Screen goes purple

The screen on my tv goes purple after a bit, and the picture is hardly watchable. when thetv is turned off, we have a purple flash in the middle of the screen which we did not have before. Does not do it all the time. Has started the last 2 or3 weeks. Thanks

you might have a couple of dry joints, and you might also have a bad PTC inside that degauses the screen when tv starts up. Please try another good tech for a service. Patrick

use your remote to go to your closed caption settings and shut off the 'text'.

Our picture has gone purple and turq

Try degaussing the TV. Unplug it from the wall and let it cool completely - at least one hour. Then plug it in and turn it on. (TheTV will only do this when it is cold.)

Universal remote PX-RC1 changed my PRIMA TV to something else?

sounds like you need a new remote. that circuit board is not too happy when it's crushed in like that. You might be able to make it work, but don't count on it.

How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

No picture

The main problem is from theTV menu.I would recommend you press,menu,then settings,then display settings,and last tv screen. After, you'll get options on how you want to make your screen look like.Example:wide screen, Automatic, etc.

Screen is too dark

with a flashlight at the back of the set often times there is an adjustment you can make WITHOUT having to open the set!!!

look for a little hole in the back of the plastic cabinet labeled SCREEN then with a flat screwdriver holding only the plastic handle, insert it into the hole and SLOWLY rotate until the screen brightens up until it is watchable.

This is compensating for age in the picture tube. you may get a few day or a few more years! of a much better picture.

If you start seeing some thin lines on the screen then back off you have gone too far. Do this adjustment with the brightness and contrast controls on the menu turned up all the way.

it is also safe to play with the focus adjustment right next to the screen if thing seem a little blurry. you will need two people one to watch from a distance for best picture.

Could be a weak Picture tube . You can try turning up the screen control but don't turn it up too much you'll get retrace lines in the picture . Turn it alittle at time until picture comes on then turn it down until the retrace lines go away . Then try turning the tv on and off to make sure it comes back on. Be careful you can get shocked if you do this while it is on and you touch one of the circuits . The control is on the flyback or the module thats on the picture tube it will say screen by it . If this does not work you could have vidoe problems or just the picture is no good . Good luck

Hello im having problems with my sony wega

It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer

Screen goes from blurry to clear to blurry

The first thing to check is for loose conections,the problem is related to the high voltage but it can start in the main board with one component loose,when the high voltage is developed it goes to what is call the distributor block,a lot of sets have the focus and screen controls coming out of this block for each picture tube,this block might be bad but before we go to him we need to check everything is solid in the main board.If you are familiar with electronics you can remove the back cover and tap the chassis with a wooden or rubber handle to see if the set reacts,if it does you need to be atentive what area makes it react and flip the board to do some resoldering,If you are not too familiar with tv service you need the assistance from a servicer.Let Us know how it goes or if you need more information.
