Question about Samsung LNT5265F 52 in. LCD HDTV

1 Answer

Self- reboots at start-up, then shows picture but with pink dots.

Samsung LNT-5265 52" LCD 1080p turns on strange, then pink dots appear with picture. Upon turning it on, I can hear it turn on, but the red light just flashes 5 times, then the set turns itself off and back on again, only to flash the red light 5 more times and turn off again. It does this about three times before showing a normal picture, but there are pink dots all over the screen. If I turn off the TV and turn it back on, the pink dots dissappear and everything is okay. The TV is mounted on a swivel, and I'm beginning to think it got swiveled into the wall by one of my kids when I was out of the room. Aside from the obvious "watch your kids better," can anyone offer any insight as to what this might be and a way to fix?

    Okay, so after waiting patiently for a response, the TV now takes like ten minutes to stop turning itself off and on before it will display a picture at all. I have been reading up on others with this problem, and everyone seems to recommend changing some capacitors, but before I take my set apart tomorrow can anyone tell me what capacitor(s) I'm looking for, what kind of steps I'll need to take, or maybe what tools I'll need? I'm fairly smart and mechanically inclined, but I definitely need a push in the right direction before I attempt to fix my $2000 TV

    Good news: like I said yesterday, I went ahead and uncovered the back panel of my TV today. After removing another metal cover inside I found roughly ten capacitors of varying sizes, but thankfully only found two that appeared blown. They were 10 volt, 1000 micro-farad, 105 degree Celsius caps, and I had to call around a bit to find some since Radio Shack doesn't stock these. I got my caps at a marked-up $5 apiece, a new 40 watt soldering iron for $10, some 60-40 resin-core solder for $5, and a solder ****** for $5. I took the blown caps out, put the new ones in, and the TV fired up like new for a total of $30 and some easy detective work. Note that I have never repaired any kind of circuit board before, and I thought this was pretty easy with some help from a site called Good luck out there, and thanks to all the "helpful experts" at FixYa.

It sounds like you have a Power Supply Board problem. The PSB 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 CM811, CM812, CM817 & CS806; 1000ufd 25volts. It is the board to the left and you notice that the four cap tops are swollen.
It is easy to replace get a stanard solder pencil and you are in business.

Thanks for using FIXA, BIG IRISH.

Testimonial: "Thanks for the advice, guy. I already replaced the 2 that were swollen, and now my TV is awesome again. Will replace all caps if it happens again."

MY Samsung LN-T4661F 46 Inch 1080p LCD HDTV is having several issues. For the last year or so, upon initial turn-on, it takes several minutes for the TV to turn on (about 7 or 8 beeps). When it does turn...

Taking several minutes to turn on problem is usually due to bad/unstable DC from the power supply, which can create a lot of strange symptoms. That willbe the first palce to look.
Please read mu guides for details and post back what you find on the power supply section first. We need to fix the delayed turn on problemfirst before trying to fix other symptoms.

Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.

Dots in picture (red, pink, etc.). Will go away after power cycling the set. please help.

is this a Samsung LN or LNT model?
if so there are two or three bad capacitors in the power supply...all of them located in upper right hand corner of the board between the heatsink up there and the wiring harness that jumps over to the main board. Look for the capacitors that have their tops buldged up.
Change them with same value
1000uf 10v or
2200uf 16v
or however they are marked (different size screen used different value caps)

Samsung 46" pink dots

I had a problem with the TV going on and off several times before "warming up" and then having pink dots. I would have to reboot to get rid of the dots. I called 1-800-SAMSUNG and reported that I had problems with the capacitors. That is what was causing the problems - cheap capacitors and Samsung is aware that this has caused many TV's to malfunction. My set was not under warranty but Samsung sent a technician across two state lines to fix my TV. As long as the problem is the capacitors Samsung will cover this service call 100%. My TV is fine now. BTW - capacitors which are sold in Radio Shack are not expensive. Why Samsung chose to put the cheapest Korean capacitors in their expensive TVs is a mystery.
So if your TV need warming up and has pink dots on the screen - call 1-800 -SAMSUNG and tell them your capacitors are malfunctioning.
