SOURCE: part number for the samsung le52m87bd backlight inverter

Hey!

I also have a SAMSUNG LE52M87 LCD TV and I have the same
ANOYING BUZZ comming from ( I think ) backlight converter. - I am
almost 100% that its because of the backlight inverter while the sound shifts frequency when backlight is changed ( from 1 - 10 ), but the volume of the buzz stays the same. Only the tone changes. I have this TV for a year now and havent realy noticed until now, so I think it started buzzing recently, because I didnt hear it before ( and I got realy sensitive hearing :) ) ...

ITS DRIVING ME CRAZY ...

PLEASE post what happened when ( if ) you changed the inverter,
or what did you do to solve the problem ...

Many thanks in advance!

Any capacitor on the power regulator board might have bursted out. Check the power regulator board. Replace it as card basis.

Samsung ln40b550k1f screen flickers on and off


When the screen flickers on and off it usually comes from the power supply or backlight inverter being bad. For your TV, the backlight inverter and power supply unit are combined. As you can see in the picture attached it's the white part on the right side that has gone bad. You will need to replace that board. LN40B550K1F Samsung LCD TV Repair Guide

SCREEN FLICKERING


The power supply module in this tv is part number BN44-00341A,
Samsung's dealer info says to:
For BN44-00341B; cut and remove jumper JP852.
This jumper wire is located just below the part number stamp on the pc board, I've done several of these and it cures the problem.

Samsung picture flickers


Pull the back off the tv. Look at the power supply. Find jumper designated JP854 on power supply. Take a pair of wire snips and cut that jumper out of the circuit. Put the tv back together. That's it.

You might want to call Samsung with the model number as I remember seeing a notice for certain models that have this issue---a jumper plug needs in those sets to be removed that is located on the power board.

The screen flickers


The backlight inverter board may be going bad or the power supply problem. Look for bad capacitors.

Samsung 226bw visible flickers just after it is turned on


You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
