Convergence problem Toshiba tn61x81

How do I adjust the convergence in this set? I can get to service mode, but I cant get into any adjustment menus. Is this something I can do myself? I'm a little technologically inclined, but know very little about tv's. I am pretty sure this is the problem as I have a 3-d type look to the screen which suddenly happened tonight. Argh! I have already spent 300+ on servicing the integrated circuit, on a $500 used projection TV. How much $$ am I looking at, and is it worth it? Thanks!

Re: convergence problem Toshiba tn61x81

You need the original remote control to adjust the convergence..If you tried the original remote,and still have that problem,I would advise you not to spend another dime on it...You can shop around and buy a new big screen tv with 3-5 year warranty,and less headaches..Check vance Baldwin electronics in Georgia to see if they can order a remote for you..Good luck..

Tried to auto adjust the guns, will not come within range

Hi Tod,

If colors do not align correctly, most likely you have a convergence failure. This requires replacement of the 2 STK ICs and possibly some low ohm resistors.

Some Toshiba have a Horizontal oscillator/Drive IC failure that results in a small or shrunk picture (2-3" border on all sides). The 3 colors do not align properly because of the reduced Hor drive signal. The convergence adjust controls will work but not allow good adjustment. Convergence is ok, Hor Drive signal is incorrect.

Many do-it-yourselfers mistake the Hor Drive problem in Toshiba RPTV with convergence failure. Too much adjustment of the convergence controls may cause the saved data to be really messed up and require more difficult alignment in the service mode.

If minor or simple adjustments in the customer convergence adjust menu do not fix your problem, there is a fault. Stop adjusting until fault is repaired

Convergence failure can be accurately identified with the Convergence Gallery on our website. Service in Toronto, Ottawa, Calgary, Edmonton and other Canada cities.

Toshiba TN61x81-- after convergence IC's replced

Please don't be offended by my suggestions if you are experienced at circuit repair.
You may have a cold solder joint or bridged joint. Check and re-check your connectors for placement. It is normal to have to adjust the convergence and focus after replacing the IC's. There should be a row of focus knobs (ususally covered by a piece of black tape) with the screen controls.
The convergence IC's won't affect the visibility of a color only the alignment.

I cannot adjust the convergence.

You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.
