STK392-110 replaced on Hitachi

I have a hitachi 43UWX10B projection TV.. I was having a problem with the convergance on the Blue Gun. I kept getting an error number 4 after running the magic focus. After reading through the posts I replaced the 2 STK392-110s and checked over the board, but did not see what looked like any burn parts or bad solder spots.. Worked great for a couple days but then turned it on and the blue was off again, actually worse drooped way down on one side (left) and off a bit on the right.. After about 5 minutes it seemed to go away.. then comes back off and on. Thought about checking my solder points to see if one may have come loose although I had the gun hot and they all looked good when I was finished... I only paid about $5.00 for these semi-cond... Could they be poor quality?? I would think that if a resistor, diode or something else were bad the problem would be more constant.. HELP!!!
