Location of inverter board on sanyo dp42841 - Sanyo 42 in. LCD TV

Hello davidweldon,

If the inverter board is bad, I would suggest that you replace the whole board unless you have a SMD (Surface Mounted Device) rework station, and a background in electronics. I have worked on TVs where people have tried to remove SMDs and it never is an easy thing to do, so I would again suggest that you replace the whole board, because all of the components are SMDs.

Now as to your question, I have seen on these sets the majority of the time it is a driver transistor that goes bad.

I hope this helps,

Thank you,

determine first if with sound off you have the problem---if not it is audio related and if with sound off it is still there it is inside the set....

Try unplugging it. That is usually the reset.
