Seeing multiple images

CONVERGENCE PROBLEM. FIND A HONEST TV TECH. MAYBE A $300 REPAIR

It is most likely the convergence board. Rear projection TVs use three lights to display the image. The image is aligned via the convergence circuit. After many many hours of use the capacitors and resistors on the board lose their tolerances. It is very expensive to repair if you take into account the price for a new TV and the quality of the image you will be getting if you do have it repaired.

It is a convergence problem.

Tell me brand and model number and I will tell you what is needed or if it is reasonable to repair.

SD TECH

if your talking about the sets convergence does not line up and it looks like a 3-D picture than The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
The kit comes with original Sanyo STK IC'S , not those cheap aftermarket or china made IC'S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

Ur convergence is dead.Must replaced 2 convergence ICS,and some or all it resistors.Must know how to solders?Tries websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will $300 for parts and labors.

Hi,
It would be great to assist you in Sony convergence issue.
As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder.
There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV.
Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time.
Let me know if you have additional question.
Thanks.

The problem you're having is due to the failure of the convergence amplifier circuit. In that circuit are some components which amplify or control the signals to the dynamic convergence yokes, which line up the red green and blue images to superimpose them over each other to create a proper colour picture. When you get a failure in that circuit, it no longer aligns the images properly, and generally you get what appears to be badly set geometry in multiple colours. In some cases you will also get a problem with the part of the power supply that supplies the convergence amplifiers, or the digicon, which is the digital convergence control module.

Just to clarify, it sounds like what you are saying is that the image appears to duplicate in either red or blue along the edges of the image (especially white lettering and probably increasing along the boarder of the TV). This is resolved by converging your TV. Convergence will drift normally on large screen projection TV's over time or through moving them. The Hitachi 57f500a has a feature called "Magic Focus" (pg 36 in your manual) which will auto converge the image. If the auto converge feature doesn't work, on page 37 in your manual, it explains how to converge manually. If you do not have the manual, I have the image of the pages below. If for some reason this doesn't work, please provide additional info and detailed prior to rating the help.

If these colors appear to be like a 3-D image, the problem is in the convergence circuit. Please update this with the make and model and I will provide you with further information and instructions.

Thanks,
Dan
