The plasma gases in the television have already decayed. Plasma televisions last about 60,000 hours with optimal usage (4 hours per day of use) while in real life people really have their televisions on between 6-12 hours a day that would be about 5-6 years of prime usage of their plasma tv before the television start to dim out or gasses begin to decay.

Hitachi 46F510 different channels are different brightness and to get them viewable I have to run the brightness so high that you can not see any text at all. Also all white areas are blasting white bright. Edges of the tv also seem darker. I am connected to a cable system.

Roger, if your contrast (sometimes called picture) and brightness controls are at max you can increase the tubes brightness by turning the "screen control" clockwise, be advised a little turn goes a long ways, don`t crank it too far or you will get retrace lines, you will have to remove the back from the set and follow the red wire down from the tube to the "flyback transformer" on the front of the flyback are 2 controls, focus and screen, do not move the focus control, this should fix your problem.

JVC AV 270305 Brightness not Bright enough.


Yes you could look for the capacitor that is leaky, probably in the 200v line, or you could just open back and turn up G2 screen control on the Flyback. You have Screen and Focus on this black transformer with a long anode lead going to the picture tube of set. Becareful, High Voltage!

Brightness of picture


If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

JVC AV-27530 Sudden changes in brightness


This sudden changes in brightness are caused by the change in voltage inside the tv,not in the outlet in the wall but inside the set,The changes are an indication something is going wrong and it needs to be corrected,the set does have a brightness limiter but it only works when the set wants to get brighter than normal,You need the assitance of a servicer to correct this problem.
