Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

Philips 43pp9202 I got the same problem with my rear projection and i replaced the Ics STK 392-150 and the resistors over-heat ( at the beginning they were for the blue color proyector). when i changed everythings and turn on the tv again, the resistors for the green color projector got over-heated, and for the deflection problem, before it was the blue one now it is the green one. My question is : why are the resistors getting over-heated ?

    Thanks for your information Terryfic. I'm sorry i did the question when was reading the same problem, but in a Hitachi t.v. My question is: Can i use the same part X480293 on my Philips 43pp9202 ?

    I Was looking for the ic's STK394-160E by Sanyo but they say that it works for Hitachi Tvs only.

    Thanks Terryfic for you information about Philips - Hitachi. I did start again using the STK394-160E (CZ01341) and i changed the resistors for Philips (6.8 Ohm 1W ). Everything looked well. The display is showing, but the convergence is Terrible. All the colors are bent out of line. and when I tried to fix the converge manualy, the convergence setting doesn't respond. it stays fixed in one place. What could be the problem?

Because the STK's used were not first quality....For STK392
-110,-120 and -150's I use STK394-160E made by Sanyo with
Hitachi part # CZ 01341 or you can buy a kit of two IC's and
some resistors ( Hitachi application ) for less money. Now you must start again............................T.

    I use the Hitachi kit for Hitachi, Toshiba, Philips and any others

    that use -110,-120 or -150 original IC's......just keep in mind the

    resistors in the kit are specific to Hitachi chassis'............T.

    Your TV was made by Hitachi with Philips name on it !!.............

    Check fuse devices in power supply...soldered in pico fuses....

    Check voltages that operate convergence,they flow through the you have Service literature ?

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.

Its a straight forward repair just take out the convergence ICs and solder in two new ones. takes about an hour from beginning to end. just apply heat sink compound on the new ICs before installing them. And in that model check the resistors right next to the ICs as 1 or 2 of them often burn open when the ICs go out. Let me know if you need any additional info. The ICs cost about 10.00 each you will ned two.
