Whats the model number of your set. as different models have different meanings for a 3 flash error code. Please respond to this same post.

    Thats the error code for the convergence ICs. Your model uses two STK392-110 Convergence ICs. Replace both of them. You can get replacment ICs with free instalation instructions with pictures at the following link.

    You wont need to remove the high voltage wire as the Ics are located on the signal board which is on the far left looking in the back of the set. The resistors are six 2.2 ohm 2watt resistors R7048, 7049, 7050, 7053. 7056 and R7059 all 2.2 ohm 2 watts.

    Careful if you see ICs less than 15.00 as they are not worth getting. The site I posted have origional Ics and I use theirs in all my repair jobs.

    They stay attached to the board on the left and seperate from the board on the right like a hinge just pop them loose on the right side.

My Panasonic 47 inch rear view projector is hdtv ready, what do I need to buy to recieve pictures in HD


You should be able to receive the HD signal from your cable company. If you are still receiving your signal over the air, then you can buy an HD tuner. I found mine at Best Buy for $179 a few years ago. It will come with component outputs which is the HD signal.

I'm using my 70's vintage antenna on my house to receive the 3 local channels in HD.

Good Luck,

Samsung HC-P4752W Blurry ONLY on HD Channels


Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
