The picture seems to be getting darker. Its not as bright and sharp as it used to be. Its about 9 years old but has not been used very much. Might it need a new bulb or something? 57HX81 Proj TV Color...

simple: remove back cover and locate the three large black lens you will see top and dead center, clean them with either a lens cloth or a paper towel with glass cleaner----they are the light source for your picture and should be cleaned once a year---as they get dusty the picture gets darker and duller looking.\\

Picture turns to shades of greens except the reds. doesn't happen all the time but more often lately.

it's a crt socket problem.try to clean the screen cable coming from the flyback and change the capacitor in the left side ot the fly back .you may also have an unsoldering resistor or capacitor around the flyback area.

The tv seems really dark.57in theatrewide hd toshiba

Go into the tv menu and select the Preferences menu and set your picutre preference from Theater to Normal. The TV is currently in Theater mode, wich is for viewing with no lights on in the room. Switching it to normal lightens the pictue a lot.

57H81 projection tv has very wiggly picture.

This is the Hyper Module that needs repaired. There are several small sm caps that dry out in this model. It's the module standing up to the right covered by a can as we call it. I really don.t recommend you trying to repair it. One slip and that module is done and you can't by a new or rebuilt one anymore. Please let a repair center look at it and do the work. You won't regret it.

Check all fuses in the power supply and look for any bad connrctions on the PCB. You are probably missing the 130 volt supply to the horizontal circuit. Common reasons are: Shorted horiz output transistor; flyback transformer, picture tube arcing , bad power regulator IC. In short, you need to get a qualified tech for this symptom. Hope this helps.

Toshiba 57H81 picture bounces. Can't tell if horiz. or vertical.

Unstable picture, wavy, jittery, and loss of sync are a symptom of bad capacitors in the hyper module. The problem is worse when the set is cold, but when warm the sympton gets less or goes away. In the latter stages the problem never gets better even after the set has been on for hours. There are about 6 surface mounted caps (10mf/16) inside the shielded Hyper module. The module is vertically mounted behind the jack panel and can be unplugged from its socket after unsoldering the 4 anchor tabs on the bottom side of the PCB. This type of repair should be made by a qualified technician do to the complexity of chassis removal and expert soldering skills.
