  • wolverines01 Jul 25, 2008

    i looked i order stk392110 and ther were not the right one we found that out she said the i need a ic amp

  • wolverines01 Jul 25, 2008

    this is what she said maybe you know something more



    Ok that chassis is from 1987 thats a classic. That is going to have one large Ic a STK number that powers the convergence unit, and that board way over to the right attached to the side of the set has all the heat sinks on it? The transistors on those heat sinks control the individual movements of the convergence controls. So your main IC amp is whats needed. Can you give me the number off that large IC with a STK number on it?

  • wolverines01 Jul 25, 2008

    the model number is fp5240 w101

    Thats usually the case of a failed convergence IC when you get the arcs at the top and bottom of the screen

    without the model number there is no way to tell unless you take the number off the ICs . If its a HDTV its a DPTV chassis with two STK392-120 ICs if its a non HDTV it has two STK392-110 ICs. If it has only one those are from the 70 and 80s so they had different ICs they used so you will need the number off that IC to tell.

    Thats an old chassis that one uses one single IC then about 10 other transistors on a seperate convergence board. I am not sure of the part numbers as that has to be in the PTV 6 or 700 series rear projections that was before they started using two ICs to bypass all the single transistors.

I bought a brand new 42 inch plasma vi vo tv 2


New products do fail. The set should certainly be under warranty. I would speak to the dealer you purchased the unit from and see what they suggest. Don't remove the rear cover, or do anything else to give anyone a reason to void your warranty. Most brands are 90 days on parts and labor.

RCA BIG SCREEN TV WONT TURN ON HELP !!!!!!!!!!!!


Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.

If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.

Usually when devices power themselves off like that, there's something wrong...

I hope this helps :) Good luck!

Best Regards,

James

sounds like you need to have the two convergence IC's replaced. These are soldered on the main board. Good Luck
