Eric H 12-28-2013, 01:40 AM Sounds like you've lost half your vertical sweep, or the linearity has gone way out of whack, possibly bad caps or a bad vertical IC, or both. I'm not familiar enough with the specifics of the set to offer more but someone will probably step up with some help. zeno 12-28-2013, 07:30 AM Dont remember the vert on those but we did sell a ton of them. Check for PC cons at vert IC very common on that vintage Sony. Most ran on +15 & -15 from the FBT be sure you have both. If not will usually be the diode & low value resistor +- 1 ohm. And as always electros but I would put them 3rd. 73 Zeno:smoke: |
