HITACHI 53UDX10B Projection TV: Convergence Board

Regarding the removal of the Convergence board... How do you disconnect the "bridge-like" leads that connect this board with the circuit board to the left of it? Or do you not need those if they break? I am just concerned about those.

They just pop off ~ pull up and out on the right side of "bridge". Then just fold carefully up and our of the way so you can get at the board. You do not have to remove both sides of these. Very simple ~ just becareful not to twist so you're not bending and weaking the wires.

Hitachi projection tv 53uwx10ba - the Convergence ICs were replaced. When the PDKP bridge between convergence board and 2nd board is plugged in, it makes a noise. Kept that unplugged, the picture is...


Did set have this problem before you replaced the STKS?

I know these sets very well. If problem is different in any way from before you replaced chips.......double check all soldering or one of the new chips may be defective.

The more you tell me the better I can help.

Blue lines across screen with mirror images


Try adjusting the convergence. If it won't move see below

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Removing the JK07132-A convergence board


Unplug TV from ac outlet for few hours, this will discharge caps in circuit boards and you can take out desired board after unplugging connectors.
Always Be Careful while doing repair in TV.

More than likely it is a convergence problem. Best way to tell is to unplug the plugs marked red conv, blue conv, and green conv. Careful not to unplug yoke plugs by mistake, and make sure you mark plug and board when disconnecting. If convergence amps are the problem, set should power up with convergence plugs disconnected. Do not leave set playing very long. This is just to verify problem. Your welcome, Russmann.

Check to make sure you reconnected the jumpers to connect the board that you removed. Also, check to make sure no resistors are burning. If still no pix, make sure you reconnected multi pin plug by digital convergence unit (DCU). Next, disconnect conv. plugs marked red, green and blue. This should allow power to come up if chip(s) are bad. Next, check pico fuses on board by jumper connectors or in power supply. If these are open look for solder bridges around conv. amps. Also, if any of these are open check all zener diodes beneath heat sinks where you installed conv. amps. Probably 27 v glass zeners shorted if solder bridges were created when changing chips. Good luck, sometimes you just get a bad I.C,Russmann.
