RCA r56wh78 Why does it power on to setup

I was working on convergence in service mode. I decided to reset the red and blue. I'm not saying it's the cause, but I've been working on the tv for weeks, I was working n the convergence settings. For days now, everytime I turn on the tv, it automatically starts with setup procedures. I turn on the tv as normal, not service menu, and it automatically asks me to choose english, french, or some other language. I g thr the setup procedure. Everything is fine. I power it off and turn it back again, and the setup starts again. Sounds like a setting, how can I fix it?

SOURCE: Cant realign the color on my tv

It is probably the convergence Power supply usually mounted above the main boards below. Most of them use a STK730-010 amp that is usually the problem, if not some used a little FET instead. It seems that PCB is available probably listed as a power supply rather than a convergence bd though

Do not automatically think you need to go into the service menu. I bet you 100 to 1 that you pulled out a plug or a connector somewhere OR one is not seated into the plug all the way. If the set worked with color before you messed with it, there is not a problem in the service menu. The service menu is not the fix all thing. it is there to make fine alignments and adjustments, and as a matter of fact, messing with a service menu even with the service manual is very dangerous. I have seen peeps ruin TV sets by messing around with the service menu alignments. STAY out of these alignments. they are not going to fix a problem that all of a suddenly comes up. Repair the problem in the circuit first. Good Luck

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

SOURCE: VERTICAL PINCUSHION (NORTH & SOUTH PART OF SCREEN)

Whenever a component in a device is replaced it must replaced with the original part, unless the manufacture says differently.

TV sets have minute control voltages which in turn control something else - in an analog/rear projection they control larger voltages for example. It all has to do with resistors, transistors, capacitors, etc. which make up the circuits.

So even though this might appear to work I guarantee your set is not up to spec.

Screen lookes like colores separating


Here's all I find regarding bad convergence from the techrepairCD:
RCA ~ITC222 D52W20~Convergence bad~~~ITC222~Replace leaky DL032 on
deflection board~~~~~~

RCA~D52W20Y ATC221~Convergence goes out/bowed after on for a few
minutes~~~ATC221~Problem may be on the deflection board. Was unable to
pinpoint where in this case.~~~~~~

RCA~D52W20BYX1 ITC222~Convergence way off after replacing small signal
board~EEPROMS were transferred over to new board~~~IK210 was
defective..transfer the new EEPROM back over.~Remember on these
sets*when replacing the SSB* if there is a small P on corner of
screen*hold volume on remote for 8 seconds after it reaches minimum.~~~~~

RCA~D52W20BYX1 ITC222~Can not align blue convergence* bottom really
bowed* possibly either color after replacing SSB.(Or no auto
convergence.~(Service menu: turn power off for 30 seconds* press vol dn
and ch dn* simultaneously for 8 seconds* set turns on with service menu
options)~~ITC222~In service menu* select convergence. If sensor
calibration was performed when convergence was too far off* it will not
alighn.~Get crosshatch with straight lines* perform sensor calibration*
then attempt convergence alignment again. Be sure to store settings*
then do sensor calibration again.~You must get a green flash of the
screen after sensor cal and a check in the box. RED flash indicated
convergence settings are too far off~~~~

RCA~D52W20BYX1 ITC222~no convergence correction~~~ITC222~LP650
(259271) DP670 (259246) & RP632 (259564) 4.7 3W on convergence power
supply board~~~~~~

R56WH78 convergence problem


Yes replacing the power module will help a lot , Since you have background with computer and some electronics you should be able to fix this by your self you may just need to solder some loosen parts of your television then that should fix it...

Good luck.........

RCA D61W20 Projection Television with ITC222 chassis Here is the whole thing , took this machine apart last night the mirror is in good shape cleaned the lenses, picture is much brighter now! However still...


unfotunatly the itc222 has no convergence ics it uses a series of trsansiitors. the fact that u have some areas of the screen clear may mean you need a technician to do a service alignment. when you go into setup does the convergence crosshairs move up and down and side to side on both the blue and red? if they do their may not be a problem with the power board. ONe more thing if you replace this board you will still need a technician to do a service alighnment

Convergence problem


Yes, the convergence circuit can fail without blowing any fuses. These Tvs are tough to repair because the convergence output devices are transistors and there will be other small components damaged as well. Get an estimate from a reputable service center before going any further.

RCA HD R56WH78 projection TV, picture just got ascew,


You are haveing form the sounds of it convergence problems. I see this all the time on this set at the shop. FIrst question in customer menu under setup do you have the convergence option if not consult the tips and tricks section under fl231 problem. if you do have this you may have other troubles the convergence is controled by three seprate boards.

Picture has 3 images, all different colors (red-blue-green) screen looks concave in the middle top & bottom


This is what is known as convergence..(very common)... first question DO you have the "CONVERGENcE" option in your setup menu?.... if you dont there may be a special fuse issue... if not then more than likely it is what is known as convergence power supply issue. you have complete loss of convergence?
