This is a convergence problem that will require factory service. Convergence adjustments must be made with particular test images and tools to access the internal adjustments. This is not a DIY repair.

The solution is an easy fix. Ignore anyone telling you to take it to a service center or to replace the convergence driver. You need to access the service menu on your television by using your remote control:

DRIVE CONVERGENCE Adjustment (Using remote control)

•Use the inner RGB box pattern.

(1)Set the [SLEEP TIMER] key to 0 min.

(2)Press the [DISPLAY] key and the [VIDEO STATUS]key simultaneously.

(3)Press the [9] key to display the RGB box pattern.

(4)Select the R mode by pressing the [DISPLAY] key.

(5)Adjust the R mode to setting as same as G mode bypressing the [CH ]+ / [CH -] key.

(6)Select the B mode pressing by the [DISPLAY] key.

(7)Adjust the B mode to setting as same as G mode bypressing the [VOL] - / [VOL +] key.

(8)Check to see that the cross pattern is white. If thecross pattern is not white, readjust (5) to (6).

That's it, your color is now corrected. Yes, I know...your welcome.

I pressed rgb on the remote-now i cant get out of that mode


Have you tried changing the TV to another input? Try Press "TV" at the top then press "TV" near the bottom or try pressing the "INPUT" button on the TV itself until you get to TV. RGB is just another input for the TV, just like DVD or HDMI or VCR, but it is the plug in the back for a computer monitor. Yes, if you'd like to hook up your computer to your TV you can through this plug, it looks like a (most likely blue) with 3 rows of holes/pins that you can plug another RGB cable into your computer and have the biggest computer monitor on the block! haha Although, if you have a PLASMA TV (not LCD) you can't use a computer for long (no more than 15 mins) because PLASMA TV's have a tendancy to "burn-in" very easy and it is sometimes not fixable. You'll have a ghost image of any stationary image that is on the screen for too long. That goes the same for any news channels with a "ticker tape" near the outside edge that is on the screen the whole time. If you have LCD, no worries! They're designed just for that problem to never happen. Hope this helps.

First of all sorry for delay.

If it is ghost image we can try by entering SERVICE Menu and adjust RGB level of the light engine.

Good luck

Ghosting and popping noises


slag, Has the cable signal been branched off to another TV (or more) from the same feed? Ghosting and shadows are usually the result of bad impedance matches on those lines. Try connecting the prime TV directly to the cable box (or cable jack) output and note if there is any improvement. Make sure the cable itself is of the RG-6 type (not RG-59) and has no sharp bends or kinks. The center pin of the cable should be clean without corrosion. The RF IN jack on the TV should be checked to make sure the threads for the connector are clean and the plug should be attached firmly but not too tight. These steps should help solve this at least assuming the cable signal is good. [Checking it shows the "level" coming off the pole, not necessarily the quality of that level.] Hope this helps.
