When you have the back off, look for the flyback (high voltage) transformer. This is the part that has the thick red wire protruding from its top which attaches to the top of the picture tube with a suction cup. On the flyback there are 2 controls, the bottom one is screen and the top one is focus. Turn the bottom control (screen) down (counterclockwise) until the white lines go away and the brightness looks normal. Then turn the top control (focus) until the picture is nice and sharp. If the F connector has been pulled out and the TV has RCA (red, white, yellow) jacks, use those jacks and set the TV to INPUT.

RCA CRT TV thin white horizontal lines

Look for bad capacitors in the vertical deflection amp, and in the pin amp sections. This is common on most of these types of TV sets.

The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.

Wikipedia explanation about capacitor ESR:

White lines equally spaced 1" apart.

This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Toshiba colorstream 27A33 TV

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.
