    Yes, but it could be one or any number of capacitors in the convergence circuit that might not smell or look blown or show any leakage.

Hi, bad news, you have a bad hyper module which is NLA from Toshiba, you need to have a local tech change out all the leaky caps inside the module, a very tedious job that requires an expert at unsoldering smd devices, video-tek

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.

Toshiba Tv Problem


What is meant by "tears"?
If you can find a reputable tech he should be able to reflow solder a couple areas on the set and make your troubles go away.

When initially turned on the picture jumps around for several minutes


"Fonzie-ing it" ? It's terrible that I understood what that meant. lol

Sounds like the tuner has a bad solder joint. You may need a Repairman.

Wavy Screen on Startup


I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes. The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.
