Hi,
The problem is your convergence circuit board gone bad. This is commonly caused by shorted/open IC on that board. First try to spot if there is a bad solder joints and resolder it. If nothing replaced the convergence IC. Also check the resistors around.
Hope it may help you.
Have a nice day!
Thanks for using Fixya.

My samsung rear projection tv has a problem with its convergence ic. i think theres two ics , but how do i tell which ic need replacing??


Always replace both once your going to the trouble each IC is usually less than $30.
This link will help show you what's involved.
convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

I have a HCL473W with a 'concave' screen effect on 2 colors??


You don't need to replace the whole board, regardless of which board it may be mounted on. The STK IC convergence chips alone are all that need to be replaced. You can order them from a number of different online sites. You can try Alibaba.com. If you have any more questions, feel free to ask!

Having Problems getting my tv to turn on


It could be a Flyback transformer problem. Check th flyback for loose solder move the transformer a little bit and look on the underside of the circuit board. be careful ther may be current left over. Put your left hand in your pocket.or away from you. if it is not that you may have a faulty circuit board (burnt resistors) near the yoke going to the screen.

Hmmm... I dont know where to find those CTR Circuit boards I'll post my general post for you about what I know it has links to the manual and some other sites it may help.

how bad is it burned, did some chips go or just the copper circuit board tracers. you can use circuit board wire and solder it from point to point,
I had somewhat of the same problem with my IC board, I had a bad portion of the board where I had to build a new copper routing with circuit wire, the copper burned off when the resistor failed, you may need to do a little Frankenstein work on your board as a last resort... remember use a low 15 watt soldering pencil, use leaded solder, and USE flux!
however with all my work, I got it running but the IC board is still not running perfect. if you decide you cant fix the TV I would love to buy your IC convergence board from you.
GOOD LUCK! hope I helped...

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com
