Can anyone help with this scheme as it is not in eservice archives.

The reason being I need the value of the inductor that comes off pin5 of the LA78040 vrt ic. It's burnt beyond recognition. Hope the vrt ic is'nt fried. Crying or Very sad

Cheers if you can help,

SCR.

I have a Teac Color TV with exactly same problem. The small inductor was o/c but not completely burned up! From the colour bands it looks like 27 uH
I substituted a 33 uH of a larger physical size, boxed up the set and it seems to work just fine. Maybe its a weak point in this model. I post this info for anyone stumbling along the same troubleshooting path !!!!! Cheers

Is this the CT-F5170 model and the inductor is the L401? I have that same problem and I don't now the inductor value.
Thanks

Hi,
The above message is mine. I didn’t read the subject as I read it after a search. I do know the problem is from the same TV.
A fellow wrote me this about the same problem, I don’t know if it’s for the same TEAC TV. “I have just talked to Frank, our TV main technician. He has seen a fault like this on this TV before, and recommends replacing the inductor with a 1ohm fusible resistor.”
Cheers
