These sets use pico fuses ---a 2-2 code usually means one of the convergence chips is shorted and has taken one or both pico fuses out that protect the chips--set detects no voltage and shuts set down instantly--this model uses 2 STK-394-250 CHIPS---I can send you a photo of what the fuses look like--if you find either or both bad--you need to replace the chips--if you just replace the fuse(s) it will just do more damage.
They are not glass fuses--the set you have is a V22 chassis and the chips are location numbers: IC8C01 AND IC8CO2.
What is the location of the fuse. The board that has the fuse will have markings for location, ie f470 or something to that effect near the fuse usually it will also say what the value of the fuse that belongs there, 2 amp or 5 amp and also the voltage. If you have the set open look at the board underneath or on the top and it should note the fuse you need. Glass fuses are GMA fuses and solder in type fuses are called pico fuses
