Problems with Hitachi Ultravision 53UDX10BA rear projection television!!!!!!!

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size

My tv has double picture how do i fix it

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
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.

Tv screen does not come on and there is a high pitched "whine" from the rear of the TV

That is a 400 dollar part and it has to be special ordered.

Removing the JK07132-A convergence board

Unplug TV from ac outlet for few hours, this will discharge caps in circuit boards and you can take out desired board after unplugging connectors.
Always Be Careful while doing repair in TV.

Hitachi ultravision rear progection converge

If the convergence is so far out that you cannot adjust with your customer access menu then You will probably need the convergence ICs replaced & possibly a fuse or resistor or 2. Then a complete convergence will be necessary & I HIGHLY recommend having a professional technician perform this task.
