Re: Samsung LN40B530P7N
More likely to have bad GAMMA Voltage ref IC AS19 (U7), same common failure as AS15 series IC.
You can take GAMMA DC Voltage on the test point 1~17 (Top middle section of the board) and report each reading.
Your T-CON PCBA # is 35-D026047

Re: Samsung LN40B530P7N
I guess the AS19s are starting to be more of an issue too. This problem is amazingly widespread.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung LN40B530P7N
I also currently have an AS19-H1G I believe is faulty. I believe its time to stock up on them also.Comment

Re: Samsung LN40B530P7N
I wonder if AS19 is based on the AS15 design and manufacturing.Never stop learning

hi
i have a samsung lcd tv
it powers on with sound and backlight but no picture
all voltages from PS are good 12v 3.3v and 5v
whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v
i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue
no 12v at the tcon fuse
i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse
the odds of having 2... -
This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... -
Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...
