Hello,
I opened my first plasma tv. I already read the basic plasma troubleshooting guide and the simple plasma repair guide by samsung.
The TV does not start. No picture and no sound. The heartbeat led is blinking very slow.
What i did so far:
- I checked Vs and Va. Both are perfekt at startup and then decreasing. After that the TV just consumes about 10W
- Unplugging power from Y-sustain doesn´t change anything
- Unplugging the data cable from the Y-sustain changes something. The heartbeat led blinks faster and the TV consumes about 60W
- Ve isn´t coming up. It is about 10V
- I unplugged the Y-buffers like the way it was written here: https://www.badcaps.net/forum/showpo...42&postcount=4
- I checked the capacitors, diodes and transistors on the Y- and Z-sustain. I can´t find weird components
Does anybody know what makes sense to check next? I want to try a repair on component level.
Thanks
