Samsung HPS5053

[dbier63]

This is a plasma set that originally powered on and had a nice picture. The only thing wrong was it had a thin red vertical line down the far right side of the screen. While troubleshooting I re-landed a ribbon back to the ZSUS while the set was powered on. Bad move! This caused an arc that blew 4 zener diodes on the lower part of the ZSUS board. I've replaced the zeners and now have nothing. Sounds like the set is on (minor buzzing on the SUS boards) but no picture or sound. Although the sound may just be a setting in the menu as I have pressed many buttons on the remote without be able to see the screen. So I am wondering if there is any other things I can check.
Thanks.

Re: Samsung HPS5053

Why do it while powered on ? I dont get why people do that its never a good idea even for testing. I repaired the same set with them diodes blown, I ended up polarising them wrong by accident , so check they are polarised properly. Also even still the red bar is a panel failure which is not actually fixable
