20 Most Recent Hitachi 43UWX10B 43" Rear Projection Television - Page 7 Questions & Answers

Sounds like the light engine is going...costs as much as a whole new set. May have to get a service man to have a quick look at it to be sure. Scrap the set if it is the light engine and buy an LCD or Plasma. They won't last as long as this set did...

Change the two ICs stk 392-110 and check the resistances .

its a bad capacitor , go to www.youtube.com and you can search for projection televison capacitor repair . and it will pop up with all kinds of video's for you to show you how to repair it yourself with a little soder and a sodering iron.

Ur convergence is dead.Must replaced 2 convergence ICS,and some or all it resistors.U know to solders?Tries websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300 for parts and labors.

Hi

Possibly but that depends on your antenna. What you will need to do first is change your TV's input selection from cable to ant. Should be in your menu.

Ur captioning is on.When u turn into the channel have captioning,that why u have words,or symbols.Check ur remote have a CC button.Press it make sure it off.U will not get anymore black boxes with letters or symbols.

These chips are the culprit:

the convergence IC's

Replacing them requires a lot of soldering and a knowledge of circuit boards.

Is the TV worth saving? is it bright and clear? was it good (when it worked?)
ifthe answer to all of these is yes, then you have a few choices. If anyof these are not true, then you should just get a new tv.

Your choices are:
Ifyou are good at soldering, then you can attempt to replace the IC'syourself. (with all of the parts handy, it should take 1 hour)

Ifyou aren't good at soldering, then you can have a friend do it for you,or you can have a mechanic fix it. (tell them that its the convergenceIC's that went bad. (pay no more than $200 for the job).


Thesego bad on almost all projection tvs eventually. They overheat and burnout, causing the screen to go in/out of alignment and make wavy lines.

If you need more info on IC's, contact me.

Thanks for asking!

The problem I had with mine was that the optical drive went out. Another 500 bucks + the 400 dollar bulb. wiped out my warranty in one swipe, then they paid me off with the rest of it. The picture quality was excellent and I loved the sound. You are better off cutting your losses.

matt electronics. make shure you get the exact replacment stk ic.s those are prob. stk-392-110 or 120 also check that no resistors are opened on the convergence module good luck

stk ics are bad on convergence module also check resistors when you replace ic.s

I know these models came out around 2001, and I'm afraid that the problem sounds like it is related to the bulb going bad.

This article outlines how many TVs from around the turn of the century have had similar problems to yours.

I know bulb replacement is an option. You may want to call around to TV repair shops and see what your options are. In the end, though, it may be time to start saving up for a new TV.

If you try to adjust convergence with the flash focus, perfect focus, (depending on the make of your set) or by manual convergence and the lines will not line up or even move. What you might be experiencing based on this symptom sounds like a convergence IC problem.
I have repaired hundreds of these sets, so if you have any questions after reading the following, please reply to this post and I will help you in any way that I can.
With any Projection Television that has a damaged convergence problem, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.

With that aside I have some support suggestions that I have put together that may help you make an informed decision.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00, If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky

How do I tell if the IC’s are damaged?
When looking at the area around the convergence IC’s you see some resistors that have changed colors, or you test a resistor and it no longer reads the marked value. You will have to replace the IC’s and the supporting components.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.


Where are the IC’s located and how do I find them?
There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , they do carry OEM or better parts.

I have attached some photos of really bad convergence problems; your picture may not be exactly as bad as these.

it have red ,blue,yellow lines

you need to replace the lamp you will need to know the model# you can find it on the back of the tv

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Replace both of your convergence ICs they are big black ICs will have STK392-110 on them Call Mats 1-800-628-1118 10.95 each.
