What is it exactly that you have to adjust that you need to get into the Factory Service Menu that you can NOT adjust in the "customer" menu ????...
That info in the wrong hands can & often does create havoc with the TV's functionality....

There is no "customer menu" option on this television. The convergence chips went out and my brother thought he would go into the service menu and look for a convergence option there and he changed alot of settings. Now it has the convergence issue and a concave curve to the screen. And other various issues with the screen. He said on one of the screens he found the 3 cross's that you can line up to solve the convergence issue, but whatever he did didnt work !

Let me back up here, when I first got the television it did have the menu to align the colors but now that menu does not show up in the options under the menu settings ??

elkcitian;.....

Your brother needs a knuckle re-alignment , if you get my drift !!!...
I have a PTK195P4A & a CTC195 service manual.....
The CTC is for direct view...
The PTK is for model # 46GW948YX10 & it's a Sams Photofact Folder....
Look familiar ????
In neither one is there a feature that would restore convergence proceedures...
There are adjustments for:...
Horizontal Size EW DC
Pincushoin Amplitude
Pincushion Tilt
Top Corner Pin Correction
Bottom Corner Pin Correction
Vertical centering
& Vertical Size or Height

I don't see how ANY of those adjustments would do you any good....
NONE of them would bring up "crosses" on-screen...

If you like I can email you either one or both manuals if you PM me with your email address....

That would be great. Thank you and believe me I put my left foot in and then took my left foot out and then put my left foot in again and shook it all about, and I was not doing the hokey-pokey ! lol He was trying to help and looked like he knew what he was doing when bringing up the "secret menu" so I let him run with it. Now I just want to get it back to the way it was and then deal with the convergence chip issue. Its an older television but it has had a perfect screen up until this recent issue and I think I can replace the chips without really damaging much more. If not, well it was a good run ! thanks again

Sorry about the delay , but , for some reason , I could not upload the manuals to email them last night....
Found out why this morning....

Reason is , that the "CTC195" service manual is 29 MBs...
Netzero only allows me to attach files etc up to 20 MBs...
So I sent what I could....

The CTC manual has NO schematics....
IF you want it , let me know & I 'll see if I can find a way around that hurdle....

Before you do the herky-jerky (Formerly the hokey-pokey) , or cartwheels , I seriously doubt you are going to solve your problem with this manual........
I see NOTHING in there that is a "Magic Bullet"........

You might consider calling GE (RCA) & asking them for help....

I still think that you are going to find the convergence adjustments (With the crosses) hidden somewhere in the customer menu....

Let us know how you make out with this info.......

GOOD LUCK......

I will be posting some of this to your thread for the benefit of the readers....
EDIT: Posted ALL of it.....

PLEASE destroy (delete) my email & address after you download the manual....
Thank you....

PS;...Just noticed that I sent the wrong manual....
Will resend with the right one soon.....SORRY....
EDIT;...Sent....Check your inbox....

Later....Ron.M..... Cool

BTW;....
This set does NOT have the usual STK series convergence ICs....
There is another problem that causes your convergence to go whacko.....
It is a power supply problem....

Hey thanks for the manuals. I opened the back and found that it does have 1 stk730-130 chip. Will replacing this 1 chip fix my convergence problem ? I took a picture of the chip if you need to see it, thanks again
Looks like I can replace the stk chip and then probably replace the pico fuses and resistors pretty easily on the convergence power supply board ? I found a stk chip for 3.99 online with a 6 month warranty and radio shack carries the fuses so who knows !

