Kenny, chassis # AA-2 ? If so, check L511, D502, 503, 504, C511, C513 and
check Q512 one of them or a combination of them are shorted, If you include
the chassis number you`ll get more responses as many models are covered
under
certain chassis numbers, Good Luck, Larry E

> Damon: I replaced IC301 - have pix and all functions. Now I have way
too much width. Called up service adjustment mode. Secured HSIZ (Horz
size); cannot adj. Can't see all the service writing. Missing the s on
service writing. Checked Q503 & Q504 in the pincushion circuit. They are
O.K. Also picture bowed in the middle even though I have a full pix. Any
suggestions? Thanks for your input. Kenny
