Question about Jwin JV-DTV27 27 in. HDTV-Ready LCD Television

Open Question

Color problem A couple years back I bought a jWin JV-DTV27 Lcd "hdtv ready" tv set. Somewhere about one year ago it started showing a erratic color problem: The light color areas of a scene display red bands, of moderate intensity. The bands are about 2mm wide and separated another 2mm between them. In the darker areas, the bands are still present, but very faint. The bands have a "noisy" texture, they are not solid. If I switch channels or do anything that bring on screen a popup window (like changing the aspect ratio, or volume, whatever), the screen gets crossed by thin vertical red lines, about 20 of them, separated about 20mm each, and leaving about 50 mm clear at both sides and about 25mm clear above and below. These thin lines stay for as long the popup overlay stays on screen. The most weird thing is that the problem appears and goes without any other consequence. It may last for a few minutes or for hours, or disappear for months. Humid days seem to me to be more likely for the lines to appear. I brought the TV set from USA to Argentina, can not get it back for repairs. No knowledgeable official service here, not on warranty period either. When the problem appears I just switch to a low intensity color profile and the TV is still viewable, but somehow, even when no one else complains at home, the faint lines still hurt my eyes. Could someone please explain what the problem is, and how to fix it ? Thanks

This sounds like micro glitch try unpluging the tv and all controlable inputs (PC, iLinks, or other such devices) wait 5 min then plug the tv only in and see if you have returned functions. if you should read the manuals of those devices to see if the control functions can be turned off.

I am sure there is one to download. If google is no help, just ask some deep web specialists, e.g. - this is a manual search agency and if they don´t find it, it does not exist in the Internet.

I bought this tv, more or less 4 years ago, and I'm live in brazil. So, when I got here the Tv was black and white, no color! What's wrong? Can we help me?

Depending on where the set was purchased (USA) it may be NTSC format and Brazil is likely to be different format like PAL or even Seacam---they do make converter boxes that will convert signal from one format to another.

I have a KP-51ws520 that a friend gave up on and bought a new LCD TV. About a year ago, after a power outage in our neighborhood, this tv now has noticeable streaks across the screen at all times. Is...

It depends on what the problem actually is; are the streaks colors like red or blue outlines around lettering etc?

The more you tell me the better I can help. I will post a photo or two of what convergence problems look like.
This set is also prone to another problem, on a blank video input look at the screen: you should only see Video 1 (etc) and if you see faint curved lines (red, green or blue) and or the back ground is also wrong color you have the second problem.

let me know which it is.. If this information helped you rate this solution as very helpful as I do this here for free.

Image Color

Hi,If there's any discoloration,pixilation or hues on the tv it will be an issue w the light engine's 3 lcd chips.This link explains how the lcd technology works: Basically there's 3 LCD chips that create the colors and picture by blending together all when the light of the lamp goes through them.When they start to melt they will start to show the symptoms.You will need to replace the 3 lcd chips or replace the light engine.Good luck and God bless your house!

Im getting a whirring noise in the back of the tv but the picture and sound is still on. picture quality is still good. i dont know if its the fan. color wheel was replaced a year ago. but the tv stopped...

Well that whirring noise is most probable to be the color wheel. Funny thing you replaced it a year ago. But it's most probable that is the issue. You did get the right one, did you? Because with Samsung TVs they have 2 types of color wheels, either gold or silver bearing.

Screen shows only black and white

Color wheels do go bad quite frequently, if you got 5 years out of the original, believe me, that's good.
The color wheel is attached be a bearing, like a fan and when the bearing starts to ware out the color wheel on the shaft starts to wobble and that's what you hear, they spin I believe around 3000rpm. Try contacting your servicer again, don't be mad, maybe he'll be kind enough just to charge you for the color wheel. I'm sorry, but that's the best advice I can give you..Good Luck...
