Hi, I have a Toshiba 57H81 projection tv. The picture looks like a sound wave from on a scope. It is 'jittery' right to left. If I use the POP and bring up the 2nd picture, it is crystal clear, even on the same channel. However the first picture remains 'jittery' and wavey. Any ideas?
I have the same prob need to change the resistors as a first resolution. there should be 5 of them, if you dont soon and i mean soon you could cause the skt to go bad and have to start over in your repair

This is the Hyper Module that needs repaired. There are several small sm caps that dry out in this model. It's the module standing up to the right covered by a can as we call it. I really don.t recommend you trying to repair it. One slip and that module is done and you can't by a new or rebuilt one anymore. Please let a repair center look at it and do the work. You won't regret it.
Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.
sounds like your green tube is set to high. take the front cover off and the plastic cover under that you will see a black box about 6x6 with 6 controls one is for focus the other is for intensity here a guide for sony but yours should be close.
This is a common fail for a Toshiba 57H81 the cause most likley is caused by the Hyper board, there are several capacitors that have weakened and need to be replaced, these are surface mounted and have VERY Fragile contact points, if your soldering skills are week you might want to take this somwhere to have it fixed
