Hitachi 50UX22BA Signal Circuit Problem?
|
Can't Post
|
|
I have the Hitachi 50UX22BA, had it for years great tv. Recently convergence off, did usual magic focus, even manual adjust, to no avail. Read a post about hitting side to see if there is a loose connection. (Yeah I know stupid, anyway) It worked until few days ago, now powers up stays on for about minute then off. Red led on, all green led on (all go off same time). Once off nothing. I have service manual and have been trying to isolate problem. I get a service code of '43' Abnormal signal circuit (?) I haven't been able to find out any info on that? Any help? If I can trace exact issue can fix myself, just don't want to pull boards and replace unnecessary parts. Any help or resources or point the way!! Thanks
