First, please double check if the part/board no. (SSR-9010A-M2
) is the same as the original one. If yes, then other parts gone bad also aside from the power supply board. This is caused by faulty convergence chips (STK394-250
) on the deflection board (part no. SSR-2510A-M2
). Your unit used two convergence chips that is mounted on the large aluminum heat sink behind the flyback transformer.
I would advice you to replace both the convergence chip.
You need to prepare the following :
1. Necessary tools and test instrument2. Soldering Iron3. Desoldering pump4. soldering lead5. Thermal paste
.6. 2 pcs STK394-250Soldering TutorialHow to desolder parts on the board
Let the unit unplug from the outlet at least 1 hour to drain the voltages from the power supply board. Familiarize all connectors (take a picture of it if necessary to guide you replacing the connectors).
Please let me know if you need further assistance.
Hope I helped you.
Have a nice day!
