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?

Bowed screen after replacing ic chips and resistors on a 57F500A

The 150 never seem to fail, either new chip bad, you missed a bad resistor, something during soldering bridged or shorted, worst possible reason would be the DCU is bad and it is the least likely.

98%of the time in this situation you either missed a bad part, installed a bad part, or created a problem with the soldering or removal of parts.

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.

Power Light blinking 5 times

check the resistors near the
stk's. There are some reports that they get fried when the stk's fry....or the other way around. The resistor ratings are labeled on the resistors. 2.2, 82, 180 or something like that. Also check the board as you turn on the tv. See if any glow red.

Re:hello again

resistor replacement is very easy compared to IC replacement. You have to unsolder one side of the resitor and lift that side out of circuit in order to test it properly and if it doesnt measure its open and will need to be replaced or if it reads more thatn 5% of the rated resistance it will also have to be removed as the resistors are all 5% tolerance or less in convergence circuits

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?

if you can remove the rear panel assy. look for the convergence ic's they start with stk--- and you got the part number you need a source panasonic is 814 source and the number on the ic's stk 390 ----/
