Toshiba 35 inch picture tube problem

The picture on the screen is only about 6- 8 inches tall, not the entire picture tube size. Do you think the problem is the tube is going out or might it be related to a controller card? Thanks

How can i change my picture size on the toshiba tv model 36zp18q


To do this, you have to enter its service mode option. This display will be entirely different to that of user menu display, and have an other way to get into. If you wish to get more about how to enter service mode to Toshiba TVs visit this site. Pull up older posts there.

I have an old 36 inch widescreen Philips CRT TV which has been working fine for 7 years until yesterday when the whole screen just went blue with a series of white horizontal lines. The audio is still OK...


Hello
Since there is a blue screen atleast, I don't think that the picture tube is gone. The fault may be either to its chroma IC or video output section. In both sections fault cases, this type of horizontal lines [parellel to each other at about 1 inch or so apart the entire screen] will be seen. Just check the voltages at the three cathode, ie, red, blue and green of the piclture tube. This can be measured at the picrture tube neck card. If you have through knoledge in electronics, have patience and enough tools to do the work, inform me through Fixya. Without these, you can't work on a tv, especially in Philips.
Otherwise, get it checked by any expereinced service technician. OK.

I have a toshiba 32 inch 1997 tv. When I turn32G90 it


It sounds like the picture tube may be weak (because it's orange) but it going to half ascreen is not caused by the picture tube but likely a vertical circuit problem. If this problem happened suddenly (going orange) then the picture tube is probably good and at least worth bringing in for an estimate.

Wide black area top of the screen.


More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.

Good day.

The problem with your unit is that when your tube was replaced, it was not degaussed or demagnitized. The purpose of such is to distribute the color evenly unto the entire television matrix.
You can try to demagnetized it by rotating a magnet around the surface( but not so near) of the picture tube while it is operating.

Also, please check for the degaussing coil around the rear portion of the tube was returned and also check for loose contacts.

Standard CRT Toshiba TV - 4inch tall picture in middle of screen...


Hi,

 

Not familiar with your actual model.

But a comon problem with older Tosh sets is the 2.2uf electrolytic caps from memory they are usually red there is 1 next to frame Ic & the second is near Psu.

Allso check frame o/p IC for dry solder joints this is easy to test for.

Tap the tv while it is on if the the frame suddenly pop to full size picture you know its dry joints so resolder frame IC.

done tv needs professional help. the Electron gun internally is no longer capable of spanning the entire screen. Not likely anything can be done outside of professional help

It could be a bad solder connection on either the crt drive board that attaches to the neck of the picture tube, the video processing circuits on the main printed circuit board or the picture tube itself. If you can lightly bang the sides or top of the set to get the symptom to come/go, then it is most likely a bad connectiion. If, when the screen goes green, you see fine white lines diagnonally across the screen about a half inch apart, then it is likely the picture tube.
