Question about Zenith B25A10Z 25" TV

1 Answer

Turns itself off

Initially happened with an especially bright image.
became more frequent especially when cold.
the picture skews in from the sides (variable depending upon the brightness of the signal image) - then shuts off.
have had to watch snow for 10 mins to "warm it up", then could switch to a signaled channel.
now will not stay on.

What do you think?

    Power button no longer works. Many starts and stops of pushing the button before I might get it to turn on. IF I can get tv on, after a variable amount of time, the screen goes wonky and then shuts off. RC will not turn the TV on either

    sympton you describe. pulling in on sides and shutting down is caused by excessive crt drive,  find screen control 
     back apron ****** same or re adj r g b guns. could have circuit problem causing over driving of crt. if so would require tech services.

Mitsubishi TV 65 inch rear projection. WS 65809 I went thru the convergence ic chip replacement years ago. Love the TV. My problem now is that the brightness goes from full bright to full dim then...


The old Mitsubishi units had a super capacitor in the logic circuit instead of a backup battery. This capacitor became leaky over time, causing the problem you describe among others. Number one symptom is set has audio and dark or black picture when powered up. As the super cap charges to full voltage, picture comes and goes.

Screen does not show images


A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).
To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see the following for further info and a simple fix that may help:

Bright white light


I have had the same problem with my F-700

After calling Fujifilm Custom support here in Spain, I've noticed that camera series had a common failure at CCD SENSOR, NOT THE SCREEN.

IF THE PROBLEM IS CCD (IMAGE SENSOR) FUJIFILM WILL REPAIR IT FOR FREE!!!!

I AM NOT KIDDING. I'RECEIVED A MAIL FROM FUJI SPAIN ABOUT THAT

ALSO CHECKED THAT AT FUJIFILM USA THEY REPAIR IT FOR FREE

I guess the problem is CCD (at least in mine) because:

1- Started with
intermitent colour distorsions (dissapearing from time to time)
2- The problem became more frequent as time passed by
3- THE IMAGE IS PERFECT WHEN I PLAY PICTURES FROM THE MEMORY CARD

GOOD LUCK !

Too bright pictures


Try doing a test of the same image using different "modes" and compare the results - it may just be that you've got the wrong setting.

Blue color spread over the pictures


This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.

Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.

Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.

The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.

You will have to take the set in to have it serviced.

Samsung DLP HLR5668W has mostly dark picture + grinding noise


Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
