Question about Toshiba CZ36T31 36" TV

2 Answers

Bottom and top part of screen black

Only the middle part of the screen is viewable, if you let the T.V. warm up hitting it on the side clears the problem up.

I will purchase a new unit when my money situations improves..

    But commonly vertical IC is in a single line package. See the board marking usually sections are labeled. Look for vertical section then look for an IC within the mark section.

This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up


Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

Big black square in middle of screen picture top to bottom about 36 " wide good audio and picture 6" on right and left side displaying.


If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

52" Samsung that the top half of screen goes black.


the HDTV has a heat-related problem check your fans. Do they remove heat? the vertical chips paint the screen from top to middle and, middle to bottom so; your top to middle vertical chip is overheating as is your video chip; that is why you have "glitter" in the back ground. get rid of the heat or, bye,bye TV.
