Double imagery,with a yellow bow at the top and bottom,

Look at attached photos and tell me if they look anything like your problem.

Convergence problems are common, this set most likely uses two of the STK-392-150 CHIPS (attached photo of typical chips) and they are 2.5 inches wide and about 1.5 inches tall with 18 pins each. They are mounted to heat sinks with fins and a white heat sink grease is applied to the back of each chip (back is metal) to transfer heat quickly.

After 5-8 years the grease dries out and one of the chips overheats and fails.

This can be a do it yourself repair and if purchased on EBAY a pair of the chips will cost less than 15 dollars (I use a seller there).

Repair consists of getting at chips and replacing them--sometimes they will damage a resistor around them--easy to spot and the resistors are easy to test.

Under 25 dollars total parts cost.


I can assist anyone with this repair and have done hundreds of them myself---based on actual experience I know what to do here.

if the photos or this information told you something you did not know rate this solution as very helpful as I do this here for free.
