Question about RCA HD56W58 56" TV

1 Answer

Auto Converge Hi, We just bought this Nice tv, Onl;y to get it home and relize that it needed to be converged, becuase when there is text on the screen particularly on the sides and bottom of the screen, you can see the blue and green way off, which makes it hard to even read the text. To I figuered no problem i can just activate Auto converge... Yet as soon as i tried to auto converge a message pops up saying Cannot perfoprm Auto Coverge: Sensor is unresponsive! What does this mean?? How can i fix it...? Im actually a technician, but not very experienced with projection tv's....I mainly work on Arcade Games, and Slot machine's... Overall the Picture is decent and the converge seems fine for the middle part of the screen ,,,Is there a way to do a Dynamic Coverge on an RCA like you can in Mitsubishi??

Re: Auto Converge

If the message "sensor is unresponsive" crops up then the problem is definitely electronic and lies somewhere in a loop that starts near the tube base, goes to the main board and back to the tube base. However, you can try to do a manual converge by adjusting the ring permanent magnets on the neck of the tube (right behind the scanning coils) while something is being displayed. Normally these magnets are secured with a clear glue to minimize drift. Use a heat gun to soften the glue and then turn the ring magnets around until you are happy with the picture. As you know, this part of the TV has some pretty dangerous high voltages so try to keep your left hand in your back pocket while doing these adjustments with your right. Good luck.

The convergence chip is already faulty try to replace it. Remove the back cover of your tv but be sure to unplug it before opening it, you will see the convergence chip attached to a large aluminum plate this plate is the heat sink be careful when replacing the convergence chip because you may accidentally damage the pcb and cause much serious damage to the tv. Or try to contact a technician to do it for you and save you from stress good day and best regards.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Unable to converge vertical blue gun

The convergence IC's probably need to be replaced. Unless you are savvy with electronics, I would not attempt to fix it. Call a professional. I would estimate a repair cost of aprox. 280.00 to 350.00.
Hope this helps,

Sony Hi-Scan 1080i 52" projection TV colors won't converge

No you will need to repace compents. Do you know how to solder and use a meter? If so I can assist you with the repair. If not you will need a repairman, he will cost you about $300-$500 for the fix.

Sensor not reading problem is due there is some obstruct between sensor and projected light beam. Check any disturbance are there and clean the sensors. Cleaning work is done by the technical persons only since it is sensitive area. Try another method also by changing the TV aspect ratio is 16:9 and then select auto convergence method. This is the one chance is there before you call the technical person
