If this is an lcd tv, the toy has broken the LCD panel and would need to be replaced. The cost of the panel would exceed the value of the set. If you have homeowners insurance, you may want to contact them to see if it's covered. Sorry for the bad news.

Sony Trinitron screen turned pink


Hello
Absence of green is the problem. You see mixing of red and blue, which will look like pink.
the fault must be of its video output card. This card can be located at the neck of the picture tube. Check this card, for any loose solder. This is a common problem seen in most CRt based Sony TVs.
Just resolder all the suspected solder points on this board, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals.
images of two models of sony trinitorn TVs, [back cover opend] has been attached here. you can see the boar under suspection, along with the picture tube neck. [See the rectangulat printed circuit board attached to CRT base]3_9_2012_2_12_06_pm.jpg3_9_2012_2_12_38_pm.jpg

Set comes on with a blue screen with retrace lines,then shuts down. Turned down screen control on flyback, set stays on cannot control brill


The set is shutting down because the picture tube is been over driven, it is most likely the picture tube has a short in the blue gun, turning down the screen control drops the voltage to a safer level. The only other possibility is a short video driver and open feed resistor usually located on the video board on the back of the picture tube.

Rca tv screen gone red


If your able to take the back off and have experience in soldering then you can look on the CRT board on the picture tube for cold solder joints, it should be quite visible. There are 3 transistors that look identical so I would look those over closely. Those are your Red, Green and Blue Video outputs. If you choose not to and want to take it in to a service center try and find one with Free Est. Notice on your screen if you have diagonal lines, if you don't, that's a good sign. Let me know what you decide!

My tv was dropped and now the color is messed up how can i fix it


Unfortunately, this can't be fixed without replacing the picture tube. The drop caused a piece called the shadow mask inside the tube to warp or break loose. When that happens, the red, green and blue beams in the tube don't hit the right places on the screen. There isn't any way to repair this kind of damage.

If you had professional movers doing the job, their insurance should cover some or all of the cost of repairing the TV (replacing the tube, that is) or replacing the set. I wish I could give you better news.

Panasonic Color Rings


It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

Tv showing blue screen with flyback lines sound ok


Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket

Pink screen


Is your grey scale or Black and white programming pink?? Thats an indication that the green and blue grids on the picture tube are week or that the red is over driving. First thing is take off the back of the set. Find the end of the picture tube and look at the printed curcuit board there. see if you can find and red drive controls there. Put on a black and white pic and ever so slowly rock that red drive control a little at a time till the picture looks almost normal.. If you get it to be a little \less pink then stop right there but if it starts to get a bit green or blue then try rocking those controls all back and forth till you get the bese B&W picture you can BUT BE VERY CAREFULL as there is alot of voltage on this picture tube and if your not carefull it will bite ya. Now dont be too critical as the tube is a bit weak so you probably wont get a perfact grey scale so if after a while live with it or get a new set. Good Luck.
