RCA D52W20 Blue Tube doesn't power on

I have no blue in my picture at all. The red and green works ok. Every now and then the blue tube with turn on but it seems to be getting rarer. I opened the front panel and seen the 3 little CRTS? The little yellow dim bulbs. Those were all on and I stared at it forever to try and notice a difference to see if there were any resistors or anything that looked burned. Also, whenever the blue tube does not work it takes longer for the TV to turn on. What do I do?

Re: RCA D52W20 Blue Tube doesn't power on

From your description it does sound if the blue crt has failed. But it can be the crt board or a high voltage issue. intermittantly like that could be a connection problem. is there any hissing ..cracking or smells?

Picture flickers every few minutes

There are several possibilities. This model is based on CRT (picture tube) technology, and has a high voltage circuit. This circuit consists of three heavy wires, one from the side of each picture tube (red, green and blue) going to a single connection block. There is another heavy wire from this to the high voltage transformer on one of the circuit boards.

First, unplug the set, and wait 20 minutes to make sure everything is cool and residual high voltage charge has drained away. Check the wires at the connection block to make sure they are not loose. There is usually some sort of retainer clip to lock the wires in place, make sure these are not broken or unlatched (sometimes they get brittle with heat and aging). Frequently these are covered with a thick layer of dust held on by electrostatic attraction; gently vacuum this off. If all looks good, plug in the set, and wait until it's dark outside. Turn on the set with the room lights off, and look at the high voltage parts. If you see a blue corona glow or sparking, that part has an insulation breakdown problem or a bad connection. It is normal to see an orange glow at the bottom of each picture tube, and you would also see the three colors of the picture coming out of the tops of the picture tube. WARNING: do not touch the interior of the set while it is on, especially not in the dark.

Another probable cause is a cracked solder connection on the power/deflection board (the one with the high voltage transformer on it). If the flickering is one color rather than white or a momentary darkening, the problem is in one picture tube circuit (yellow -> blue dropout; ->cyan -> red dropout; magenta -> green dropout). The picture tube circuit includes not only the high voltage (second anode) section, but also the picture tube drive connection on the base of the tube all the way back to the video processor and switching circuits.

Sound, but no picture

If before it was going rather bright red or a version of that--it is related to the circuit for the red picture tube this set uses---the tube itself or the circuit board that plugs onto the end of that tube.

If bright red, green or blue screen set will detect too much current being drawn and blank or turn tubes off; not likely a do it yourself repair and this set is prone to this and many other problems---Just Google the model number with "problems" and see what I mean.

Almost certainly the blue picture tube is bad. This is a huge job to replace and quite expensive. Generally it is not worth doing.
