Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Green out of convergence

One day, for no apparent reason, my green was way out of convergence. After much research I learned how to get into service mode. Red and blue are perfect, but the green is way off mostly on the bottom half of the screen. When i try to adjust the green, it will go so far and then seem's to pop way out of alignment. It then adjusts rapidly back down but seems to stop after going so far. Any suggestions?

Re: green out of convergence

The green convergence IC is defective. this is not a job for the consumer to do as it requires the experience of soldering and unsoldering and the know how and the safty nissues concerning the HI voltage inside these sets. Please consult a pro to assit you in this matter. Good Luck

KP-61HS30 Sony TV turn pink and green text is bowed


Check out CONVERGENCE GALLERY . If you see your symptoms you have a problem in your convergence amplifier circuits. Typical Sony Convergence repair requires disassembly for replacement of 2 ICs, sometimes a fuse or 2, then TV is like new.

It is much more complicated than changing batteries on your remote. Many consumers try unsuccessfully to do a convergence repair. I recommend finding someone competent to do it for a reasonable price. Typical repair shop charges may be from $400 to $650.

If you are in the Calgary area, call me. More reasonable rates.

You need a remote that can produce the "DISPLAY" button on the Sony remote in order to get in service mode....(you could also carefully move the centering rings on the red CRT to line it up with the green CRT)

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

Could you tell me how to get into the service menu of my toshiba rear projection tv?

Most TV repair shops have a warranty 30, 60, or 90 days. Call him back. You probably have a convergence IC failing or a resistor changing value in the green convergence output circuit.

Mitsubishi VS-50705 50 in apparent convergence problem.

First thing a tech would do is solder around Convergence amps then check to see if you can align by menu then if can not. Change amps and maybe resistors.

Green is tilted

Put the convergence controls at roughly center and manually adjust the green tube for the best pix. Then, go back and set up your electronic convergence and see what that does for you....accordianman
