Appliance:
Samsung PS43D450A2M 43" Plasma TV bought from Good Guys, Australia. About 3 years old.
Problem:
TV won't turn on
Symptoms:
When connected to power there is audible, multiple clicking sound. Once the clicking stops, the remote indicator led blinks periodically.
Investigation:
Solution:
Bought XSUS replacement board from ebay (search the "PBA NO"). From further reading here I found out that I can buy a later revision (better??). I bought it from user 'grr_price-attack' for $50 shipped from the UK to Melbourne, Australia.
Also the later revision is easier to get hence lower price.

Symptoms:

Investigation:
- There is a well known underrated capacitor issue (capacitor bulging) however upon inspection of the PSU, the capacitors were fine. There was no visible fluid, bulging, nor burn marks.
- Tried to disconnect XSUS board: Clicking stopped (TV still not on). So I suspected that the XSUS is broken. If the clicking had not stopped, then it could be the YSUS, or both.

Upon replacement, the TV works well :)
After replacement I upgraded the Firmware. Quite simple, just download the file from Samsung's website and put in USB stick.
