If the video is shaking, zig zag looking, etc your hypermodule has failed. This is common on your model. Some peeople call it hyper board, hyper module, etc..all the same.

You can get a repair kit for this from www.TvRepairKits.com

Power but no picture


the Y-SUS BOARD is for picture in tv.if the picture is not coming or not proper the Y-SUS board needs replacing .but if the picture is blurry or with linings reparing helps.but in your case the tv does not turns on with y-sus board connected only error led comes on.this means y-sus board needs replacement.
you can get it from www.partstore.com
---------
if you are not familiar with replacing the y-sus board its advisable to get it done by local tv repair technician familiar with your brand/model.
----------
This will help. Thanks please keep updated.please do rate the solution if helped.thank you for using fixya.

The red seems to be out of place on my toshiba 50h72 projection t


Replace both convergence ICs they are stk392-110 you will also need at least the six 1.8 ohm 1watt resistors. You can get replacement ICs and resistors at the following link and they provide free installation instructions so you can do the repair yourself.
heres the link.

Bad caps and solder connections, especially in around the 9v regulator just about center of the defection circuit... Not a terribly expensive job and certainly worth the repair if the cabinet is in good condition...
