Question about RCA HD52W140 52" Rear Projection Television

1 Answer

Weak Signal ..

The TV works fine .. turns on .. but I am hooking up cable with no cable box and all I get is weak signal .. when I run the assisted setup it completes and it tries to search for channels but it completes and none are found .. when I mess around with the signal type the channel comes on for like 2 seconds and then goes off again ... This is most likely something very easy to fix .. but it is driving me insane ... there is just a direct connection from the cable jack to the antenna A .. nothing else is connected to the tv .. and I have tried Antenna B as well .. thanks in advance Adam

Sounds like you have a bad tuner. The most likely cause on these RCA's is a loose RF antenna input connector. A bypass for now is if you have a VCR use it as the tuner and then connect it to the TV using the composite video inputs. If that faisl as well then you have a bad signal board.

Weak or no signal
Either the connector on the set is bad or something is burned out. Try connecting to a tv or ext antenna and see what happens.

Our tv looses it sound as the picture breaks up...many a time it say weak signal
check your signal source, make sure all connections are good. Check that the signal is good at that location with another TV if possible. Check your cable connections, or antana, if using a digital converter box, check those connection as well. if running rabbit years, try to get it as high off the ground as possible. I you have cable or satalite, call your provider for assistance as it is a weak signal.

The screen shows ''Weak Signal'' and no picture, even though audio is coming through from both the Cable DVR box and Blue-Ray player. The cable box connects to the TV with an HMI cable - all five TV inputs...
Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.

I hope this works for you.

Weak or no signal
you would need to know if the tuner is picking up analog signals in the air well( stick a wire a little bit in the tuner connection to see if channels pick up good or use an antenna , if so there should not be a problem with the cable being hooked up to it , if there is a problem even with an antenna then the tuner is bad and will need to be replaced , and the cable could have caused it to go out , but make sure that the tuner is working or not first.

No signal converter box.
Why is this in the computer section?

Anyway, don't exchange the box just yet! First, can you access the converter's menu? Because mine automatically comes up with the "no signal, call customer service" message, but I can access the menu fine -- so the hook-up is not the problem. If you can access the menu, let it autosearch for you, because mine can't be used until I do this. If you get the "weak antenna signal message", refer to the user manual to find out how to check your antenna signal strength; if it's in the weak range, you have to buy a better antenna, most likely from the official source: http://www.accessHD.tv

You can always exchange the box and repeat the process. Getting the "no signal" message is a good indicator that you've hooked everything up right, especially if it's accompanied by a customer service number. You can email me at [email protected] and I'll try to help you troubleshoot the problem if you like. I'm up all night.

Weak or no signal message
  1. Since my problem (Samsung/Comcast) began with a channel selection button pushed on the TV remote when it should have been pushed on the cable remote, I figured the problem lay with the TV.  Although I was getting the "weak or no signal" msg., the actual signal strength bar graphic showed it to be strong. Disconnecting did no good. I surmised that the TV was simply not recognizing the box.
  2. I looked at the manual for my Samsung 750 model. 
  3. Page 20 discussed "Selecting the source". I accessed the TV menu and selected "Input", then chose the "HD..." item from the highlighted list. Voila! My tv works again.

burning resistors rca tv model-HD52W140, resistors R14705,R14718,R14719-burns out-fed from flyback I have a problem with resistors r14705, r14718, and r14719 burning. I replaced the r14705 only to find out the other two started burning as soon as I turned the power on. It was stated in an earlier solution that the flyback was burned out. What exactly is the flyback and will replacing the other two resistors fix the problem. Do you have the specs on the r14718 and r14719 resistors?
