I'm going to chronicle repairing my 32" Sony HDTV. It's model number
KV-32HS420. The television starts up but goes into standby mode before a
picture comes up. Watching the standby light, I noticedthat after it
shuts off, the led blinks 7 times. This lead me to search for the
symptom online.
I googled so many search terms trying to find a complete answer but was unable to find an easy answer to my dilemma. I finally found a Sony tech manual at a resale shop. The manual called to replace IC8002 and IC6501. My electronics background let me know that I was searching for an Integrated Circuit or chip. So I removed the back panel from the TV and began looking for IC's. There are only two on the main board and both chips were the exact same type of chip, (MCZ300-1DB) I haven't removed the board yet but I've found what needs replaced! Troubleshooting this has been a breeze so far.
Now I'm ordering the chips. I found them here. $14.99 with free shipping. DEAL!! As soon as the chips arrive, I'll pull the board out and solder in the sockets and new chips.
NOTE: After finding my solution on my own, I found a walk-through to fix the very same TV. It seems that I'm on the right track.
I desoldered the two IC's and replaced them with sockets in case I need to change the IC's again. The hardest part was getting the post office to deliver the dang parts.
SUCCESS!!
Working like a charm again for $15 in parts.
