I have a Durabrand 19" tv. It is less than six months old. when you first turn on the set, it is fine. But, after about 5-10 minutes, the screen goes fuzzy and white. You can still see the picture, and the sound is fine, but there is a kind of glow in the image.

Re: White blurry screen
Your Having a Problem with the High Voltage Transformer in the Set,You can pull the Back off(Not Advised)And you will find two controls on the Flyback*The Flyback is the Unit that has a Red Wire coming out of it Going to the Top of the picture Tube,with the set on adjust the One contol that says Screen,Till the Picture is Normal....Good Luck

you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again
If the set has contrast and brightness controls, try them but this problem is normally caused by a certain capacitor (I don't know the circuit reference number for this one) failing and it will continue to decay.
Any competent TV tech (if you can still find one) will know where to look.
Hi. Thanks for writing this posting. Saturday, my 19" Durabrand tv literally stopped working. Before it shut down, I had a partial screen and when I turned the tv off (hoping that the problem would somehow rectify itself), it wouldn't turn back on. I had it for only *four* months. Comcast gave me an 800 number but it rang to a fax signal. When I saw the posting here, I clicked on the Lenoxx site and called their 800 number which did not even ring. I called information and received a number, 877-874-8394 for Lenoxx Manufacturing but the person who answered said that they are Plaza Wire Design with Lenoxx being one division - but they manufacture towel racks. Ugh!
Unfortunately, this all happened one month after the 90 day return policy at Walmart *and* they don't even carry the product anymore. (I don't know whether it is because of defects or turning over to LCD.) One year prior to this, I purchased a cd/radio which also stopped working (the cd player). Luckily, it *was* within the 90 days of purchase and I returned it. They stopped selling that product as well.
Here is a possible repair for your problem. Remember that this is not deffinet.
This does sound like a difficult problem, it might be better to let a repair shop handel it.
Poor contrast and picture disappears in Vivid and Pro screen modes. Problem was resolved by replacing C210. The capacitor was breaking down under operation. Important note: capacitors C257 and C248 are in parallel with C210 and similar failure of any one of these three capacitors could cause an identical symptom. C210 P/N 112776011
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
Yes there is, a solution. There is a vertical sweep issue with your TV set. It could be a vertical output IC and or the sweep power supply feeding the IC. This repair will involve trouble shooting the vertical circuit, and replacing parts. If you have no solid state repair experience, my best advice would be to take the set into a repair shop and get an estimate on this TV. The repair, in most cases, should not exceed 125 bucks, and thats a high end cost. Good Luck
You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.
ok your problem is the RGB section maybe crack soldered at the RGB try to resoldered it! you seen that at the back of the picture tube they have small board attach at the neck... resoldred all small part, and transistor drivers!!!
Sounds like theres a leaky capacitor in the screen drive circuit. I have seen this problem also be a gassy crt but was able to clean off the grids of the CRT with a crt/rejuvinator. It happens because of low emmissions in the tube and when white is on thats a mix of all the colors, so the tube works harder. I bet when you whatch a movie and the scene changes suddenly to a white or brite scene the pic looks a little washed out. If this is not the case then I aggree with the Pravin and try it on another TV just to be sure .. This is not a repair for a consumer to do, though however it is only a three year old set you stated, so there should be life left in the tube, so im kinda thinking a capacitor is bad. Seek out a yechnician to check this out for you as a TV is not a place to see it you can fix it or to exoeeriment with. Good Luck
