Replaced IC chips and fried something

Hey guys, I replaced the IC chips on my PT 53W53G and I fried a couple of resistors, Must have melted or crossed something. IS it worth getting this fixed? Can you buy a complete board?

    Replaced the convergence chips, and when I turned the unit on two of the resistors right near it smoked.

Have a Panasonic PT-47WX53 47. It's probably as old as when it came out. I've messed around with the convergence before but it was never un-fixable. Then a couple a days ago I came into the ro


yes and also possibly the low ohm resistors. You can get the PT53WX53 convergence kit which fits your model from www.tvrepairworld.com which has the 2 ICs and associated resistors plus the CD with repair instructions.

How do you fix the color to a model 43fdx11b hitachi


Hello!you mean: colors out of convergence? nothing you can do about that, unless you replace 2 convergence amplifiers I.C. chips, plus all those burned 1 watt low ohms resistors with exact values, which only could be obtained via service manual or schematics. After resistor is burned, there is no way to read color code properly, due to partial evaporation of pigments. this is a "pro" job. If you try or tried, already to converge those "stubborn" crosses, there is more to do, even after you removed and replaced two 20 pin I.C. chips, soldered dead into sweep module, plus located and replaced resistors with precise values, you need to get your settings back to normal, by going into "factory service mode' or, at least into "convergence alignment" menu and fight with those crosses!Don't forget the white "****"! Otherwise, you will be re-servicing your set all over after 30 days of usage.good luck,Alex.

My t v pictures are sharing colors


if its a pt47wx53 it sounds like the 2 convergence Ic chips are gone--also--there are several blue 2.2 ohm resistors around them---if any are discolored you will need to replace them also---this set uses two STK-392-110 convergence IC chips---you will have to remove the light box---I can tell you how--look for the convergence ic's inside and take a close look at the 10 or 12 powder blue resistors around them---if any two are white in the middle(discolored) they are gone--if you need any help let me know.

Continued convergance issue.


I have heard from a few people that the higher value IC (150, 180, etc) do handle more current, but also that they *draw* more current, as well. Taking a guess, it may be simply that the 180s you installed were pulling too much juice from the resistors, which is why they popped. These ICs were used in many TVs, so it may be that the Panasonic doesn't have as much tolerance for the 180s' power requirements as, say a Hitachi.

Luckily, resistors are pretty cheap, so it's probably worth the few bucks to replace the resistors when you drop in the 110s you have in hand.

Burnt resistors


Depending on where you bought the ICs you could have fried the new ICs when powering it up with burnt resistors as the green is controled by both ICs one IC controling the horizontal green Convergence and the other IC controling the vertical green convergence. Have you checked all the convergence resistors out of circuit?

Stk392-110 chip replacement


stk392-110/150/180 all have same fit, form function except the 150's and 180's are basically upgrades for they're more stable (more heat tolerant than the original 110's); I'd buy the 150/180 myself; you can get the stk392-180 for just under 10 bucks on eletronix.com.
