Ok try turning the tv of for 40 minutes by the power point and back on. that way it will reset picture - and should go back to normal please let me now how this goes ((By a rating

Make sure you un plugged it by the power point for the 40 minutes

also make sure there is no speakers or anything magnetic within 60cm's of the tv this can also cause the picture to have strange colors in the screen - if that happens simple Repeat the above......

HOW DO YOU SPLIT THE CABINET ON TOSHIBA TV CT-90159


Pop off front speaker grille, there are 1/4" hex screws holding the screen on, and a connector that needs to be disconnected first. The 1/4" hex screws in the back and sides along the mid section also need to be removed, then the entire top lifts off - be careful, the screen separates from the black plastic part (you might want to lift off the front screen first, that way you can be sure you have all the screws removed.) There was the black power section that was screwed in that needed to be wiggled off first, then the top just slides off easily. Easy to clean and reinstall by putting the black part on first, then sliding the screen up, over, then down onto the black plastic part. Replace all screws and reconnect the connector.

Lines on top of screen


Hi and welcome to FixYa,

Initially, sounds like a capacitor at the vertical section about to fail, leaking or blistered. Additionally, have seen some of these models suffers from vertical fault due to a defective capacitor in the power supply section or cold solder.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

ILO tv black screen on top black screen on bottom with only about a 4" picture screen in middle... can you help thanks jerry


Hello dacrewof6,

This sounds like your vertical section is malfunctioning. This can be caused by the vertical drive section which connects to the yoke transformers of your CRTs. I would suggest taking the set to a qualified repair shop and having them check the vertical section of the TV.

I hope this helps

Thank you,

My tv has this lines that bend over the front top of the screen and when an object moves through the lines the image appers from the the top of where the line begins...and the tv goes black every once and...


This sounds like a vertical deflection fault. There are some components that are failing in the vertical deflection area that are starting to fail. It is very common in many of the sets that there are electrolytic capacitors in the vertical amp section that are gong out of specifications.

When you have at the top or the bottom of the screen where the vertical axis is compressed, and the picture in the compressed area looks like it is inverted and going over on itself, this is called "vertical fold-over".

An experienced TV service technician should be able to service this for you.

JVC TV 27" Black line on top of screen


This is for the original problem.. Not the second post.

It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.

This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.
