Question about RCA D52W23 52" HDTV CRT TV
I was watching tv and my convergence went all out of place , i went to fix it from my remote and the convergence was not on my menu to fix , can you tell me what it could be or is it even worth fixing ; if so how do i go about fixing it myself
Thank you for your time and concern ,
You need the service manual, I don`t know about these particular set, but on Toshiba`s, you had to press the menu button on the set and while holding that in, I think you pressed the red button on the remote. This got you into service mode. If the convergence went out while you were watching it, I don`t think adjustments will cure your fault, it sounds like the Driver chip may have failed which drives the convergence coils on the tube necks. Is it just one/two of the colours?? Is it out in the centre?? Is it out around the edges?? If you do intend adjust anything, make sure you write EVERY setting down first including EVERY mode, It is a VERY time consuming job and even then you`ll NEVER get it perfect. You have to repeat the whole setup in EVERY mode, eg: Widescreen, 4:3, Stretch, 16:9 etc. You`ll also need a signal generator to give you a steady picture while performing any adjustments and when you alter the brightness and contrast, this will affect the convergence also. DO NOT alter the binary settings of the set, these tell the micro what the set is fitted with, eg: Nicam, Freeview, NTSC, PAL etc, etc. If I remember correctly, there are about 300 settings which have to be performed in sequence and when you alter one setting in one mode, this can affect another setting in another mode. It`s a real nightmare, believe me. The only trouble is, if you do start to alter the settings and you find that there is a faulty component, You`ve got to try to get it back to the settings that they were before you started your tweeking. If you do alter the binary code settings of the set, then there`s a very good chance that the set won`t come back on. It took me three days to sort one set out once and even then the customer complained about the convergence. Ian
