Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

Convergennce We were given a 43uwx10b for our handicapped son to use with his xbox.  We cannot get the set to converge with the "magic" convergence. The set has been "kitted" and it looks like it was a butcher job.  Is there a place to buy the whole board inexpensively?  We do not have very much money to put into this set.  Thanks.

How do you line up bulbs with remote

This set with front grill removed has a tiny blue button on front edge of chassis on left side that will manually take set to convergence mode but you must have the Hitachi working remote to do adjustments---different buttons on the remote adjust and save the adjustments, I have the Hitachi book that shows all remotes they use and which buttons do what---if convergence is real bad most likely the two chips for convergence need to be replaced if Magic focus will not help.

My tv has a bow in it every time a banner comes across

It is not unusual in these sets for things not to be perfectly straight---if the set has recently been repaired for a Convergence problem--someone may not have adjusted it correctly.

Understand: if it is a 43uwx10b Hitachi:

The green convergence is adjusted first for a grid of straight lines up and down and left/right---if the green grid is not straight you are going to see a bow when things scroll across the screen.

The other possible problem you may have is a convergence problem--if you go into the customer menu and try to adjust convergence--not the magic focus-- are the blue and red adjusting or not?

I know the HItachi sets very well--I own two of them and have repaired hundreds of them.

Manual Convergence adjustment on Hitachi 43UWX10B

I would guess you missed a open resistor--there are only about 12 of them--how did you check them?

This set (43uwx10b) has a tiny blue micro switch on the front of the chassis---if you engage it from the front the set will go into the DECAM or convergence mode--let me know the CLU number on your original remote and I will scan and paste instructions---98% of the time if the set is wacked out and will not adjust one of the resistors is gone---ONE OF THE CHIPS GETS THEM.

42 inch Hatachie Ultravision model 43UWX10B and

The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----

Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

The magic focus is not helping

If the magic focus is not helping then the convergence amp IC's are probably burned out.

HITACHI 43UWX10B Color Convergence

Good Day,

Sounds like the TV's convergence circuit has failed:
*Call an Authorized Service Center and them give you an estimate cost of the repair, or
*Repair it your self; get KIT 10 locally or B&D Enterprises
Good luck, big IRISH.

Magic Focus does not work.

Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
with upgrade Stk394-160E Hitachi part # CZ 01341,change both
for reliability.....check B+ feed resistors for over-heating....T.
