Samsung UN32F5500 32-Inch 1080p 60Hz Slim Smart LED HDTV -- turning on and off, fix?

SOURCE: Samsung CLP-315

try to do this set of instruction & solution:

1. Go to Start | Control Panel | Printers And Other Hardware | Printers And Faxes. Double-click the icon for your printer to open the Documents window and clear any pending print jobs by selecting Cancel All Documents from the Printer drop-down menu
2. Try printing a test page from the printer, not from Windows XP. Most printers have a built-in test function that's activated by holding down one or more buttons while the printer is starting up. Check your printer's user manual for instructions. If this page prints successfully, you know the problem is either with your connection or with the software in your computer.
3. Check your printer's USB or parallel connection.
4. Try printing something simple from Windows' Notepad. To open Notepad, go to Start | All Programs | Accessories | Notepad, type a few lines of text in a document, and try printing it. If it successfully prints, the problem is with the software program you originally tried to print from.
5. Try printing using Windows XP's generic printer driver. Open and run the Add Printer Wizard. When you get to the Install Printer Software screen, select Generic under Manufacturer and Generic/Text Only under Printers (see Figure 2).
   
6. Select No for Do You Want To Use This Printer As The Default Printer? (see Figure 3). Click Next.
   
7. When prompted on the next screen, tell Windows XP to print a test page. If the page successfully prints, then you probably have a problem with your installed printer driver. Either update or reinstall the driver.

SOURCE: Samsung TV won't turn on- trying to fix it. A challenging problem

I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order (shopjimmy.com and vancebaldwin.com). After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.

Panal damage is a possibility however, you may also try to have a tech replace your mainboard since you have sound.

SOURCE: Samsung 50" DLP TV turns itself off

My Samsun DLP turned off and “Screen Freeze”. Fixed it. How? Well, after reading lots of posts I almost purchased a new $136 bulb but decided to give it one more look. Turns out there’s a small switch inside the TV that needs to be depressed at all times. Samung put this switch there to turn the TV off if the rear panel is removed to protect people from harmful UV radiation. I just moved into a new apartment so it must have become unsettled.

I took my back plate off, pushed the button up and down several times then carefully replaced the panel. Note, the panel has a sort of plastic finger jutting out. Make sure this finger is firmly pressing the switch down. If not, wrap some tape around it to make the finger fatter. Dude, use black electrical tape so you don’t start a fire, OK?

So, my TV came back on and I danced a little jig in the living room. Then I started switching channels and everything froze when I got to channel 68. This didn’t look good. I read more posts about people getting this and simply returning the TV. Oh no! Well, I unplugged the TV several times and got bupkis. Frustrated, I finally pulled the power strip off the wall and plugged the TV into the wall. I got a blue screen and when I switched the channel back to 5 it started working. Danced a little jig. Plugged the antenna power into the wall, got better reception, channel surfed to 68 again (don’t ask), and got screen freeze . . yet again. Why? Unplugged the TV several times and got bupkis.

Then the bulb in my head finally went on. My Samsun does NOT like channel 68 but I could NOT get it back to channel 5. Every time I plugged the TV back in it turn on at channel 68 and froze. Ah, unplugged the antenna again, got the blue screen . . again . . and I was able to change the channel back to 5. Danced a little jig.

Hope this helps sooooooomeone.

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.
