Top 20 Samsung LNT5265F 52 in. LCD HDTV Questions & Answers

We can't detect a faulty board by smell, like dogs do. You should check its circuit. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

can be inverter or the ccfl light itselve. if there are multiple ccfl's probably the inverter or powersupply. check for bad capacitors.

Since it only happens on CBS it is most likely a signal issue. definitely contact DISH

This is a common problem with all Samsung flat panels. The problem is caused by faulty capacitors on the Power board. It is an easy fix if you have basic soldering skills. You can also call Samsung and see if your tv is covered under the class action and they will send a tech out to replace the board.

Either gonna be an issue with your speakers or more likely it will be that you need to replace the main pcb. What is the model and version # for your tv?

Could be a bad tcon and lvds. If not, it would need a new display.

either a bad lvds and tcon or a bad smps

Most likely the lines are coming from a failing LCD panel tab connection. The capacitor problem and LCD tab problem are the most common problem for older Samsung LCD's

try to adjust the TV resolution to fix the issue..It refer in manual..

This sounds similar to a known problem with bad capacitors in some Samsung TVs. Even though the TV is out of warranty, Samsung extend the repair period for affected TVs. Get your TV model and serial number off the back and then call Samsung at: 1-800-Samsung (1-800-726-7864). Explain the problem and let them know that you have heard about similar problems and heard they were being repaired out of warranty. In my case, they sent a tech out and did the repair for free. If for some reason they will not do it, the repair is quite simple for someone who can solder and you can find details here: http://www.thebuzzmedia.com/samsung-tv-capacitor-clicking-issue-and-free-repair/

Most likely your backlight inverter is defective. On a set this big, the inverters should be seperate boards. It could also be leaky caps in the power supply, or a defective mainboard that isn't holding the "BL ON" signal. The tv is repairable but most repair shops will want to gouge you on price.

It may have dying power supply due to bad DC filter caps in the power supply module, look for domed caps first.

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

The problem is in the inverter. Replace all the capacitors in the inverter and you'll get it back to work. The inverter is a module inside wich is responsable with the display backlight. You can buy whole module (inverter) from the internet. Before that you should know: the working voltage (can be measured on the central big capacitor pins located near the connector plug); The number of lamps (see how many pink wires get out to the back of the display). Usualy the LCD tv's have inside two boards. One is the logic board and the other is the inverter. Sometimes these two modules are on the same board. If they are separated, they are conected togheter with 4 main wires: ON (power on command), DIM (dimmer command), NEG (negative), POS (positive wire).

This is common problems for LCD tv,most likely because bad components parts call capacitors on the tv power supply board.That the board,where the power a/c cord plug into it.U have tools like a soldering iron,desoldering pump or roll of desoldering braid also can do basic soldering and understanding basic electronic?Take the tv aparts.Yes,check all over the power supply board for capacitors parts are bulging up or puffing up.By replacing all these dying capacitors components parts,will help ur tv LED power light stop blinking and the tv will work right away.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

View the utube video to repair the tv. Mine did that, and I fixed the capacitors on the power supply. They're available on Ebay for five bucks. Don't be intimidated, it's not hard.

Contact Samsung customer support. They have had problems with bad capacitors in some of these units and depending on when it was built, they are offering a one-time accomodation for repair.

You have 2, possibly 4 capacitors in the power supply that are bulged (bad) that need replaced. If you've ever done soldering or changed components like that then you will be able save a repair bill. See the dome at the top of the caps bulging.

You've got bad capacitors in the power supply. This is a know issue, unacknowledged by Samsung. Get the capacitors off Ebay for five buck. View the youtube video on how to do it. I did mine and it works fine.

Check the value of them by using a Capacitance Bridge. One cannot always tell the condition of old capacitors by the physical appearance but it is a good indicator.

Very small possibilities this problems could causes by the tv power supply board have bad capacitors,that have leakages,that are bulges on it tops and require replacing,that the board,where the power a/c cord plug into it.Check the power supply board anyway though.This problems usally cause by a board call the T-CON decoders board is the problems and it is dying.This board sit in the bottom in the middle of the LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy those refurbishes boards like the power supply board or the T-CON decoders board for the replacement.
