which board are you needing that model has alot of boards in it such as the G board, D board, A board, B Board, and etc. Let me know the symptom or which board and I will assist you with the issue.

Thats a convergence error. Your model will require the two Convergence ICs and also 8 pico fuses 6 3.5 amp and 2 5 amp picos. Of you require a repair kit with the parts and instructions you can get the Sony type 1 convergence repair kit from www.tvrepairworld.com which fits your model.

It sounds more like the green CRT has an issue.

a SOLUTION is that someone is going to have to replace both the STK392-560 CONVERGENCE chips this set uses, there are a few other parts around them that can fail but for the most part just the two chips need to be replaced and the set adjusted, parts are fairly cheap but it takes some soldering skills to do this repair.

I can tell you where to find the parts etc but what is your skill level ???

Let me know, I can step you through the repair and I also have skype IM if needed.

The Green CRT has shorted and will need replacement. You can verify the problem by removing the Green CRT drive board from the green CRT dont unplug the wires just slide the board off and let it hang suspended then try powering up the set if it stays on without shutting down then you will no its the green CRT for sure. You can get a green CRT from www.tvrepairworld.com

one or more of the CRts have a problem and will need to be replaced. Removing one crt drive board at a time and trying it will isolate which CRT has the problem when the set stays running after removing the board from the bad CRT.

How many times does the light blink as thats an error code indicating which circuit has the problem. Let me know how many blinks and I will assist you with the problem.

Ur tv have a problems known as a convergence problems,it is dead.The tv convergence board must be repair by replacing 2 STK convergence ICS and some or all of it resistors too.To fixed tv 3D or misalignments R,G,B colors lines tv picture.Are u willing to put in another like $300-350 for tv shops to fixed?That what it will cost for parts and labors by a professional tv tech. to do the job wright.

try cleaning the filter. sometimes when the filter is dirty it heats up fast and shuts the TV down.
This is because the video ic is heated up and automatically shuts down to prevent overheating.

You need to replace the convergence IC's in the set. Part number STK 392-560. Two of them. They have to be unsoldered and solder in new ones. You must have advanced experience to get the job done. I suggest you get a TV technician.

check manual for how to COVERGE or CONVERGENCE- sounds like your red and blue guns are out of alignment

d_schwartzz,

Go to this site http://www.apwagner.com/index.php?main_page=product_info&products_id=2591595 It is not clear whether they are available or not but everywhere else they are out of stock and no longer available. Another option could be Ebay although you may not know what you are getting. If you find one I have a tip at http://www.fixya.com/support/r4573850-change_crt_in_projection_tv which explains the remove and replace/adjustment procedure.

Thanks for using FixYa and for the great rating.

What exactly did you repair? Some fixes on line dont delve into the cause why the component failed. usually if a component fails just replacing that component wont fix the set unless you diagnose what caused that item to fail. Let me know what you fixed and I should be able to help you out with the problem.

Yes,the tv problems it is the same,it is the tv convergence problems again,now it just color it is shaded in shadows pictures,instead of wavies mis colors R,G,B mis alignments.Yes.The tv convergence board it is the problems,must be repair again.

How many times is the light blinking in between pauses? as that is an error code.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• 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.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

When the standby/lamp indicator lamp flashes 3 times, this is an error code that generally means the set has detected a B+ overvoltage protection condition. some common causes of this are faulty ic's (intergrated cuircits) 500 and or ic 5002 these are both located on g board and generally i would replace this board. the last repair i did of this type ran the customer around 275 depending on cost of part.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

That usually means your convergence ics are going out. Replacing those will get rid of the double imageing. If the color is faded realy bad that means your tubes are going bad. That repair is pretty costly. Tvs over ten years are usually money pits.

This is commonly called convergence. There are several problems wich cause this the first and main cause of this if falure of what is called the convergence amplfing chips.. generallly two large microchip that get hot and short out. This ussaly cause other components to fail too. the price of these chip gennerally run around 50 to 100 a peice. i repair of this type run around 150 to 200 depending on the shop you go too.
