Question about Televison & Video
Is it possible to adjust the convergence without the remote for the TV? I was given the tv by a friend and it came with no remote. the picture is blurry and the color alignment is slightly off. I am trying to adjust the convergence but all I have is my comcast remote and the buttons on the front of the TV. I get stuck at the phase of adjusting the red in the 9 different positions because I dont have a # button to swith positions.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The tube should be ok its the IC's regulating the convergence is your problem . A tv repairman should be able to repair it fro around $250.00 - $300.00 or less depending on who you call. Good luck

You dont need codes for the service menu you need to repair the convergence circuit. If the lines wont line up in the customer menu they wont line up in the service menu either. Do you know how to solder? If so we can fix this yourself with a little instruction. Otherwise you will need to call a repairman. A good repairman will run you $300-$500 depending on your area. Let me know what you want to do.

Though i answered this exact question tonight, but maby it didnt post, sorry...heres the instructions.
To enter the service menu follow the directions below:
1) Go into the menu and select cable mode
2) Set sleep timer to 30
3) Exit menu and change chanel to 124
4) press and hold volume down button ON THE FRONT OF THE TV
5) A red "chk" should appear in the top right coner
Once you have the red CHK i think you press action to get the menu up, then chose convergence.
RTUNE- changes colors
MUTE-makes the cursor blink and not blink (when its blinking you can move it from point to point, when it stops blinking you can adjust that point)
"7" - saves the changes you have made
When you are done to exit the service menu follow the directions below:
Press ACTION and POWER buttons together on the FRONT of the set
the tv should the reset itself and turn itself off and back on.
Also if you have a convergence problem and have not repaired the circuit then going into this menu and trying to do adjustments can cause major problems in the dcu so if you have not repaired the circuit DO NOT go into this mode. you must first fix the circuit, and if you dont know how to fix it then you should call a repair man. You can cause major problems in the menu that are not fixable once they have been done.
Let me know if you need more info!

Testimonial: "SD TECH, thanks for you expert advice! This is a great service and you saved me a bundle."
What you might be experiencing based on your symptom sounds like a damaged convergence IC.
If you cannot move the colors with the convergence menu then you have a damaged convergence IC.
With any Projection Television that has a damaged convergence IC, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.
With that aside I have some support suggestions that I have put together that may help you make an informed decision.
You should be able to get a local service center to repair this at your house for between $350.00 - $450.00.
If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.
When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.
There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.
Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.
I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.
You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.
I hope this information allows you to resolve this issue.
If I have helped you, please help me, and rate this suggestion the highest FixYa rating. (Two Thumbs Up)

Thanks for using FixYa
I have attached some photos of really bad convergence problems, your picture may not be exactly as bad as these, but here is something to compare your set with.
