If there is no Menu button to your TV, you must have its remote control to select inputs.

could be a blown fuse,or power cord could be bad.

All relatively new TV's no longer have a vertical hold control neither a horizontal hold control. The circuits are locked on the correct frequency
by phase-locked loops. (computer controlled)

its just easy changing the fuse *behind the monitor)

generally Samsung makes great units. but its definitely not worth fixing. recycle it and indvest in a new unit.

Yes it does.

Includes built-in ATSC/QAM/NTSC tuner for off-air HDTV and SD (standard-definition) reception

Accepts high-definition 1080i, 720p, and 480p signals from DTV set-top receivers and progressive-scan DVD players

Side-panel A/V hookups and controls allow easy connection with a camcorder, gaming console, or other device

Q. is there any particular colour or shade to this square , and how long dose it stay on the screen.?.
Sorry no answer to the problem yet but if you answer these Q. for me I will get back to you on it.P

It may be worth it to fix it. Could be something as small as a bad soldering connection. Unless you have a lot of ability with electronics most consumers would be unable to fix a problem of this nature. Also most times it isn't worth it to repair. You can go to craigslist.com and find a used replacement for 40-50$ that would most likely be a better tv. Though I would still call a professional or bring it in to a nearby tv service center as It may be a cheap fix and you can get an estimate for quite cheap and know wether it will be worth it or not. Another easy fix, would be to buy a 5.1 surround sound system. You can get them at walmart for as little as 40$ to 60$. Just have your audio go through the stereo instead of your tv. If you need any further assistance please let me know. Also please take a moment to accept and rate my solution accordingly.

Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made.
For example:
A Motorola Cable box needs to be set up to go to a wide screen or zoom when an analog signal is detected.
Some Dish Network boxes have Size buttons on their remotes and also in their main menu.
It's difficult to determine the repair without knowing the types of the peripherals.
Hope this helps.

If it's not yet a year old it should have some warranty - take it to the shop.. It's probably the HOT (Horizontal Output Transistor) which have been a problem child in this series all the way back to the TXP2745... But don't even crack the case on this one if it's that new - labor might not be covered but parts might. In any event replacing the HOT is not a difficult or expensive job.

Dez,
The ticking indicates a feed back on the power supply - most likely the shutdown circuit itself because something up-circuit is shorted. MY first guess would be the HOT (Horizontal Output Transistor) - Second guess the FBT or Flyback Transformer...
I might have the service manual for that, just email me personally and make it clear what you're after. I get nearly 3000 emails a day and I be real lucky to remember what this is all about when I get the mail...

PS Go online and download Pando... It's a free download and the best way to send large and/or multiple large files over the net...

get it looked at mine was doing the samething until eventually it never turned back on...

You have problems with your power supply filters. I'd suggest you to change the mainfilter, that is the capacitor just after the ac rectifier and the b+ filter, that is the capacitor at the output of the smps, and then vertical filter and video filter. These are all capacitors with higher microfarad ratings, if you are not much comfortable, it's better to get some help from someone who is familiar with these. Pay attention not to reverse the polarity when changing the capacitors.

it is not remote problem please check the following 1 speaker or its wire for loose 2 check supply to sound section 3 check loose contact or loose part or print. 4 check for loose connector 5 check audio ic 6 check for signal to sound section ic is coming. hope this will help.

what is the question

If you are using cable and the signal is connected to the TV through the regular cable wire, then the TV must be in TV mode to work properly. If you are using a cable box with that TV then the TV must be on channel 3. If the screen shows AV 1, then the TV is in the AV mode (red, white and yellow RCA jacks), and you most likely accidently hit the INPUT button on the remote. Pressing 0 3 or INPUT a couple of times on the remote should bring your picture back.
