Had a model UN60EH6000 that was displaying the same symptoms and had the same voltage drops on the t-con board. Ordered a BN95-00628 chip from ebay and a cheap hot air station, and voila! The TV works great :D Thank you SO much for this great informative tutorial. This got me into SMD soldering :)

I've seen this model come in a lot and it's usually the t-con board. It has a high failure rate and I suggest if you cannot replace the chip to use T-Con part # BN95-00944C instead as a substitute. It has a much lower failure rate and looks great after replacement. Great job NorCal
@dongraves9944 Жыл бұрын
Bruce, I've seen this part BN95-00944C sold as a replacement for BN95-00628, BUT with the note that it is "modified" to work. Did you need to modify it in any way? Thanks.

Much appreciate the video! Might you have a circuit schematic for this board BN95-00628C but also seems to be a common issue (no video display) as my problem seems to extend to blown main fuse @ F301, diode OPEN @ 2.5 M ohms (forward bias), O/L reverse. It also seems capacitors at least the primary common capacitors at C7114, and C7122 unfortunately I can't seem to find a schematic for the board. Thanks again for your great videos!

I have a LG 43UF770V and it has no picture, no sound, but the backlights turn on. I replaced the T-Con board but, didin't change the result. I then baked the motherboard (or main board) for 11 min for a reflow but, that also didn't change much. Before I did all that I noticed that there were some negative voltage readings on the right hand side of the T-Con board and wondered if it was normal to have the ground lead on the chassis but have positive readings on the left but, negative readings on the right (on the T-Con Board). I did not reverse the polarity.

Hi..i got my bn95-00944b board in today and works great now"...this board is a better alternative to bn95-00628c however the board is diff layout and the matal cover interferes with a board component..so i just put elec tape on the cover to buffer it from the component....tv works great now....if u get chance could you look up bn95-00944b and let me know which components i should put a heat sink material on top?

Hello, I subscribe to your channel and I have watched several of your videos. I am 58 years old and I have learned a lot from them. I have a question that I would like to share, seeking a solution. I have a SAMSUNG TV model UN49KU6300G and only when I turn on the TV so that the sound of it goes out in the Home teacher (SONY model MHC-RV9900 old) only a single sound hum sounds that it seems that it will blow up the loudspeakers. Detail: Only happens when I tune to local TV, NETFLIX. Already to play audio of the XBOX ONE S and TV to CABLE the problem does not happen. ps: I am using optic output from tv to a converter with RCA output since my device only has this type of input. Can you help me? I'm grateful for now. ps2: Sorry for posting this question in this video. William.

I have tested my voltages at the points you have mentioned on the video - I do have my 12.6v at the large coil (6R8 1242) but no voltage at the coil above it and the two caps 0 volts. Not sure where to go with this if I have the same failure (power voltage regulator) as you did. If you could comment that would be great! Thank you in advance.

@norcal7153 жыл бұрын
Is it the backlight pulsing/flickering? do you have the back off of the set? can you see the backlight from behind? Look at the backlight with the back off, if it is dimming/flickering then most likely you have a failing LED/LEDs. If it is then you should replace all the strips as a unit for reliability.
