Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Red Gun screwy!!

Two days ago, the red gun went whacky...I went into convergence and it went away. The TV ran fine for two days but today, I turned it on and the same thing it happening. The red is about 2 inches too high on the left side and sweeps down to about two inches too low on the right side. ALso, the top right is too high, but the center looks fine. Can anyone give me some direction at to where to begin troubleshooting this set? Thanks!

Re: Red Gun screwy!!

You have a typical convergence problem here that happens on just about every tube type projection TV set ever made. There are two STK IC's that will need to be changed. Best thing to do, if you have any soldering experience on printed circuit boards, would be to get the service manual, locate the convergence amp IC's order the correct parts and not any replacement IC's that cost less the 20 bucks, and change the IC's. If you have no solid state repair experience, play it safe and call in a pro to assist you in this repair. Good Luck

Sp43w6hp red gun convergence problem

as i see in your comment.. you have defective convergence correction amplifier ICs. the RED GREEN and BLUE (RGB) is amplified by the STK ICs. your RED convergence is not working good in the STK ICs! Replace the STK ICs a new one to get back the normal colors. Thanks...

I just moved my 42in. Toshiba rear projectiom Tv from my basement to the upstairs and now my convergence is off. The red tube cross is low on the manual adjustment and will not go up to the other colors.IT...

It sounds like you jostled the red CRT gun when you moved the set. If the convergence adjustment still moves the red cross hair the the circuitry is okay. Your red gun needs to be realigned. This requires a service call unless you want to attempt it yourself. It is fairly involved and requires some specific tools as well as using the service mode on the remote to reset the convergence after the gun is repositioned.

Red convergence problem - Mitsubishi 65

It sounds like your red gun might be close to going, we had the same problem our tv. The red was off and couldnt really be adjusted but the others were alright. We were told that the red gun was nearing the end of its life and it could cost upwards of $1000 to fix, so we just got a new tv. i would suggest having a tv tech come out and look just to make sure, but thats wut it sounds like.

Blue Projection Gun

It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

Hitachi 50UX14B rear projection: Took apart 2 clean, now red is off

What do you mean by covers? do you mean focual lens? did you replace them to there proper place (red to red, green to green, ect..). each has it's own focal legnth and must be placed on the correct gun. did you adjust (accidentaly) the red centering polls?if you did please have a tech readjust them you can end up with convergance amp overload. did you try to converge the lines? if they did not move when adjusting you may have a convergance amp problem. read my motto
