Sanyp DS27590 goes dim after a second
Hi. Got a Sanyo DS27590 that goes dim after 1 second. Change channel,
perfect for 1 second. I don't have a print. Chassis is 27590-01. I ran into this before on a 35" Sanyo. 5 volt reg was a little high, IC681. Well, this one doesn't use same reg. All transistors check good, apparently, with meter. Same with diodes and zener diodes. 130 volt B+ is dead on so switch mode PS seems to be fine.Any input on the 5 volt reg for this DS27590 would be highly welcomed. Danny |

First make sure the closed captioning ALL modes are turned off.
Very common on a Sanyo if set to text mode closed captioning with no signal to get a dim picture right after channel change. David wrote in message ... Hi.

Disregard. I found it. Was IC681 bad. Something had gotten on the designator
number and I couldn't read it. Works like a champ now. Danny |
