20 Most Recent Hitachi 53UWX10B 53" Rear Projection Television - Page 9 Questions & Answers

I would suggest searching your Menus on the tv for the option to turn it off. Or search your manual.

most cases will have a parental lock on the chip which is set by the owner.

"Each television set’s V-Chip works a little differently. Once you understand the
definition of each rating and content label, programming and activating the V-Chip is
as simple as following the set-up procedure which can be found in one of two places:
1) the television on-screen menu options, or 2) the written instruction guide included in
the owner’s manual. The V-Chip will only be activated if you select the option to do so."

you can go in through the back of the tv to set the focus you should be able to converge the tv from the remote.if not i would call a service tech and have them come and reset it for you.

Check your TV back panel. If it has a DVI connector (like your monitor), you can get a HDMI to DVI cable and it will support both 1080i and 720p. My 57XWX20B has this connector. Good luck.

the tuner is where the cable hooks up on the back of the tv.its out and needs replaced.thats what the message means

some just don't have hdmi

it sounds like somthing in the optical asembly is mesed up and vibration causes it to get worse
with all the problems i would segjust a new tv because old parts are sooo expensave.

You have other little fuses that you can check in the power supply.In this model I think there are 5 of them.They are little yellow fuses soldered into the circut board.

you can try the convergence first
if you cant converge the lines into one to correct this then you would require service for the convergence stage of your set
this is not a uncommon problem and usualy runs around 280 to 350 to repair unless the dcu is at fault

Hello yorty,

You are the first person I have ever had to give this advice to. Let me explain, some folks "get lucky" and the replacement of the IC's and the simple alignment are usually enough, but in your case you have landed in the magical land of complete convergence adjustment.

You are going to have to perform a static and dynamic convergence alignment of your TV. in theory its very simple. here are the instructions:

First, you will have to adjust purity of the three CRTs (follow the instructions in your users guide or the schematic of your TV)

Second, you will need to set the static convergence of your TV (This will set the center of your tv and some of the side, top and bottom, lines)

Third, Once the static convergence is done you will need to set the dynamic convergence of your tv this will set the lines of the extreme top bottom and sides of your tv.

FOLLOW THE INSTRUCTIONS IN YOUR OWNERS MANUAL OR THE SCHEMATIC FOR THIS TV!!

Now for the bad news,

These three actions are all intertwined, That means that once you adjust one, you will have to readjust the others to match. Now this means that on an average, you will spend the next 8 - 16 hours doing the adjustment (8-16 hours are the estimated times for a TV technician to perform this task).

Now, I would suggest getting a TV technician to do the alignment becuase the task is very very tedious, and even most TV technicians hate doing it. I wish you well.

I hope this helps,

Thank you,

Hello steveandlill,

I posted this before, however I believe it fits your problem too:

You have a convergence amplifier problem. This is a common problem inthese types of televisions. The fix for this problem is to replace thetwo convergence amplifiers in your tv. These amplifiers usually go badalong with the associated bias resistors. I would suggest that if youare going to do this yourself you should use only the manufacturerecommended replacement parts. There are many who will tell you toupgrade the amplifiers, but my experiences have told me this is moretrouble then it is worth, if you don't plan on redesigning the circuititself. So with that being said, here is the basic procedure:

1) Get a schematic for your set (to be used in parts location and alignment instruction)

2)Using the Schematic locate the STK329-xxx or STK392-xxx seriesamplifiers (They are the two large six sided components attached to alarge heat sink on the deflection board)

3) unplug the TV set

4) remove the deflection board from the TV set

5)using a soldering gun or iron with either a de-soldering pump orde-soldering braid remove the solder from the pins of the amplifiersand the associative biasing resistors.

6) remove the amplifiersfrom the heat sink and clean the heat sink off with alcohol or asolvent designed for removing the silicon paste.

7) coat the metal plate of the new amplifiers with heat sink paste and install them on to the heat sink.

8) install the associative biasing resistors

9) solder all of the components, making sure not to create solder bridges (short circuits) on the printed circuit board.

10) inspect the soldering job for bridges and cold solder joints (touching the joins up if they are cold)

11) reinstall the board to the television (reconnecting all cables removed.

12) power up the TV and perform the alignment instructions in the schematic

13) set the alignment of the TV

14) perform the magic focus setup

This should complete this task.

