Magnavox 19mf337b/27b flat panel tv doesn't boot up

Problem with Magnavox 19mf337b/27b flat panel tv. During startup, the picture gets static and the audio screaches. The tv then restarts. This happens repeatedly until the tv warms up and becomes stable. The situation has deteriorated until now the tv does not start up at all.

I had the same problem but was too cheap to replace the scaler board on a television which was not worth the cost. That board has 3 1000uf 10V aluminum electrolytic capacitors which had swelled tops and indications that they may have vented. Since they were installed using through-hole technology, they were easy to change with 1000uf 16V capacitors. (caps can not be more than 16mm tall). The set has worked fine for months. Cost of repair was 72 cents

I have a Magnavox 19MF337B, and it powers on and off a few times before staying on. After it powers on, I just get a white screen, and nothing else works. remote does nothing, and buttons on top do...


In some cases these TVs were to be returned for exchange. As costs were excessive. If this TV is out of warranty and you have no place to go with this TV, you might just have a hobbiest open the darn thing up. I would say you have a bad capacitor or two in the power supply. This is at its easiest repair. If not you may have a bad LCD panel and that is not worth replacing! Hope I could give a something to work with. Thanks for asking!

Magnavox 42 inch flat panel cannot get a picture


TV may need software upgrade. Go to menu, find instalation, find software upgrade, find. If version is bellow FL2D-r23 (#23) TV needs upgrade.
Get upgrade on the internet onto a USB flash drive. The file may be a ZIP file, if so, unzip to a folder in PC then put the file to the USB drive.
Turn TV on, plug in the USB drive, wait til the upgrade is finished. Unplug USB drive, turn TV off w/remote.
The TV will then turn on by its self and the upgrade is complete.
Hope this works

If the cost of repair is 50% or more of the price you purchase the TV at, your better off buying a new TV.
