Re: picture keeps shuting off and seems to be missing...

Power supply problem, why was the(guns) or CRT'S replaced did they leak flude from them? if they did the deflection cba is damaged, and can be replaced and should have been at the time.

P.S. if this is the case you should call philips direct, and git them to replaced the TV.

Picture starts out clear then slowly fades out to a totally blue screen. Audio stays fine.

Have gone from a good picture to green and blue picture.what happened?

If you are connecting the unit by componet cables (RED,GREEN<BLUE) check the cables first to make sure all are connected. If you find they are ok then your red tube may not be lighting up. If you are using a cable box try connectioning the set direct to the cable outlet on your wall. You could also be missing red drive signal to the CRT, in which case service is needed.

I have a 10 year old Hitachi 53FDX01B TV. It was working fine until last night when I noticed that the picture contrast was very dark. I tried to adjust the picture using the TV's on-screen menu to no...

I'm not an expert in rear projection TV's but i know that the 3 CRT tubes have a verry high brilliance output so i would check the power of the brillance circuitry, could it be a defective OVER HEAT SENSOR that monitors the tubes keeping the voltage down ? becaus i know that they ave a verry sophisticated cooling system (some even uses cooling liquid)

Hope it helps!

My picture is getting darker and I can't brighten it up enough . would all the lamps be going out or what ever power them up be going bad.Any voltage checks be performed??

this set is over 11 years old now. All RPTVs have three CRTs light guns that create's massive static electricity. if this sets lenses and mirror have never been cleaned, this is why its getting darker. there is probably a massive build up of dust/dirt and grime on the light guns and mirror. clean these and it will perform like new again.

check the high voltage with the screen control turned up high where there is no raster. suspect problem within the video circuit where there is no high voltage or defective picture tube.some time when the screen is black and the screen control advanced,you can see if the tv has video or vertical or horizontal problems on the screen.service the high voltage circuit if there is no raster or high voltage is raster can be caused by the no heater or filament in the CRT.---- a defective picture tube can cause many problems, such as, poor brightness ,missing colors,intermittent picture,poor focus,a single-colored raster,arching in the gun assembly,retrace lines in the picture,negative picture,chassis shutdown,noheater or filament lit and no raster to name a open filament or heater can cause no picture or no raster symptom.a defective CRT can have an extremely bright screen.loose particles of the cathode element can lodge between the grids and cause an intermittent black and white picture. simply tap the ends of the CRT gun assembly and notice if the picture begins to flash off and on.---- with a leaky picture tube after turn on the raster dims and get extremely bright.a dim picture with no green in the raster can result from a bad green assembly. a heater-to-cathode short can cause a raster to change colour or a result in no raster at all.replace the picture tube if there is severe arching in the neck of CRT. excessive brightness with retrace lines and a vertical collapse to a thin line can be caused by a bad coil on the neck board of the picture tube.rejuvenate the picture tube when there is very bright green screen. check for the resistance change on the resistors of the CRT neck board for an excessively bright picture with retrace lines.excessive dust inside the CRT spark gaps within the picture tube socket can cause the very bright raster and the chassis shutdown.a defective video amp,luminance buffer,or reference transistor can cause a bright picture with retrace lines. -------- for getting any required parts to replace you can get it from or from or from --------- thanks.please do rate the solution.thank you for using fixya.keep updated.

My tv keeps shuting off it makes a buzing noise. I have a hitachi. When I turn the tv off in a minute it will turn off.

It seems you might have an issue with your color wheel, when they start going out you get that sound, and it can gbet to be very annoying.
