I have a Hitachi Ultravision TV Model #50ux53k v7h002332. The remote is working and also changed the Batteries. The Tv is not reacting to the remote like it should. It randomly will not turn on or off and...


if you have to hold the remote very close it is likely a bad remote receiver in the front control panel; the only other reason would be a dirty lens there or at the top of the remote.

Let me know if all manual front buttons work normal.

Good Day, egipson;
When the CRT's Coolant (fluid) get onto PCB's, one can clean the boards with acetone. BUT YOU MUST MAKE SURE ALL POWER IS REMOVED FROM TV. SAFETY FIRST.
Good Luck, big IRISH. PS after cleaning [place heavy plastic over effected areas.

Problems with my 50 inch hitachi ultravision projection screen tv


check the solder around the area of the vertical IC. solder is either cracked or else cold. Cold solder appears as dull. Resolder anything that isnt shiny.

Probably a 'cold or detatched' solder joint on a component on that perticular circuit board you are 'wedging' with a plastic rod.

Hitachi 43fdx20b blurred Picture


Yes this is a normal diagnoise. Just about every Tube type projection TV set ever made will one day need these IC's replaced. They are not really that hard to replace but you would need to know how to solder and unsolder on printed circuit boards, know the procedture, and then have a service manual handy to adjust the convergence after yoou replaced the IC's. If the tech works on alot of these types of TV sets's, most likely they could adjust them without having a service manua handy. This repair done by a pro should run you anywhere from 250 on up to 400 bucks depending on who does the repair and where. Good Luck
