Title: sharp image SI-325 25" med res color issue?
Post by: death69inc on December 03, 2009, 09:59:47 am
not sure if i have an issue or not

was dead except for a hum
OK I recapped the chassis after getting a 2nd cap kit 1st kit was stand res new kit med res that the chassis needed ordered the wrong one

either case

tube was in my van and it got pretty cold last night
pulled tube in house ... wasn't sure if should wait to try it but i fig I try it and if it did anything weird i turn it off

well it did sparks coming from the anode inside tube and its loud arking sound ... wasn't sure if this maybe caused by sweating of the tube cuasing it to ark wierd and should just let it thaw

or might be something else

now new issue is that its real dim

if i turn up the brightness on flyback or duaghter board it distorts the screen hourglass sort of effect

seems like it could be an issue with the flyback although you could have sustained some damage during the arcing
i am not sure,as i woulkd need to check the schems but i would trace the pincushion circuit
