Question about Samsung LN-T5271F 52 in. LCD Television

1 Answer

My TV has a severe flicker/jitter in the bottom left quadrant of the screen. How do I fix it?

I have a Samsung LN-T5271F LCD TV that is about four years old. It has a screen problem that I will try to explain. It has a severe flicker/jitter in the bottom left quadrant of the screen. It has four equal horizontal bars on the screen. The top bar does not flicker/jitter, but the further down the screen you go the worse it gets. It is also does not flicker/jitter on the far right side of the screen, but gets progressively worse towards the left of the screen. Any suggestions? Thanks.

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.

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.

SOURCE: TV turns off and then on again every five to ten minutes!

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty by extended plan, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Call Samung customer service, they are doing this repair for free. I had the same problem at 11 months, they replaced the power supply board under warranty. At 2 years I had the exact same problem again and this time they replaced 2 - 50 cent capacitors on the power supply board. It took the repair man less than an hour and he had the replacement capacitors on hand. The original board and the replacement board they gave me had capacitors that were faulty. Hopefully these new capacitors will last. I have to say that I was thinking (no more samsung products for me) but I got excellent customer service and they admit that they had a faulty product and they accepted responsibility.

SOURCE: samsung lcd ln-s3641dx/xaa four bars

Hello,

All lasma an lcd ts have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em.


Good luck.

Samsung TV now takes over 30min to come on


There are a number of Capacitors on the IP/Power supply bd and they have gone bad. Replaced them with the proper Capacitance as the old ones are BUT get the 35 volt Caps. Going from 10v to 35v will fix this problem.

LN-T5271 will not turn on


Hello,

Its sad to hear that your LN-T5271F TV isn't turning on. Sad to say that there are no user serviceable parts inside (unless you are a professional TV repair Guy) There's probably a blown fuse or a bad capacitor inside. The only way you can tell is to open up the TV and use a tester. I don't recommend that you to that yourself because you might end up spending more. Bring your TV to a local repair guy and have it fixed.

I hope this helps. Have a nice day.
