Screen has gone grey and has fine horizontal lines on entire screen. Blue screen is out.

Either the screen voltage to picture tube is more than normal, or the video processor IC has damaged. There is an other possibility that there is no voltage at the video output card, plugged on to the neck of the picture tube. Anyway, your set need a through checkup, and the work is somewhat skilled one. Just check this site. Soemtimes you might get some details about this fault. The fault is called vertical retrace lines. Thin horizontal lines all across the screen with an inch apart. One among the posts published in the following site have details about this fault.
Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy.

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...

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.

Single green line spanning across the screen horizontally

I was just watching TV and all of a sudden the screen minimized down to a single green line spanning across the screen horizontally. The label in the back says it was made in 1996 so it is an old tv. Can anyone help?

Vertical line picture

problem is caused by the loss of horizontal deflection signal. It is quite surprising that the entire unit is still working, since usually, a loss of H-Out will disable the entire set. Problem can be as simple as loose solder connection to a more complicated defective horizontal circuit. I would suggest havint it checked by a professional TV tech.

Horizontal blue line

The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

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
