From: a218@aol.com (A218) Subject: Re: Datasheets for HA11244/NTE1544 Newsgroups: rec.games.video.arcade.collecting Date: 07 Oct 2002 12:30:49 GMT Organization: AOL http://www.aol.com My error - that IC is used in G07, NOT 4900 Key is to check the frequency of the waveform at pin 1 - vert drive out - should be 59.75 hz Also - the spread scan lines are often a sign of a cap problem in the collector B+ circuit - recheck C311 for proper polarity - then again if it were in wrong it would likely smoke and pop open. Might want to replace it if you have one handy - if not holler and I will mail you one no chg. Check and replace if original C301, 303, 306. Let me know if you need more help Art
