Is Worth Fixing Panasonic PT-50LC13-K Rear Projector TV


most likely a bad mainboard or bad caps in the power supply. Borderline on the repair-ability. I would check Shopjimmy.com to see if used parts are available. If they are it may be worth it.

I have a toshiba 46h84 the picture is very light and lines all across the screen what could this be?


Possible screen controls in the set are up too high---if you turn picture and brightness to zero does the screen get full black?

screens set too high would give diagonal faint trace lines in the picture.

These sets also should get a annual cleaning of the lens and sometimes the mirror inside= if this is the case the picture will usually look darker and dull ----this will not affect lines in picture.


the lens are easy to clean but other actions depend on what your response is to the above information.

Vertical lines across screen on my panasonic tv PT-61LCX65


Try setting a portable fan aimed toward the cooling vents on the back of the set. If this eliminates or reduces the occurance of the lines, this means a circuit that controls the off/on of individual pixels has developed a thermal problem. This circuit is ordinarily loacted on the main circuit board and is likely to degrade further. You might inquire at the Panasonic service center if they have an exchange program in place and they will probably be able to confirm my suspicions.

PT-47WX, Blue streaks across the screen?


It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.
