Question about Samsung HCM4216W 42" Rear Projection Television
These sets quite often lose their memory and can be adjusted with remote control , but , MORE often I have to change the convergence amplifiers. There are two amps with 3 channels each for the up/down left/right for each colour . You did not say if the blue was curved with this displacement , if so AMP or fusible resister . If resister open I will change the amps as a pair. You will need to clean the old heatsink grease off(it will be baked on) and apply a fresh thin coat .
Sorry not for the faint of heart or lack of soldering/desoldering
The remote control buttons change their functions when in convergence adjust mode . Let me know If you want the overlay and instructions to adjust.
