RCA D61W20 Image Turns on and Off

Hi, every one, im just trying to find whats going wrong with my TV, just to make sure im not paying a lot to my repair guy.
The image on the TV starts to go on and off and sometimes it goes off and doesnt come back for a while. but the image comes back after a while. During all of this the sound stays on.
Also whenever a turn it on when it was off for a long time I have to wait a while until the image appears, i can see the green light on and the sound stays on but the picture is off and on.
Please if anyone can help me out i will sure appreciate it, my email is rodmorf@yahoo.com

    I went ahead and open the TV and i found rat droppings and urine on the main board and near the DVI chip, try to clean them and it work fine for a few days, but now suddlenly the screen went red and blury and shut itself off, i unpleged like 3 times and stil made the same error, until i tried to switch the signal input, that made the image come again slowly when i was switching from input sources, you know, from DVI to Com 1 then Com 2.

    The problem its not showing up right now, but after all this my TV is showing a light blue/greenish stain on the center of the screen, and sometimes the image is going on and off.

Sounds solder related. I would guess the vertical output IC or flyback needs resoldering, As the vertical will shutdown the picture if the solder looses contact, and the flyback feeds the filament voltages to light the tubes. Solder repair is usually the cause when you lose picture but have sound.

    the urine could have caused some arching between components and that in itself is often enough to cause the solder connections to fail. I would try inspecting the solder for any that appears dull as thats an indication for cold solder

It could be the flyback transformer or several other items all on the deflection board. Were any of the caps you replaced domed up on top?

You could have shorted Yoke and if so you have to replace all 3 yokes another thing that can cause this is Capacitors on Deflection board cp150,cp114,cp120 If cp150 2200uf 16v is puffed up on top then it is bad ,so replace all 3 caps other 2 are 220uf 35v.

RCA D61W20 Image Turns on and Off, Rat Droppings


im sure that the rodent contamination is the root cause of your problem. but the blueish stain does it look like a smear? if you that is most likely a phosphur burn in the face if the CRT. it cannot be fixed without replacing the CRT. i suggest living with it or putting tv on the side of the curb.
