Hi,
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.