Now if you feel that you can not do these tasks, please consult a qualified TV technician about doing this for you.

I hope this helps

sounds like a bad cap in the audio section.
have a tech look at it for you.

If you have a cable box, it may be set up for the full aspect. I just got a hd box for my 53" Hitachi and also notice the aspect dose not change using the remote. The guy installing the box was pushing so many buttons during set up I have no idea how to change without calling them. Hope this helps.

Hi, convergence circuit has failed, this usually involves two STK 392-xxx Ic`s and sometimes a couple of low Ohm resistors, If you are proficient at soldering and have an accurate voltmeter and a lot of patience you can do this, If you are NOT proficient at soldering call a tech or you WILL make the problem worse, If you decide to go for it e-mail me back and I`ll tell you a good place to get the right stk`s not the cheap chinese crap you`ll find on-line, BMW Rider

Here's a link for a west coast located Hitachi parts distributor:

Hitachi 65F59A Replacement Parts

Convergence ICs STKs replace both of them If they are STk392-110s up grade to 180s better ICs They are big black chips order parts at Electronix Parts 1-800-223-3205 you will need to also buy heat sink compound to put on back of new ICs.

You can't. Either it came with them or not,.....yours didn't. It's like wanting to make a black & white tv into a color t.v. Although I used to get that all the time.....It's just a tube you pop in!!!! Sorry, the set has to be designed in the first place with that.

Yes, it will work. Be sure to use input 4 with the 3 rca input cables red/blue/green for video and 2 rca red/white for the sound. You need component video output on the PS3. http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&langId=-1&productId=8198552921665061579&storeId=10151&INT=M:ak is what you need, if you don't have it already. Here's the thing. The PS3 will work on any set. You can hook it up with the yellow wire and red/white wire for standard def. or 480i. The component cables are for 720 and HDMI for 1080. Your set don't have HDMI, it has component input. The service manuel say's it has 720I available. You can see if the front has HDTV sticker..if it does, them for sure it does. Either way, the PS3 will work on your set. I'm 90% sure it's 720i as well.

Hello diduni,

Yes you can use them but read this first:

I could not have said it better myself, I keep this around for times like this.
The various IC's have different specs, one important one is the quiescent current. The higher number STKs have a higher quiescent current (+10%) If you replace a STK 392-110 with an STK 392-150 the small value resistors will "smoke" in many cases and have to be changed with different values. The different TV Help blogs are full of people that have put in the "new and improved" ICs then asked what to do now, all the resistors have smoked or the unit will not start. Hitachi has considerable information on the use of these ICs. In all cases they tell you to change the resistors for different values, to allow for the higher idle current. They also include information regarding alignment for minimum idle current in the circuit. This relates to height, width and hor/vert centre.
The design of the TVs is ok, the IC's fail from AC power bumps or lightning (accumulated damage to junctions over time). Semiconductors will run forever if they have a smooth DC power source, are ventilated to operate within temperature specs, and not overdriven. This was demonstrated when com satelites were first used. They had estimated electronic failure in 4 to 6 years and many last 20+ years. They are replaced when they run out of manouvering fuel or get an induced power surge from the sun. When the IC's run too "hot". there is usually a low ohm resistor that has increased in value and causes higher current output from the chip through the feedback in the circuit design. The resistor(s) may have changed from 1.8 ohms to 2.5 ohms, the TV will still run, but the IC will fail prematurely.
STK 392-110 will work fine if all the small value resistors are ok and the TV is not subjected to a hotter environment than normal or power line related troubles. Many RPTVs are mounted in enclosed areas with no air circulations or in direct sunlight. These situations will cause the unit to operate at raised air temperature around the IC's resulting in more failures. Some people have "hotter" houses than others, their convergence IC's will fail sooner.
If you can redesign the convergence circuits and waste your time replacing all the low ohms resistors, go for it. Otherwise use the STK 392-110, or whatever the manufacturer had in the unit. I know from experience. When Hitachi came out with "new and improved" replacement ICs we installed many STK 392-120 for STK392-110 in Hitachi and other makes. The result was many burnt resistors, many call backs and big expense. The same applies to the Samsung STK392-010 or STK392-040. Use the original IC.
