You may be missing a +/- supply voltage to the convergence panel. At connector 7C3 check the following pins Pin 2, +26vsw; Pin 3, -26vsw, Pin 4, 16vdc. The 16vdc is regulated by IC 4006 to +5v. The -26vsw. is regulated by IC 4007 to -5v. If one or more voltages are missing at 7C3, they are generated in the power supply panel. The +26vsw. is protected by FX3460, a 5A fuse and output thru CR3419/L3408. The -26vsw. is protected by FX3461, also a 5A fuse output thru CR3420 (checked at anode end) and L3409.

The parts for the +/-26vsw are located to the left of TX3402 as viewed from the top. The 16vdc comes thru RX3210 (1ohm, 1/2w) and CR3206 located to the left of TX3204 and behind the H.O. xister. Also, the blue tube is purposefully adjusted slightly out of focus to give a better over-all color picture.

if you dont anderstand this, have a technician check this out for you so that he will automatically see where the problem is.

thanks for using fixya.

Hi the problem you are having is going to be with the convergance ic they will need replacing this is a common problem with this type of tv and tv repair shops are familiar with this type of repair but getting this done will solve your problem and should last a good 2 to 4 years after repair has been done

Rca hdtv 52inch will play fine then picture goes black but still has sound.. after a few mins.picture will come back on , and will play fine could last all day or may go out again in a few mins.


My tv is relatively new, but the bad thing is that I had an old; big screen tube type rca model; home theatre, that was heavier than a car, and it went out, due to the cracking and popping sound, off sometimes, and back on.
What is strange is the new tv now, the hdtv, light weight, about five years old, is doing the same thing. Actually, now, the power will not even come on. The lcd green light in the front goes on and off.
Take no offense, but I thought I would not have these problems anymore. What do you suggest?

RCA REAR PROJECTION 52inch 1999 model


get a new cable. the connector on the cable is bad.
the center pin of the cable connector is the signal carrier, and the outer jacket is the ground. so if wiggle the cable and the cable and the pic become clear, then it is definitely is the cable.

RCA D56W20 picture problems


More information is required to properly troubleshoot this problem. How is your television connected when you are watching HD? Do you have HDMI for this, do you have a satellite or digital cable box? For analogue are you using regular coax antenna (cable TV), or are you going through a cable or satellite box?
This could be related to the aspect ration setting. perhaps you ahve changed your aspect ratio from 16:9 to 4:3 or some other setting. If you are connected via HDMI, then the digital signal may be "normalizing" your picture during HD, but reverting back to the other setting.

Check you video settings very carefully. HD televisions are very difficult to tweak properly.

RCA 52inch Big Screen.


On your remote push "Info" then push right or left to get OFF zoom mode, Cinema view looks pretty good.
