32v434t My RCA 32v434t will come on after 10 min of trying if its got a dark background such as blue or Black like the space between commercials and it will stay on unless the picture turns a bright color such as Yellow or White, I had it at the shop 4 or 5 yrs ago after the HV transformer blew they removed the old one put in a new and we got it back home it would come on for bout 15 min didn't matter the color and I took it back and they fixed it had a transformer set wrong, I brought it home worked fine for 2 yrs and few days ago it started this, its got a good picture when its on, could the transformer be off set again and if so can I reset it at home?

Perform the head cleaner mantenace menu and feed roller cleaner then make a test print.

If half screen is affected it will be either a board (LCD and Plasma have different names) but in those one board drives each side of the screen unit--worst case is the display panel itself which is fatal from a cost point of view.

Inkjet printer inks are dye-based, and that's the reason.

Perhaps this will help explain things. You know those little boxes of food colouring you can buy in the supermarket - the ones that have four little bottles of colour - red, blue, yellow and green. Within reason you can combine these to turn white icing into most colours. Use nothing and the icing is still white or use everything and the icing will go a black-brown colour. Use a couple of drops of red and blue and you'll get purple.

But if you start with black icing, there's nothing you can add that will make it anything but black.

It's the same with your inkjet printer - because white is obtained by not having any ink print on the white paper. But of course that only works when the paper is white. Naturally you'll get different results on all colours of paper, decreasing as the paper gets darker in colour. Print blue on yellow paper and you should get green printing.

The only way to print in white is to do what commercial printers do - use opaque inks and include a white ink in the process. And as far as I know there's no commercial ink that will do that with an inkjet printer.

I can hear lots of you muttering "Rubbish. Of course you can print light colours on dark paper." Well all I can say is, have fun experimenting, but you won't be able to do it.

About the only way to achieve the sort of result you may be after is to print the job then trim it and paste it in place. For instance, if you want to print onto a black or dark-coloured T-shirt then print onto white transfer material, trim the print to size and iron it in place.

The color problems are caused by cracked/broken solder joints on the circuit that controls the display.  Usually this is located at the back of the tube on a small circuit board. Your description suggests that only the blue signal circuit is intact. I suggest these joints be resoldered for more strength.
It's a possibility that another IC senses this problem (or another one) and then shuts down the system.
Resolder those joints and see what happens.

If you hear the high voltage try to come up and set shuts down in 2 secs it could be your FBT also these sets have alot of poor connections chassis should be resolder.

ohh noooo call a good repair man...
tap on the green crt and check for liquid on the board

yepp. throw it away and buy something better than RCA. these sets are the worst RCA ever made.they dont even supply parts during the warranty anymore........

The H.O.T. Transistor number (original is 2SD3402 (which is no longer available)) it's replacement is the 2SC5902.

The H.O.T. Transformer part Number is RCA 271996

Has anyone confirmed what the problem is? Mine wont turn on. The red light next to the power button just stays lit when pressed.

RCA 32V434T likely has a bad flyback--#271996. RCA 32F531T flyback no longer available,#262343 Fix one,dispose of other.
