Re: magnavox 19mf337b lcd tv

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

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 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

Your not alone with this problem.
I had to fix mine. The warranty is less than impressive.
The trouble is going to be the Power Supply/Backlight Inverter board.
This is the picture of yours:

Fixing the board like I did seem to be the only option. If you need info on fixing it, let me know.

Vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

White lines equally spaced 1" apart.

This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.

Dark vertical lines on tv screen

If under warranty then of course use that.
This is a display problem. One solution someone knowledgeable in electronics can try.
This problem can be caused by a bad connection fitting of the flat cables on LCD controller board. Dis-connect the flat cables from the LCD controller(T-CON) and carefully reconnect them. Try the unit before reassembling the back cover. You may have to disconnect/reconnect several times to show improvements if this is the problem.
