Question about Samsung Televison & Video

3 Answers

I have a Samsung 56'' DLP with occasional fuzzy picture problems

I have a Samsung 56'' DLP HLR5678WX TV. It has been working really well since I brought it new in 2006. Recently I have noticed that the picture color will fade slightly and the picture seems to be slightly fuzzy/stretchy with a hint of red in the picture. Turning off the TV for a few minutes usually fixes it, othertimes it will correct itself while the TV is on. What could cause this?

Is the TV on its way out?

TIA
Thanks

    Some more details: Restarting the TV no longer fixes the problem. Sometimes you will see a red wave on the screen that moves with the picture. I have some pictures but I'm not sure how to upload here. The problem is intermittant, sometimes it will run fine for a few hours, then it comes back. Thought it might be heat related but doubt it as the room temp has bearly been over 70 degrees last few weeks.

    Hi



    Thanks for the reply. I would like to clarify a few things to make sure I am on the right track before shelling out for a new color wheel....You can some samples pictures of the issue I have via http://www.hometheatershack.com/forums/s...



    Notice how on there the 'red' is across the whole screen. Sometimes it will appear just aound the faces within the picture, and like I mentioned other times its just fine. Lately it's been worse. I took it to a local repair shop, but tells me he wasnt able to see the problem even after having it run for 4 or 5 days. I brought it home, it ran okay for about 5 hours, then the problem reappeared.



    Still sound like colorwheel? How can I find the exact part for my TV unit?



    Thanks.





    Amit

Hi..Check that all your input cables are tightly plugged
in at both ends. If that's not the problem, unplug the tv
for a few minutes and replug and see if the reboot helps.
Otherwise it might be a board going out in the tv.
check ot out..
thank u..

Samsung plasma pn50c450b1d no picture no sound


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My lg plasma tv is cutting off the edges of the shows we are watching. I cant find a setting that will take care of it. Can you help


hmm normally these settings are found in the picture settings of the set top box or just a setting in the tv's picture settings now there might be an option to say fill screen that may work best for some or leave the tv in 16:9 some broadcasts may only be in 4:3 at times this is normal broadcasting and not much can be done unless the setting on the picture option is set to fill screen

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.

I have checked cables and different methods of connecting, but the white and red audio out of my PVR appear to have stopped putting out sound.


Go through the setup of the PVR and check the sound settings. It sounds like it's only producing digital audio, that's why it works with HDMI but you want analog, so set the audio to stereo, or try every setting to see what works!

Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.
