Why are you spending so much! you could get the board repaired for a fraction of that
or do this yourself.

53uwx10ba.....seeing double/triple, colors primarily red white blue...can we fix this ourselves? and does the front of the tv come off?

Yes,but the front that not what u wanted to be open.The back of the tv that what u wanted to be open.That where the tv convergence board is,that the board require reparing.Yes,if U have all the tools and can do basic soldering works too like take out desoldering ICS take it out of a circuit board and resoldering ICS on put in onto a circuit board and also desoldering/resodering like take out small components parts and replace with new small components parts onto a circuit board?Yes?The tv convergence board must require replaces like 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.Tries websites like, to buy a whole complete convegence kit belong to ur tv make and model the kit also will have a dvd disc of tutoring job too.Or tries tvs shops will cost u like $300-350 for parts and labors.

It appears that I'm seeing 3 images red ...yellow and blue, it's like they're not in sync with each other, it was working fine and then poof!what do I need to do to fix/ I don't know the year or model #,...

Most common problems belong to the DLP tvs design.The problems u having are commonly call the convergence problems.The tv have it R,G,B colors lines mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board the 2 STK convergence ICS and some or all of it resistors are dead.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.U have tools like a soldering iron,desoldering pump or desoldering braids,solders and a know how to do basic soldering?Yes,than u can tries websites like, to buy a convergence kit to repair it ur self.Or the shop,will cost u like $300-350 for parts and labors.

Tv all of a sudden starting showing everything in 3D picture outlined in green. The model # is -53x54j the serial # is LY43060344. The tv was manufactured on November 2004 and that is also the month and...

What you have is a convergence module failure. This involoves two boards known as the Sustain Boards. However the power board may also be involved.
Manufacturer recommends that all 3 boards are replaced as they compliment each other. It is not a DIY ( board swapping is not like PC these boards have to be tuned to each other and require special tools and circuit Diagram to check voltage points
I think you are lucky to have had it this long without failure. Estiametd cost for parts is $300 + labour. Alomost not worth fisxing, as standard televisions can be bought cheaply from second hand dealers quite cheaply and have a 30 nday warranty

Red light blinks no picture or sound

took the board to friend who works on TV's.he tested the board and replaced the 2 black IC's #STK 392-040 .I re-installed the board and TV so far is working fine. hope this helps !

Blue and Yellow lines showing up on the screen.

STKs cost no more then 19.00 each they have them replace both ICs use 392-180s better ics 100 percent holdup rate. they are big black ICs retail on ics 55.00 each

You need to re-solder the circuit board that contains the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall, about dead center in the circuit board. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. This is a caused by a minimum effort (a.k.a. minimum cost) solder job, probably done in some 3rd world sweat shop. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conduting piece of wood to push the heat sink when we doing tests. Best of luck, hope ya fix it. If that doesn't work the nodules need replacing.

You will need to replace the convergence output IC's and check the resistors in that circuit.
