TV HAS A RED WAVE ACROSS THE BOTTOM CAUSING DOUBLE VISION


If your TV looks 3D, warped, or distorted it likely has a convergenge problem. If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured. You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

There is a wave/bow in the bottom and top of the picture on the screen of my Toshiba 70HX50. When I am in the grid screen in the service mode, it looks like the center is 'bowed' out. How do I adjust this...


Slight error in the alignment of a projection TV is pretty much normal. If the problem cannot be seen on a normal TV picture, I would not spend the money.
However, if the problem is severe and causes colour double images, it is convergence and will need parts replaced - about $200-$600 depending on service call, parts, labour, etc.
Minor adjustment takes a skilled technician. attempting it yourself will likely cause the set to stop functioning. (Digital adjustment is not forgiving)

DOUBLE IMAGE ON SCREEN. tOP OF PICTURE LOOK LIKE A


That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

This is a convergence problem and is either bad connections at the convergence ICs or defective ICs. If you can solder, you can repair this yourself. Let me know if you wish to repair this and I can provide you with additional details.

Waves


If they are green, red and blue lines, you have a typical convergence problem that happens in almost every rear tube projection set ever made. There are two IC's that need replacing to correct your problem. If you do not know how to solder, unsolder, work on solid state electronics, you really should call out an experienced tech to assist you in this repair. These sets now a days have no user replaceable parts inside of them. A TV set as this one, should not be a place to experiment around inside of. Good Luck
