Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

We have a Hitachi Rear Projection Color TV, 53UDX10B, which we've had for about 10 years. Just lately when we turn it on, there is either no picture or the picture is very small and distorted in the center of the screen or the screen flashes. After a while, it settles down, and we have a normal picture. Is this TV repairable? Thanks. PW

Yes, it is repairable but if you keep forcing the set on then chances are you are going to make matters worse to many people wait untill the TV will not come on resulting in damage to more Parts Right Now if you know how to solder you need to resolder the power supply board and if the STK ICs have never been replaced ,they am sure are due to be changed STK392-110s use the 120s. Mats Electronics has them $9.95each 1-800-628-1118. You need to have this matter tooken care of Soon. See if the ICs just need to be resolder also,before replacing them.

if you have no pic from your coaxial inputs then your tuners are bad and need to be replace but you can bypass them by using your a/v inputs which do NOT go through your tuner

Good Day, techAlmost;
You may able to repair this yourself if you are good with a soldering station (gun). The KIT 10 contains the IC's, resistors and simple diagram for the repair.
If not handy with soldering call an Authorized Service Center and have them give you an estimate.
Good Luck, big IRISH.

Scrolling lines in the picture

The capacitors in the sweep supply and maybe in the main power supply are starting to dry up. Your going to need to get a tech to go over the boards and search out the dryed capacitors. It will take some time and maybe a bit costly. May want to think maybe about a new set? Good Luck
