Question about Projection Televisions

1 Answer

We have a 2 year old Samsung TV model LN-R329D. Yesterday, we stopped getting sound from the TV. We called Comcast and when we put in a DVD, we still didn't get sound and our other 2 TV's are working so we ruled out cable as an issue. We called Samsung and they were no help. They told us to take it to an approved service provider. Any suggestions?

Do an in-depth inspection on your cable connections inside the unit, especially those coming from the main board at JA4002 and JA4003. If you have no loose connectors then I'd say trace measure the sound signal and see if it's present at the amplifier and back through the circuit to the processor. If you have signal and still no sound you may need to replace the main board, Samsung p/n# BN94-00629F available at many distributors like Vance Baldwin.

Follow the cable from the Comcast set top box and see where it is plugged into the tv. Check what that jack is labled and then select that option on the TV menu. My guess is that the tv and dvd are not both on component 2, if the are then the set top box is not connected directly to the tv but to the DVD unit. In that case, if the cable set top box is connected to the dvd, then you might need to put the tv on ch 3 (or maybe 2 or 4) or you may need to switch a setting on the DVD box or remote that selects the TV/DVD option.

Are you using the rf antenna input for TV or 1 of the VIDEO inputs from a cable box or sat receiver. If the latter check to see if you unplugged the audio fron the box White and red wires from box. If thats ok Plug that dvd player into that input using the cabes from the dvd player .If you now have sound change ables from box. if still no sound cable box bad. If still no sound from that input check for solder connection on input jacks. If antenna input is used replace the tunner intv.

My Panasonic TV model TH42PX500U, operating on cable through a cable card, suddenly stopped giving me any cable stations higher than 26! The first 25 work great and then nothing. Sny ideas?


I reset the TV by pressing the on/off and "OK" button at the same time after unplugging and replugging the TV. I also called comcast for a signal to be sent to my card ( I had done that yesterday with no result), so I don't know which of these worked, but I am good to go again.

the person you talked to at samsung is more than likely a customer support rep that does know anything but what his computer tells him. i have seen this symptom several times in many makes and models. if you can give me your full model number i will give you a part number to fix this issue.
