Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.
The repair for a Hitachi requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Some models don't have a separate convergence board and the board is not usually available for the ones that do have a separate convergence board. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.
If you change the original ICs with substitute "new and improved" parts that are talked about in the blogs, you will probably create problems. Use the original ICs and resistors.
Don't monkey with it.
This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.
If you live in Calgary, call me. If elsewhere, find a competent tech.
