JVC AV-48WP30: CONVERGENCE PROBLEM!!! HELP!!!
U have convergence board issues. Sometimes over time the solder joints on the board go bad or develop minute breaks. U might try removing the board and resoldering every thing you can get it. U can also consider baking the board in an oven at around 270 degrees for about 8 minutes to melt all of the connections on the bottom of board.
Then remove, allow to cool, cross your fingers and see what happens.
Whats the part number for convergence chips on jvc av-48wp74
There are two of them that need to be replced as a set. They are both STK392-110 Convergence Ics you can get the original oem Ics from www.tvrepairworld.com
they are listed under the Integrated Circuit catagory you only need the one set. They also have the convergence repair kit listed for your model under the JVC repair kits the kit has both ICs all 12 resistors and the CD with step by step repair instructions.
How do you fix the convergence on a 2003 42 inch big screen tv?
In the menu on the tv setup you should find a test pattern that can be displayed for converging. In that menu there may be an auto converge which is much easier. If not, with the patter up you will have to manually converge the individual guns in the tv with the back off. There are adjustment knobs or screws for focusing the guns.
My 48 inch jvc tv has a green color to it what can
Okay so the green color that you see on the screen is because the coolant inside of the green picture tube is gone bad (it suppose to be cristal clear but now it is brownish and that makes the green color run all over the screen.) That just happens over time and I'm guessing the picture tubes have never been serviced. Now you got two choices
1- The easiest and fastest way would be to take it to a local repair shop and have them service the coolants of your picture tubes. I'm guessing it would run you about $165 or so to get them done (the three of them red,green and blue)
2-On the other hand you can do it yourself. It is not hard at all but it does require a lot of attention.
After the picture tubes have been serviced you'll notice the big difference.
You'll actually have a much brighter and sharper picture just like when it was new.
Let me know if you decide you want to do it yourself so i can post the instructions for you.
