[QUOTE="pwatts, post: 606909, member: 146"] Great job! Those powerpads take a lot of heat to successfully remove. Another forum member had a similar problem with an ADV3002 on his Marantz processor though. Could be insufficient ESD protection perhaps to save costs and prevent signal integrity issues from the additional capacitance from the protection diodes. Alternatively perhaps insufficent power decoupling, or improper heatsinking via the heat slug. If they get very hot it may be worth using a stick-on heatsink, they're available from retailers like DigiKey. The Onkyo HDMI issues were due to shoddy soldering and the video chips consume a lot of current so I would imagine this is an unrelated issue. [/QUOTE]
