Magnavox 19mf337b 5 months various problems power off, ghosting, alarm noise

I purchased the LCD TV in 02/2008, started powering off and back on, various color ghosting, alarm noise, clicking noise right after power on. After warm up for 15 to 30 minutes seems to work with some ghosting. After 5 months Magnavox wants $300 to mechanically replace a TV that original cost $399. Purchased from Best Buy and they want me to pay for labor to have Magnavox repair and TV gone for at least two weeks. I do not like either option. Any other suggestions? I am not sure why Best Buy or Magnavox will not standy by the manufacture or sale of the product. BBuy wanted $100 for service policy when the TV was purchased. That really seemed like a good thing to not do at the time. I have the same exact problem you are my 19mf337b is only 9 months old.

    I have the same problem. Powers on and off multiple times with loud squealing noise that drives me through the roof. Have not yet taken it to tv repair shop. Based on what I am reading it is not worth repairing. Better to throw it in the garbage can. TV also came from BestBuy.

    thought i was the only one...problems didn't arise until i installed windows 7 and got the latest nvidia driver, instantly upon installation these problems began, what a shame this was one of my favorite tv's i have ever owned.

    I have had this monitor about 6 months. Intermittent wild problems with audio and video, seems to get better after about one hour?

    This sucks!!!

    Welcome to the new world of Chinese products, The Chinese don't care about quaity, they care only about something they never had before... money.

    I remember when a TV would last 20 years. I'm dating myself. Magnavox used to be a greta name.

    Buy Sony

I am currently working on this model set and have discovered the same type of problems. Fix: 4 capacitors in the power supply section on the main board were defective (bulging out). Common problem with counterfeit parts that originate in China. See http://www.badcaps.net for details.

---Copied from JustAnswer.com---
The noise you are hearing is the power supply. The safety circuitry in the TV is shutting it down when it detects a problem. This model TV is known for having issues with the power supply. Normally this repair will be in the $250 price range but can depend on what other parts are found to be defective. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair the tv must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

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/27 will turn off and back on with loud noise through the speakers until it warms up. approx 30 to 40 min. What is the part causing this common problem?


Check the 2200uF capacitors for bulging. You can get the schematic here to really toybleshoot: http://www.electronica-pt.com/index.php/component/option,com_remository/Itemid,34/func,download/id,15048/chk,6022df47696641c1c064cb27f2bd7d11/no_html,1/

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

XBR 4 vertical black band, ghosting/smearing, getting worse.


Hi, I have a similar issue which is progressively getting worse. My TV is on a sliding mount, and interestingly enough, sometimes I can "jilt" it by hitting it and it clears. This seems to me to be a connector problem, where heat (thermal expansions, electrical resistances) can introduce degrading signal. Now if I could find a manual on how to take this damn thing apart.......Certainly does't solve the warranty issue, but at least gives a reason for one to kick their TV.
