Question about Samsung Televison & Video

1 Answer

I turn on TV and it says no signal. When I change input it goes on one time. Then when turned off it goes back to no signal and there is a long delay in changing any settings. It is like an overloaded computer. It is a 40 inch LCD 8 months old. They have changed all the parts two times and the same thing happens.

    We are using a Time Warner box and they check it out and it was fine. I will try to attach the set to the cable directly and see if that works. I will also try another input. It seems like the TV hangs up after the first set of instructions from the remote. It takes a few minutes for every new request.

    Turned on TV to try your suggestions and it worked perfectly. It held its input setting and did not say "no PC." Strange. I still called Time Warner and scheduled a call. We ran a test over the phone and on the box and it seemed fine. It may be going in and out. Thanks for your help. They extended warranty for 90 days and I will wait to see what happens.

If the Samsung svc. center replaced all the parts twice and it still does the same thing, look elsewhere for the problem. As a samsung servicer I know their parts dept. is very reliable. Few defective parts. It sounds to me like you have an issue with bad cables. Whichever you are using, HDMI, component video, s-video or plain a/v cables, try using a cheap pair on another input for a few days and see if that doesn't improve things. If you are using tv tuner to pick up stations, try the other r.f. input on the set for a short time to see if it is only happening on a certain source. Odds are very low you got two defective boards with the same problem. Suspect external cables. Good luck, Russmann.

    The only other thing I can suggest is a firmware upgrade which is avail. from samsung on most LCD models. Although if you had a main pcb replaced already, I would think it had the update. Not to offend anyone but I can't even count the number of times that the cable co. said it wasn't their fault and were eventually proven inaccurate. If the problem doesn't appear from another device, suspect cable box. I have personally on at least 25 occasions experienced time warner boxes having problems passing a decent HDMI signal. Cable cards ****, too. Good luck, Russmann.

Well not sure what is causing the problem but i think the simple solution is to change your power management settings. I set mine to shut off as well if there is no input signal but the only way it goes to the 2 min. warning is if the cable box is off or its not getting any signal.

I have an r52wh74 tv. cant get it to display 720p

Hello Matiki64:

Yes this television does support 720p and 1080i. Hear is something that might solve your problem or at least get you going in the right direction.

Problems with DVI-HDTV Connection
• Make sure the DVI device is turned on and the cables are firmly connected. If problems still occur, turn off your device. Re-connect
your device. Reset the power by unplugging the power cord and plugging it back in.
• If you are tuned to the DVI-HDTV input and you’re receiving Unusable Signal message on-screen, contact the manufacturer of the
DVI device for further assistance.
• If you tune to the DVI-HDTV input and you see snow, the video goes in and out, or the video takes a long time to appear, your DVI
device is having trouble sending video information to the TV. Re-connect your device. Reset the power by unplugging the power
cord and plugging it back in. If problems persist, try connecting to the Y Pb Pr jacks instead if they are available or contact the
manufacturer of the DVI device for further assistance.
• If you have bars on each side of your picture, the device you connected might have a switch or a menu option allowing you to
change the picture format output that will fix this. Choose either 720p or 1080i.

Tv goes off, then comes on, and volume goes to max

OMG! Verizon Fios at it again with changing boxes! Well let me tell you if you do not loose signal on a DVD using these same inputs ITS NOT YOUR TV!

Whats going on is further into Verizon system you loosing the signal from the VDSL slam outside in the pill box. This thing will need to be replaced and they are going to blame your TV until you just give up and buy a new TV only to figure out its not your TV.

1. Call them back
2. tell them to check there network
3. if that dont work tell them to check it again
4. if you have HDMI use that instead of the scart connections.

I hope you have luck with Verizon Fios there internet rules but there TV service is sub par!

Does not pick up cable satellite signal

Do you have the satelite hooked threu the regular cable input? If so hook it thru one of the video inputs instead; composite video or component video. the picture and sound will be better and you will be by-passing the problem area of your Tv ( the tuner).

TV screen goes blank but power stays on

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Redish distorted cable picture until I change input source and then go back to cable input

When you say brand new, just how new is it? Your unit could be covered by the warranty. Certainly something worth checking into. If it works fine on all inputs except cable and the cable box has been changed your problem is probably in the digital receiver in the TV. This is something you will need a qualified repair tech to look at but should not be an expensive fix (compared to the cost of the unit). First make sure it is not covered under warranty. Free is still better than having to pay! Good luck.
