Re: rca projection tv has no picture or osd
This is not a bulb tv set. it is a 3 crt picture tube projection tv. if the tubes are glowing at the necks then slightly turn up one of the screen controls to verify if you have a raster. if you get a glowing line across the screen left east-west then you have a vertical sweep problem if you have the whole screen lit with a raster then you may have a bad jungle ic.

If no arc into a bottle with the HV wire removed and inserted the trouble is before that. Set is prone to some nasty problems---a number (about 12) similar large diodes fail all over the set---have to check the voltages to know as they will test ok even with a diode tester.
Make sure you removed the right wire---ALSO VERY COMMON is when any of the HV wires into the block are inserted they bend over and will work for a while but sooner or later cause issues---you would be able to see this if disconnect the block and remove each red wire---they slide down and plug in---find one or more folded over inside the tubes and you have found your problem.
The Block is now very cheap --seen them for 20 dollars.
I have a problem with the colors on my RCA Home Theater model #P60752EB. I believe it to be faulty tubes or something cause my green and my red color is messed up to the point it will not come in at all.what should i do to resolve this problem without replacing the tv
Sounds like the flyback, can you look on the rear tag and let me know which chassis you have and verify your model number and I will post which flyback you need as well as where to get a replacement with free tech support to help you install it.
The 169 is an old chasis but a good one. Many chronc problems can cause these symtons. No high voltage because of bad flyback, or HV spitter defec is the most likely, but there are chonic caps that fail in the power supply as well. This problem will most likely need the assistance of a qualified service professional.
Dir TV projection Techcions, I own RCA Model:P52937 Chassis No.PTK195M26B. After a big flood here in Chicago, my basement got flooded and my projection TV was in water up to 1 foot. Befor I turned it on, I dreid it out perfectly, then, I turned it on, and a couple components from the power supply got burned up to the point where I am not able to read the part numbers that are on it. I was wondering if you have this kind of chassis and model service manual for this projection TV, or conponet part number i location 101 on mother boatd power supply. Thank you in advance, Darius
