I have a rca projection tv model number p52750wk and while watching tv today the sound just shut off. It has a good picture but no sound at all on the tv speakers or the external speakers. I came back on once by itself for about 30 seconds and then the sound quit again.

All projection TVs for RCA
are DLP TVs, with that in mind these TVs have a lamp inside that produces white
light. The color wheel is the one in charge of giving color to that light. Regularly
the color wheel last between 2 to 5 years depending on the daily tv use. Most of
the time when the central barring of the wheel is loose, unstable, or out of
place it will cause the edge of the wheel to make contact with the housing,
producing that whining,
whirling, screeching or hissing sound. These sounds can either produce just a annoying
sound when watching tv or can cause the tv to shut off. When this happens you’ll
have to replace it, if you want to know where to buy, you can look in ebay,
there are many parts you can get at very good bargains, the only thing is that
you buy at a high risk of the part not working ( I had a bad experience). The other
option is to buy at an electronics store online dedicated at selling tv parts,
some can help you trouble shoot your problem and others may have tech support over
the phone (personal recommendation: Discount-Merchant.com ). And last remember
to search your part by part number, NOT by model number, two TVs with same
model numbers but assembled on different dates ( different generation TVs )
will have none compatible tv parts inside, so be very carful.
I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson
three strikes and it's out... rca does this, it is just showing it has tried 3 times for you and untill it is unplugged it won't try again.. you need to provide model #.. could be a few different things
hissing usually meens you have high voltage...that's good but then what don't you have?
ctc 169 - 179 could be high voltage divider... need more info
dear friend your tv has a defective fly-back transformer 99 times out of 100 that is your problem.
get the model number and call your local electronics parts distribuitor to see if they have it, if not call tritronics 1800-638-3328 they probably have it and is not too expensive.less than $25.00.now when you get here is the million dollar question can you do it yourself? if you can't call the repairman and by having the fly-back that will decrese the cost of the repair, is just the labor.
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 beeping sound is most likely the high voltage generator needing replacement. This is a fairly easy job if you have some tech support to discharge the picture tube. You can go to the following link and leave them an email with your model number and your symptom and they will email you back with the part you need and they provide free tech support with instant messageing so you can do the repair yourself. the HV generator takes about a half hr to replace and takes only the basic soldering ability. heres the link. http://servicemanuals.vstore.ca/
