I am starting the repair on my SONY KP-61XBR38. I have taken out the D board with contains the STK4278-Ls. One has loose pins (23, 24) due to cold solder or heat/cool over 15 years.
Question: Someone has suggested ADDING small heatsink directly to the plastic top of the STKs using theremal adhesive? This is in addition to the aluminum tray acting as heatsink the IC is clamped to.
Does this seem like it COULD work or add any cooling dissipation value??
I really could use advice finding the resistors components to check. I purchased one Service MANUAL PDF from online CHEAPO site and was hosed -- it's missing almost all diagrams and schematics.
I guess I'll have to find a better, more expensive source for a complete manual.
