    Hi.



    Very strange problem your all having.

    The guy who says one ic is getting hot this is mormall im concerned about the cold ic.



    Ok all of you who cant move the blue try swapping the ics over and see if blue now moves properly but the red doesnt if this is the case then there is either a problem with one of the new ics or a problem with the circuit.



    As I said I have never had this problem after replacing the ICs but will try & see what I can find out.

I have a Samsung Rear Projection TV with an HDTV 1080i Monitor. I know the convergence is messed up because the blue would not move when I tried to adjust it on the menu. So, then I tried to make it


You will need to replace both convergence Ics and the pico fuses that blow when the Ics fail. You can get the replacement Ics and pico fuses from www.tvreairworld.com they also provide free tech support to help you install them

You will need to replace the two convergence ICs and then check and possibly replace the pico fuses on the D board and G board. The Sony number one convergence repair kit available from www.tvrepairworld.com is the correct kit for your model. The kit contains both ICs and the 8 pico fuses plus the CD with detailed repair instructions.

Convergence problem philips rear projection tv.


All convergence circuits require two voltages which are equal, one being positive the other negative. Check the power supply for these two voltages and then see if you're getting them at the output ICs. I suspect one of them is missing or low. If there are no cooked resistors near the ICs, inspect the fuses that protect those two voltage sources or the regulating devices themselves.

Samsung pcl5415rb convergence problems


If you bought a kit from sites such as TvRepairKits.com go back and ask for help. If you bought the parts over the internet without instructions you have two common problems...1) Bad/Fake chips... or 2) You did the repair wrong - because you lack proper instrucitons.

Pico fuses - yes - they can be one of many secondary reasons convergence is not fixed on Samsung models.

Sony projection tv convergence issue


You will need two STK392-560 Convergence ICs and you will also need two of the 3.5 amp pico fuses as Sonys will always blow at least two of the Pico fuses. You can get replacement ICs and Pico fuses at the fiollowing link and they provide free instalation instructions. Heres the link.
