This document summarizes quality issues with LTX fusion parts from January to June 2005, finding failure rates of 7.7% for DOA parts and 12.5% for DUW parts. It analyzes the top faulty part numbers and trends showing decreasing MTBBF and increasing SMS digital faults over time. Concerns raised include the sensitivity of fusion systems to power cuts, quality issues leading to high DOA and DUW rates, and potential diagnostics differences between LTX and PSK systems.

8. FUSION in PHILIPS 8
• Fusion HF is more sensitive then other plate forms to power cut: In Q4’04
the faults found after power up was responded to Q1’05, and a great impact
on LTX, Jun 11th was same problem too. )
• 0185-01(PSCM) issue : Wrong action from LTX SG repair house.
• Bad parts quality & life time : They do take much prod time to verify parts.
(DOA+DUW 20% )
• Re-worked parts are with higher failure rates and more unstable.
• PECFH with re-worked are with higher temperature than others.
• Does LTX run diagnostics with same OS as PSK?
