Question about SNK Magnavox 19MF338B/27 19 in. LCD TV

2 Answers

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 nothing. No sound either. I have tried hooking up to TV cable, and Monitor cable, neither which work... Debating after reading some other posts, if it is even worth fixing. Anything for a neophyte to try as far as a fix?

Don't buy anything from Magnavox or Phillips period. They won't take responsibility for their products and have no ideas what customer service means.

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!

    I will never buy Magnavox again. When my father called Target, they were rude and told him to call Magnavox. When he did, they blamed the issue on him. We only found out about the faulty components by searching on line. Neither company has no idea of what customer service is and can bite me.

SOURCE: My magnavox 42mf438b lcd tv will be fine for about

that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

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


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

Magnavox 19" TV shuts itself off.....won't stay on


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps
