There is a board on the right side of the tv called the convergence bd

There are little connectors that are on the left of the board
the last one is the power to the convergence Ic's

That is the one that is closest to you. they are little black conectors with wires in them


Carefully lift it up

Then plug the tv back in and see if it fires up

If it does do not run it long

just enogh to see the tubes light
then shut if off

If it goes on

your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you


If it does not go on then I would suspect the regulator in the power supply But
Most of the time it's the ics

Zenith Z42PX2D Plasma tv


Something short circuit with its circuit board. you must have through knowledge in electronics, and work experience to do repair work to this Plasma TV. As you know, plasma TVs are the latest technology devices, and a mere knowledge in electronics will not help. It will be best to get this set repaired by any experienced service technician or by the authorized service center for Zenith at your town. [Short circuit protection circuit energized, and latched the relay, not to supply voltage to damaged circuit board is the problem] The click sound you heard was the latch sound of the protection relay.

The tv works but without picture


YOU HAVE A INTERNAL TV PROBLEM ON A ELECTRICAL CIRCUIT BOARD. SOUND WILL COME THRU BUT NO PICTURE. IT WILL NEED TO BE SERVICED BY A TV REPAIRMAN. ON CERTAIN TVS IT MAY BE AS SIMPLE AS A CONNECTION CABLE FROM THE CIRCUIT BOARD TO THE TV SCREEN, BUT IT IS STILL A TV SERVICE REPAIR FIX. - SORRY

Westinghouse SK26H240S - Sound works but no picture?


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Convergence problem ,Help Please


Something is not right here. Is there any possibility that you can get the circuit designation (Rxxx) of the resistors that were "incorrect"? I am not aware of anything like this that can cause the "memory to be erased". The only memory in that area would be the factory convergence settings which can be modified from the service menu. Please try to supply the resistor IDs and I'll check on this.

Thanks,
Dan

Picture horizontal problems


There is a sevice menu but it is something a repair man has to adjust. Even to get to that menu is a matter of procedure. If the picture is not always squeezed down then adjustment is not the problem. If it is intermitant it could be a bad solder connection on the main board.Sometimes a bad vertical ic and leakey capacitors can be the problem..
Bottom line is there is not much you can do to correct the problem. You are going to need a service man

ProScan PS32500 32"-Picture has white static line & Static/burning smell


It sounds like the circuit board is arching over somewhere. It could be as simply as cleaning and digging out the carbon mark to stop the arching. This is most likely the screen or focus voltage causing this, if there are no parts that have broken down. This will damage the printed circuit board and make things worse the more you let this cook. This could be dangerous for you to mess with because of the high voltage present, so my best advise would be to get this into the repair shop as soon as possible before this board burns up. It should not cost all that much if the CRT board can be repaired. Good Luck

Tv picture blinks off and on


The on and off conditions is repairable and is not the tube,you should have it check out for loose conections and try not to use it or it will go bad for good and the repair will become expensive,Check power supply,horizontal driver transformer and crt board,If you are not familiar with tv service be safe and call for help.
