hi to all, I have a Hitachi 46F500 and my converngence went bad for two months now.. i ordered the sonyo stk's from ebay and just got them home now with 6 resistors.. i try to take the board out now .. i managed to take out everything except for the Three main high woltage wires.. i am not sure how to remove those wires .. so i can take the board to a repair shop to avoid the home service ...if someone can lead me with instruction on how to take those off ..would appritiated verymuch. thnx again..
Have you read the following thread. There are several posts with instructions, etc.
The leads may be BNC connectors, which require you to push down a bit and turn CC about 1/4 turn.
Sorry I didn't get to answer your other post as I was away on holidays. To get out of static mode, you need to open the front panel of the TV and near the bottom left of the opening is a little blue button. Pressing this little blue button will take you into DCAM and out of Static mode. Do not hold the button down, just press it.

thanx for replying .. 57. i had a friend of mine electrisian and he changed the IC for me .. but when we turned on .. still the green color is in a bad shape and the blue and red too. I am very confused now .. don't know what to do ... dhe picture is little bit better then the one before though..i am trying to find that blue botton to get out of static mode but can't see it anywhere on the front of tv ..
1. Did your friend change all the appropriate resistors, use the appropriate ICs and check for cracked solder as indicated in the first link of post 2? If the appropriate resistors are not changed, the ICs can blow again right away, or the fix may not work.
2. The little blue button may be in a different place on your TV, however, I believe most people with Hitachis have found it on the chassis, somewhere near the left side of the opening from the front (not the back) of the TV. The button is only about 1/8-1/4" in size (it is really little)

i had a friend of mine electrisian and he changed the IC for me .. Big difference between pulling wires, installing them on switches and brakers compare to troubleshooting and repairing electronics! (IE: would you ask your family doctor to perform heart surgery on your self? or... Would you do it yourself in order to save a few bucks?) Today's electronics are integrated circuits and often involves surface mount that even a good technician might have problems repairing if he doesn't have the proper tools. Soldering ICs is not for everyone to do as pins are usually fairly close and easy to short when unappropriate tools or skills are used. If that TV is worth something to you, I would hurry up and consult a proffessional before it is too late... If you scrap your board, you might as well scrap the TV as the board is probably worth more than the complete TV.
