Question about Toshiba 46XV640U 46 in TV
Guys I found it. It is on main board on Toshiba 46xv640u TV.
You need to know how to solder very small parts, or ask someone with steady good hands to help you. It is faulty 22uf16v capacitor. It is marked on the circuit board as "C606". It is somewhat between two big heat sinks (cages). Do not try to solder out bad cap, nearly impossible. Just twist it off like chicken head, and then using soldering iron just clean soldering spots. You don't have to use SMD Cap. Just band the legs of regular one and solder, watch polarity of course. I am pretty sure this one causes the problem with delayed pictures and no picture at all. I have spent weeks every day to hunt it down. I am not a professional but very stubborn. I even bout ESR Cap meter for this project. Have replaced dozen suspitious CAPs with no success.
So Guys save money. Try it before buying new main board or new TV.
Fix it and be proud of yourself, and give thanks to God because God Is Good.
If someone will have success because of this info, could you please comment. I would be pleased to know my solution helped someone.
