Remove the back containing the mirror and look into the projection lenses either at low brightness or with the tv turned off using a flashlight. Look for the fluid posibly being murky (should be clear). If this is the case, to replace the fluid: 1. Unplug the TV. 2. Remove the Picture Tube with Lens Assembly that has bad fluid 3. Find the drain plug 4. Drain the fluid in the sink. 5. Take a picture from all angles to review later. 6. Dissassemble the fluid chamber from the picture tube and clean the front glass and chamber. 7. Reassemble and fill chamber with mineral oil (laxitive found in a drug store). 8. Repeat the proceedure until all three CRT images are clear. 9. Use the centering magnets located above the CRT PCB's to get the convergence in the center. 10. Use the convergence proceedure from the tv menu to complete.

I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I replaced the missing silver box on the new board and I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce what are crt pcb's???????

There is a certain level of tolerance for misconvergence - it is extremely hard to get a set perfectly aligned. If you go into an electonics store you will often see the same thing - very slight misconvergence on small white text. You might could try getting the set re-aligned by a professional, or if its really bad you may need the convergence chips replaced, but it sounds like your set is normal.

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

SOURCE: Blue shadows on my tv was able to adjust the

If red adjusts but blue does not adjust in some direction one of the two STK-392-110 convergence chips is bad.

Both should be replaced at the same time (about 12 dollars on EBAY) AND THE set will also have a number of small resistors in front and around them (they are usually 1.8 ohm and should read like a fuse).

Repair involves getting the chips out and replacing them. They have 18 pins each and are soldered in.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

Look in main menu for convergence and see if it will adjust--if off either adjustments or a bad chip---picture will look 3d and red or blue outlines around lettering etc.

Xbox works fine but wont show up on the tv, sound is coming out but no video.

For, first time u should the following
play a movie using the Media Player for Xbox 360, a Windows firewall warning will appear
Note: This is due to the Xbox 360 playing the movies over the network.
Simply click the "Unblock" button on the window that appears (see below) and the
movie will play fine, i think so. You only have to cancel this warning once.

The console thinks the disk is a movie and displays play and pause and chinese looking letters appear on the screen. It won't allow me to do anything

The problem you are facing is of a copied Xbox 360 game you are probably trying to play on a Genuine Xbox 360, these discs are read as a movie disk and it shows as "Play DVD".

When you try to play such discs, it would give you dvd media control bar on the bottom and the message in chinese letters is actually a message asking you to insert this disc in a Xbox 360, which is actually a Modded Xbox 360 that is required

When I play Halo 3 it turns green. and other games get blurry in background, I just bought Fable 2 and I cant play that because it is too blurry, its not a scratched disc, and I rmoved dust in my 360

Hi,

you may have a faulty AV lead, from xbox to TV.
or the graphics chip is failing, if you have a composite lead ( red-white-yellow-green-blue ) check that the switch is set to hdmi correctly. this is on the side of the oval connector from xbox outlet to tv lead.
try tuning into a different tv channel, check that the lead isn,t broken internally.
If this does not work, assume that the GPU Or graphics chip has come loose, and obtain A RROD repair kit.

Mike @ Compurepair.

Xbox 360 wont play certain new release dvds.all else ok.whats up?

This is 99% always the case when your dvd drive is going out. You can find a replacement on ebay for under $15. Video tutorials can be found on youtube just by typing "xbox 360 laser replacement" Replace the laser and you won't have this problem anymore.

Samsung Rear Projection Problem (not convergence)

The tv has 2 focus adjustments for each tube, mechanical and electrical.

1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.

Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.

With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look

When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.

2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.

In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.

One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.

With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.

Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).

You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.

If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.

If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.
