Convergence IC CAn I swap a STK 392-040 for a STK 392-010?

Hi:
Your problem is the convergence circuit, you need to replace the convergence Ic's there are two large black IC's mounted on a large metal heatsink. The part numbers are STK-392-110 replace them with the same part number or use STK-392-120 for better and long lasting.

convergence ic stk----- you can repair this yourself if you can solder you can obtain ic.s from matt electronics or any electronic suppliers locate the convergence ic.s on chasis there will be 2 the number will start with stk- most likely stk-392-110 hope this helps

Just the name, Sanyo quit making the STK series several years ago Sanken, Toshiba and Mitsubishi all have good versions of the STK series.

Hi,
This problem is related to the convergence, but it requires replacement of IC STK from one of them who control convergence, check both and replace faulty IC STK from new one and your tv work fine again. You can buy the convergence IC's from the link click here.
Thanks for using fixya.

You need to replace the convergence IC, They start with STK make sdure you get original stk IC's and not cheap china made or aftermarket parts as they will not lasts long in your set. if you pay less then 15 bucks for your IC that really is no bargain cause it is most likely an aftermarket IC

Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

Thanks...

This unit does not use the STK series convergence amps.The convergence power supply is what you need.I will provide that number for you after while.

am having stk 4392 amp board 2 channel, i want to change this two channel in to one channel. what modofication should i do

Your message says you "replaced stk392-150", did you replace both of the stk`s or just one of them??? One is for RGB vertical the other is for RGB horizontal, you should always replace both stk`s as a set, Hitachi recommends you use a "replacement kit"
part number X480306", this kit includes both stk`s with a new & supposedly improved set of stk`s as well as all resistors that are required for proper set-up, they strongly recommend you change all of the parts in their kit. The only other thing besides IC`s & resistors that could cause your problem is:
1) bad dcu output (you need a scope to check this)
2) you`ve lost either the +15 volt line or the -15 volt line to the IC`s, "Fxxx" chemical fuse open in power supply.

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 ----/