Lol...I laugh when all "veteran" posters want to do is chastise new members for not searching the forums (not necessarily this one in particular) when they ask for help. While in some cases posters ARE just being lazy, in this case, I am NOT ! After searching EVERY post on this forum for problems concerning my model of television, I asked a question not found on here and RON was good enough to reply. And in our limited back and forth replies, he stated their were no stk chips for my model, and when I took the back off I found one, so I was asking if this chip were to be replaced and then the other circuits on the board were replaced, if this would solve my issue. So what more homework should I have done or still need to do ? Maybe you could direct me to the post that I have missed that applies to my question and I might owe you an apology ! lol

Re: [elkcitian] GE 46gw948 settings [In reply to]	Can't Post

And the reason I am asking the questions in the first place is this thread [http://www.tv-forums.com/cgi-bin/gforum.cgi?post=11415;search_string=46GW948;#11415] suggests a place to buy the board it looks like I am needing. But when you add the part to your cart you will see that it says its a non stocked part and that their is a 20.00 core price. So it leads me to believe that its just like buying a starter for a vehicle. You basically trade in your defective part for a new one and then they "repair" your old one and then re-sell it to the next individual. So what I was asking was if I could basically do the same thing to my board, replace all the fuses and circuits on mine and save myself some $$$. Seems to me thats all they would do, but since I am not a repair professional thats why I was asking. And I am not trying to be a jerk, if thats how my last 2 posts are coming across ! lol

Will replacing this 1 chip fix my convergence problem ?

Usually , it does....IF that power supply is not putting out any voltages....
One way to find out is to check the IC pin (U19700) voltages...
If they are not close to what is on the schematic , chances are that the IC is bad....
Notice that the voltages are read in respect to HOT AC ground & NOT chassis (Usually tuner ground)....
$3.99 seems dirt cheap for that type IC....
I have NO clue as to what fuses & resistors you are talking about....

GOOD LUCK..... Sly

Keep us posted on your results....OK....THANKS....

Re: [Ron.M] GE 46gw948 settings [In reply to]	Can't Post

Wasnt refering to any specific fuse, was just saying that it didnt look to difficult to replace the fuses since there werent too many of them. Would be kinda like rebuilding the board by replacing them. I dont know, but since the stk is less than 5 bucks and the fuses are .39 cents at radio shack, figured might be a 10.00 fix and if it didnt work, well I definitely got my moneys worth for the tv ! lol Replacing the board is 150.90 plus 20.00 "core" charge so I think its worth the 10.00 to try ! Thanks again

We need to clear something up here....

he stated their were no stk chips for my model, and when I took the back off I found one,

NOT quite..

This is what I said;=>...

Quote

This set does NOT have the usual STK series convergence ICs....

NOTICE that I said "Usual STK series CONVERGENCE ICs"...
The IC you refference (STK730-130) is a "Power Supply" REGULATOR IC & NOT a convergence IC....
HUGE difference...
I stand by what I said.....

Quote

then the other circuits on the board were replaced,

There are NO other circuits on that board to be replaced....

IF you had read & absorbed this from your link;=>...

Quote

if the power supply for the convergance board fails you get a real crapy mis-converged pix and some times the main micro no longer sees the convergance board and deleates the convergance adjustment from the main menu, this sounds like what has happened here.

BTW:...When you fix (?) the power supply , the convergence adjustments should show up back in the customer menu....

Good Luck..... Sly

search: PTK195 + convergence

Many models use SAME "basic" chassis. Smile

EDIT:
search: 46gw948 + convergence ... equals two threads (including this one).
search: PTK195 + convergence ... equals one and a half pages (34).

Ok AND ?? I searched and read every thread containing 46gw948 and then asked my questions. Why would I search PTK195 when I had no idea thats what my chassis model was until Ron helped me out and gave me all the answers and a manual I needed. But thanks for the lessons in search Etiquette, helped out alot ! lol

ALL one of them? (Plus this one)

Reread YOUR 1ST POST - Model number, chassis number and convergence are all contained there. Angelic

Yes as I was the one POSTING it ! I only found my chassis number AFTER searching this forum but wanted to make sure I was right BEFORE going any further. Seems like all you want to do is argue ?? Am I getting that right ? But by all means reply AGAIN with a helpful comment concerning my television problem. thanks
