Question about Akai PT4298HD Rear Projection Television
Seems like you need to replace its convergence amplifier ICs (2 pcs). The convergence amplifiers are attached vertically to two heatsinks. When replacing these, remember to reapply thermal paste (white paste for better heat transfer from IC to heatsink). If you don't replace these, over time other components will be affected.
