic parts houses and, are easily replaced

Dark screen

if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.

If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.
