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

Re: Weak Signal ..

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.

Our jvc tv model #HD-70GC78AAA says weak signal

Its possible its the signal source (cable, satellite etc) if using the coax input--the tuner in the set could even be bad.

If rear inputs for DVD etc function well you may be able to get around this with a box with outputs for those inputs on the set--bypass the problem.

I get a weak or no signal on HDMI only (all other inputs work fine). Made sure the cable box was working fine, tried a new HDMI cable and still nothing. Any suggestions?

Was it working before? HDMI is a weak signal by nature, so longer runs may not be possible. How far are you going (how long is the cable)? Are you running this HDMI cable by many other cables or perhaps in the presence of an electrically noisy device such as an electric motor? Also, make sure if you are trying to hook up a computer or any device not usually meant for use with televisions that it is HDCP compliant. What is it you are trying to hook up? Have you tried other devices? With the same cables? You should also be sure both devices are powered down after the connection is made and then powered on first the television and then the other device. If that does not work, power both down again and power the device first and then the television. HDMI is very picky about many things. You may also have to check if your television set has a software update at the Samsung website. Another thing is that the output device may need you to change it to output to HDMI in the menu. Try hooking up another television with it and then try the other. Post back if you're still having trouble. Good luck.

After reviewing the service manual for this set, the problem is is in the DIGITAL BOARD. To get the right Digital Board you will need the Version number of the TV.

Tv picture is pixalated (blocking)

it probably realted to a weak signal from source(antenna, cable or satelite box) if a direct source like a dvd player works fine its for sure your source.

I recently bought a converter box DTA800 to go with my sony tv Triniton mod.KV-20FV300. It doesn't seem to work; programing, set-up. Please advise.

Ah, the problem is likely your antenna. Make sure everything is properly hooked up, and that your TV is on and turned to either channel 3 or 4 (whichever the unit requires, or you can try both and see which works) then turn the converter on, and check the manual that came with it for a way to check for your antenna's signal strength.

If your signal is good, then use the menu button on the remote and look for an "autoscan" feature, or "autoprogramming", something along those lines, and let the unit look for channels for you (mine requires this before you can use it, not that it matters because my antenna signal is weak). From there you can access the channels manually.

Hope this helps.

RCA Scenium HD52W140

I cannot think of anything easy that would cause the symtoms you are describing. Your power supply is working and the deflection bd is good because you have HV. The problem is signal related and all of this circuitry is on the SSB or small signal bd. The difficult thing is when replacing this bd. you must have RCA's chipper check to download all of the ssb eeprom settings so they can be uploaded to the new ssb. I'm affraid you will need a qualifier RCA service tech for this problem.
