Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television
The most common problem with all 3 tube rear projectors is a damaged convergence circuit. The Samsung TVs are easier to repair than many others and the numbers that break down is not excessive. For every Samsung with a convergence problem there are a large number that did not breakdown. The fault is caused by bumps or noise in the AC power, not the TV design. This usually produces colored outlines around heads, etc.
Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.
This requires the replacement of the defective IC or ICs and any damaged or smoked resistors. 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.
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.
