Press menu button on the TV if the on screen display is also distorted or no pic the TV is definetely defective. You can try unpluuging from wall for about 15 minutes and see if reset helps if not problem is either main p.c.b , LCD panel , LVDS cable or Power supply board. and would require service. most likely problem would be bad connection at or defective LVDS cable that connects main p.c.b to Panel (cheapest fix) or defective main p.c.b. If it is the panel it would probably not be worth repairing and you may want to sell as is on ebay.

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.

Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.

Magnavox turns on then goes off model 37f337b/37f437b

More than likely power board,usually repairable,look for blown capacitors.A blown capacitor will look like the top is rounded also suspect capacitors will show signs of the plastic coating shrinking .
