I have a Magnavox 37mf337b/37 tv that wont power on. I need the part name and number for diodes zd906 and D924 that are located under the transformer.

SOURCE: Red bar across top of screen??

I had the same horizontal, solid red bar along the top of the tv screen. I have an older analog Philips Magnavox TP2785C221. It just started all of a sudden. It was on every channel. However, the bar did not appear on the other input channels (e.g., AV1, AV2). So this meant that the red bar was only occurring on the antenna input. I unplugged my cable decoder box and restarted it. The red bar went away and that seemed to solve the problem for now.

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.
