Stk392-110 chip replacement

Hey TVtech guy

I have surfed the web and found an array of info on replacing the stk392-110 chips with the 150/180 series. I have a JVC AV-48WP74 - existing chips are the 110 series. What is the best choice for replacing chips - 110 or maybe the 150/180. Thank you for your input.

Use the STK180s they are the best the 110s do not hold up the leggs fall off after connducting to much heat.These ICs must be solder in see if you can find someone who can solder to remove old ICs and reinstall new ones you will also need white silicon heat sink to put on back of ICs as well.

Thank you very much. So sad hic hic. I'm going to try fixing it myself. I tried to find document saying about mainboard circuit but I found nothing. Do you have any suggestion? Best regards,


You won't find anything on the circuitry, not even from Dell. I was chatting with a tech Friend the other day on the same issue for a Dell machine. He had traced the chip down on the board and asked if I had one or could find one. After looking through all my resources and talking to a Dell tech that I use, found nothing. The Dell tech that I use couldn't find anything on the specific chip with his Dell resources and told me that motherboard replacement was the only option. Which I already knew. I've tried replacing the chip before with chips from dead parts boards that I have, and have only had about a 15% success rate. The chip replacement is a real nightmare, involves soldiering on the board under the chip. So, I'm sorry, but there's no info on this. I may be able to get you break down diagrams and instructions for your machine if you want to replace the board yourself. Let me know.

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.
