Re: Magnavox Model 37MF231D/37 dead
I've been trying to figure out the manual which contains info for 26", 32",37", and 42". It seems to apply mainly to the 26" with reference to other models. It does contain a 37" and 42" supplemental material for the P/S. Using the P/S info and probing the board I found that on the
1089 connector to the Main Board:
pin 1and 2, 16v is reading 11v
pin 3, 24A is 24v
pin 4, Bright adjust is 0.788v

Magnavox Model 37MF231D/37 dead
This TV is dead. After reading some of the technical material on this forum I measured all the pins on the IR/on-off board and there is no voltage present on any of the pins. My understanding is that there should be a %VDC standby voltage here that is used to initiate the other TV functions at turn-on.
I got this TV from my brother-in-law who said it just stopped working and he was going to throw it away. So I am using it as a learning opportunity and trying not to use it for target practice.
I inspected the p/s components and found nothing obvious; no burned parts,... -

Re: New Members - please post your introductions here
Howdy,
I've been around electronics for a number of years. Worked mainly on Airborne Radar while in the Air Force (4 years) and as a civilian with the Air Force (25 years). I have a multimeter (Fluke 75) and can follow schematic but no LCD or modern TV experience.
I currently have a Magnavox 37MF231D/37 that does absolutley nothing. I got it from my brother-in-law to see if I can fix it. He was about to e-waste it so I thought "what do I have to lose". This forum looks to be full of helpful people...Leave a comment:
