I am pretty sure u need to go to the menu and check your v chip or a button on the tv that starts with the letter v that will control the picture

Picture size does not work


Unplug the power cord for about an hour or more and provide supply to the tv .

At times the power supply can cause this problem .

If you have any substances generating EM waves in and around tv remove it .

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.

Toshiba 50H72 rear projection TV. NO Video


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...

The Hyper Module Is Defective / It Is Located Behind The Jack Panel On The Signal Board.
More specifically the 11 16v/10mf caps on that board need to be replaced... Not expensive, I do them for under $100.00 dollars..

Flashing picture when start up


What i would do id purchase a can of freeze from radio shack
wait till the picture is good then freeze one ic at a time till the problem shows up, once it shows up let it warm back up and refreeze to make sure you got the correct part.
found this on anther site:
My first guess is an electrolytic cap in the main power supply and/or a voltage regulator that feeds the deflection amplifiers.

The cost of repair is not much; the greatest challenge is finding the bad cap because there are so many of them and scattered through out the sections.

If you have a scope and can look at some waveforms and voltages around the deflection and power supply feeds you may be able to zero in on it right away
