Hi Javier,
Please let me know if you can hear the click of the relay upon powering on the unit and if the red light lit is on solid or blinking. Also observe if the led light will turn on green or just red light. It will help diagnose where the exact fault came from.

Hitachi 53SDX89B is September 1999 model as its mentioned on its service manual that I have.
Since tv is too old so I'm afraid, no spare boards or parts would be available any more to fix its AC leaky current issue that damaging ATT U-verse service. (power back feeding out, we call it AC leakage).
There is one solution for that problem, buy Isolation Transformer and plug your tv in it, that will cure AC leakage from your tv and wont hurt any thing attached/ connected with this tv. Your tv consume 245 Watt power while working so 500 Watt isolation transformer would be good enough to keep turn On tv for hours/ days.
Below is an image of basic isolation transformer and click HERE to get required 500W isolation transformer.
Hope these info will help you.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.


They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

If the problem is exactly like before one of the protect resistors is bad.

The color bands denote value in resistance and usually it will be a 1.2, 1.5 or 2.2 ohm resistor. You check them with a ohm meter, like checking a fuse--any that has no reading across it is gone.

Usually they will be discolored but sometimes they open so fast they do NOT discolor.

There are only about twelve of them and many are higher values--150 ohms or more==always it is a low value resistor that opens--it is what it is there for--a chip shorts in some way and the resistor opens to protect the power supply that feeds it.

Looking is not always enough, you have to check them. If this is helpful a rating would be appreciated as I do this here for free.

I am available to assist you if you need it.

Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of anly a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

Discharged Flyback Transformer. Removed main pc board from bottom of TV and flipped over, no apparent damaged components or blown board traces were found. Noticed a lot of flux in various areas on the board that seemed unusual (maybe TV was worked on before as I bought a showroom demo at Circuit City). Used a plastic screwdriver to remove all flux between connections on ICs, Transformers, Flyback Transformer, and various other components. Cleaned all debris, dust and crud accumulation (TV is over 10 years old and there was alot around the Flyback Transformer) from both sides of board using a lightweight paint brush.
Used a magnifying glass to check all solder joints for possible cold solders and found none. Did the same for Power Supply Board. Checked various ICs and Power Transistors for opens or shorts (in machine) and they seemed fine. Reinstalled boards, said a few Hail Mary's and fired it up.

The protector Led no longer flashed under power and lo and behold I got picture and sound!

I cleaned the lens on the projectors (again 10 years of dust accumulation) did a magic focus adjustment and it works fine!

After reading other fixes, I fully expected it to die after 10 minutes so I left it on all day and against all odds it still works.

What was the fix......Dirt buildup on and around Flyback and other components,,,,,,Flux conducting electricity between contacts on Flyback and other components.....or oxidation on connectors between Power Supply and Main Board.....I don't know.... all I know is that for the moment I saved around $ 300 - 400 in repair bills by doing it myself.

have you opened up the rear of the set and located the "COLOR-GUN" controls for the RED/GREEN/BLUE output guns, they should be near the rear apron on the back of t.v. set,adjust till colored lines just disappear then up till reappear and back again, do this slowly so you don't have a drastic voltage voltage variance all at once

Hitachi 53SDX89B... | Answered on Oct 17, 2009

Symptom shows that TV has problem in deflection section and most probably convergence output ICs got heated after TV powered up and causing red-green strips. Due to excessive current drain in these 2 ICs, picture becomes smaller too.
I would check Convergence Out ICs temperature and if its getting over heated, will replace both of them.
If you are comfortable with TV repair and can sold electronics parts in circuit board, let me know to provide you more technical info.
Required Convergence out ICs (STK394-160) are available in Part Store, click to see an image and price info.
Service/ Repair Manual is available in Manual Zone for small fee, if you need to fix TV.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

DId you Try replacing the bulb?

Hitachi 53SDX89B... | Answered on Feb 27, 2009

I have the same thing and just bought a replacement being delivered this Wed. It kills me to just discard it but I have looked on the boards and don't easily find the convergence IC to replace. Not a tech by any means but it looks like parts should be under $100 IC's seem to around between $20-30 each and I believe there are two of them. I have a link on how to replace them on another model but unless I am blind they are not on the same place on our model. FWIW here is the link if you want to check it out http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm.

I also can not take credit for the link and would gladly give the people credit but I can not remember where I found it........another senior moment lol

Dave, HMMMM Dual pictures This is a problem that every projection TV runs into at least once or twice in its lifetime. Its the old convergence IC falure thingy. These IC's go bad and should be replace all at once. These are not consumer replaceable unless you have had training in the electronics or TV repair fields. Please call out a pro to assist you with this repair as A TV is not the place to experiment in because of the HI voltage and saftey issues. Good Luck

luckyly here are tech that have knowledge of electronic,if you dont whant any boddie ripp you off, well this gonna help you. Definitively, your set have a short, in the power supply or in the horizontal circuit, with this in mind request to varius tech an estimate, and what, they think is the problem, then you can take a good decision...good luck

Hitachi 53SDX89B... | Answered on Aug 06, 2008

The alignment you need to do to realign your TV is called "setting the convergence". All projection TV's have 3 color guns (one red, one blue and one green). When you move a TV or josstle it, these guns can get misaligned and need realignment. This is definitely something an average user can do (you don't need a TV repair man to do it for you). It is a very simple procedure (most TV's have an option in the menu to do this, just look for convergence adjustment). What you want to do is use the remote to get all 3 colors to overlap completely (you can only move one color at a time). Some TV's have squares on the screen that you must align, others have plus signs. If you can't find it in the menu on your TV or if you can't figure it out on your own, you can look for a manual at Hitachi's website that will walk you throught the process for your TV.
