Tv stays black

Do you have audio and if so can you change channels to hear other programs? If so have a bad vertical IC. Have a tech turn up the screen control to see a white horizontal line. By your question I would say this will correct the problem.

Split screen, kind of inverted w/white wavy lines

It is a calibration problem, let me see if I can find some schematics for your tv.

Pictures goes to distorded wavy lines.

This could be attributed to tuning reception of your tv. If your using antenna only, it is most probable. If cable, check your line.

If this is a crt type, moving that tv with that size could somehow bend its circuit board. Loose connection is a probability. Could be some minor component is detached from solder. This can be attributed to tuner and vertical IC.

Just for an input.

Have a Sanyo TV with the white line, screen black problem. Also have a similar Sanyo TV. Would like to switch out the parts from working TV to the non-working TV. Any idea of what this looks like or a link...

repair that one with a line a cross a screen.
firstly open both tvs
on your far right, there is a transformer with a cable going to a tube, near that is small IC, for verticle amplification, change that one togather with one electrolictic capacitors,connected to a IC and a and a cable going to a scan coil.
that is the only problem on tv with a line

Wavy Lines

some type of electrical feedback try upgrading your cables or tightening the ones you have. what might work best is a line conditioner i filters out any feedback you may be getting and cleans your power supply they cost from 50.00 and up best buy or circiut city both carry them or online as well
