It sounds like your Green CRT ( picture tube ) is shorted. That's the one in the middle. Sony had issues with there tubes in those years. Sorry for the bad news. Even if you could locate the tube, it will be a matter of time before the Red or Blue does the same.

moz-screenshot.pngmoz-screenshot-1.pngIt sounds like your convergence is out of align. You can adjust it manually. Its on page 16 of the manual. If you don't have the manual its on the sony support site. I hope this helps you.

If by blue shadows you mean that the colors are not lining up, then I can help you as I have seen this problem before and have repaired hundreds of sets with this symptom.
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 damaged convergence IC.
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. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

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.

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/ , I have not tried them yet, but they do carry OEM or better parts.

With any Projection Television that has a damaged convergence IC, 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.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Thanks for using FixYa

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

If you have a CONVERGENCE problem and it will not adjust---the two STK-392-150 Chips this set uses need to both be replaced and the set adjusted with the original remote control.

You can, if you are able to do the repair, buy a pair of chips for less than 14 dollars plus shipping on Ebay.

If you cannot do the repair--shop around your area--most shops are going to charge 300 or more for this kind of repair.

When you consider the cost of the parts--if you can do it or know someone who can--you can save the set and a lot of money--This repair can easily be done right in your home in about 1 hour--I know as I have done hundreds of them---did two today.

The chips (with the back off of the set) should be on two metal heat sinks on the board on the far left---they will be facing the front of the set.

All that is required to get at them is to remove all the plugs on that board and the screws that hold it in and tilt it up so the bottom of the board is in view---you unsolder both chips (about 18 pins each) and remove the 2 screws that hold each to a heat sink.

With 2 new chips you put heat sink compound on the back of each--it is a white grease to move heat quickly from the chip to the metal, and solder both chips in----put the board back down and all the plugs back(I usually mark all of them so I know where they go) and turn the set on and see what you have...

Most of the time this repairs the set--go into the customer menu and adjust the convergence and you are ready for another 5-8 years of life---this is the normal lifespan of these chips.

If you need assistance or have questions let me know--I am here to help people.

not all the time i think you can access the menu by pressing both of the volume buttons together at the same time or the channel buttons together at the same time...its one of those and then you can navigate up and down by those buttons as well

Sony KP-53S65... | Answered on Oct 22, 2009


use the perspective button on the remote. or aspect, or aspect ratio, whatever it is... it is definitely on the remote.

You need to get into service mode if flash focus does not work. Of course you have to fix the convergence problem first or neither modes will help

KP53S65 is a rear projection Sony several years old--It is not a DLP and does not have a bulb--it has three picture tubes---if the set has not been serviced in a long time here is what you can do to try to improve it:

1.) Unplug set
2.) Remove back cover
3.) You will see 3 black lens (one for each tube)
4.) With a paper towel (spray glass cleaner on it) clean the dust from the three lens---if they have not been cleaned in a long time and have dust on them the picture will be darker and less distinct.

5.) Replace back cover and plug set in to see if this has helped----I have seen some where there was so much dust on the lens that it looked 50% better after just cleaning the lens--depending on area you live in--should be cleaned once a year.

I do this here for free so if this has helped you please take a minute to give me a vote here.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

just look for the rating of the capacitor..it's voltage and capacitance...any electronic parts store has sit..just replace the capacitor..

The convergence amplifier responsible for blue is dying. Soon blue will be off all over the screen when it fails completely. Only solution is to have the convergence output IC's replaced.

Replace the convergence ICs. you will need two of them. They are located on a large aluminum heat sink with STK numbers. They cost about 10.00 each. They need to be soldered in. Its an easy repair if you can solder. Let me know if you need any additional info.

Sony KP-53S65... | Answered on May 09, 2009


It sounds definitely like a faulty power connection via the video cable from the inside. If it blinks a while then turns black then shows the picture, it would have to be that it's not screwed on properly, thus taking more time for it to get a full charge and then properly function. If you still have the warranty, any electric repair/retailer shop can fix it for you.
