When I turned the tv off last night the picture was fine, but this morning when we turned it on this morning, the picture is very dark and mostly blue. 51F59A, purchased in Dec 2006.\r\n Thanks for any help

It could be your mainboard. How long did you have the TV?

Is it in picture in picture mode?

Sounds like a fault with inverter. What lamp have you replaced?

that is under warranty

is the screen dark?, if is it, see if the TRC filament is light, if is it afirmative, turn a little clockwise the fly back knob that say SCREEN and watch if there is a horizontal line at midle of the tv screen. if is it, your problem is in the vertical stage.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

try tapping tv on side with palm and see if it works it might be a bad video chip

your bulb has burnt out

how do i adjust the brightness if i dont have the controler?

Does the TV have a light sensor? If so, turn it off.
The light sensor limits the backlights intensity at night or when it's dark in your room in order for better vieweing convenience.

If you are in a dark environment, it really pains your eyes when the view is too bright. Same works the other way around. If it's day, and light in your room. The light sensor will dimm the backlight for it isn't needed.

Let me know if this solved your question.
