Just don't know with this one - Guess, shoddy ghosty 3D images,side way hour glass.

2004 or there abouts, Rear projection with the 3 picture tubes--16X9 HD ready.

Most common issue is convergence--see photos--if that with the Original remote go into the main menu and call up convergence--should display about 9 points on the screen with crosses---remote should (look at owner manual) allow you to try to adjust so you have yellow crosses with no red or blue or very little showing--if adjusts you are ok.

If will not adjust in some area up/down or left right the convergence circuit needs repair--should use two stk-392-040 or -020 chips--on this smaller set usually on a board inside above the main boards--

See if will adjust first (universal will not work for that) and let me know..



typical ic used, your will have a different stk number on it.

I have a samsung dlp ty model num hl56a650c1fxza whn I turn it on the tv tries to turn on but then it turn off and flashes green whr it says

First thing to do if DLP is remove and inspect the lamp--if shattered or the central glass pillar inside is warped it may be your problem.

In cases like this I try to see from openings near the lamp if it comes on for a moment and then goes off.

Also try to verify if the fans come on at all.

Lastly---if the set before failing was making a fan like or high pitched whine or even a grinding noise a color wheel is possible and common on this model.

You have a bad color wheel. The lamp may also need replaced depending on how old the set is and the number of hours. I have a tip at which will help you replace the light engine and give the best place to get a replacement. I also have a tip at which explains when you need to replace your lamp, why and where to get the best price.

Thanks for using FixYa and for the great rating.

I have a samsung sp42q2hl, which on the front of the tv say's it is a hdtv ready, and yet i cannot watch high defenition images or movies, also there is no hdmi inlet at the back so i'm not sure how you...

Use component to connect this will give yu HD picture,
On the back of the set you will see A group of 5 phono sockets Blue, Green, Red, These carry picture,

Then Red, White, these carry stereo sound.
Component video 0831d.gif
Component-video cable b.gif
Component video improves the picture quality even more by not only separating the color from the black-and-white portions of the picture but by further splitting the color information into two color-difference signals. When the picture signal is split up in this way, you get an unfiltered, uninterrupted image, with better resolution and greatly improved color saturation. And this is why component video is the predominant method of hookup from HDTV set-top decoders to HDTVs.

So this is how your set can produce HD picture from Hd source.
