    Hitachi 50" Plasma Buffer board question

    Im going to attempt to repair this sdr d buffer off a Hitachi Plasma Im working. I have already verified the tv works with the board out of circuit. I am not finding and pin holes in any of the 8 ic's on the board. My question is how to I test which ic is bad? There is only 3 ribbon connections and 8 ics. I would understand there were 4 connections >2 ic's per connection.

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          Help finding the correct model of a T-Con board on my Hitachi TV
          by sotodefonk
          Hi, I have a Hitachi tv model L47V651, there is no image, but sound and backlights turn on, so I believe the issue is the tcon board.

          I opened the tv to access the board and took the shared pictures of the T-Con board.

          I saw a video from shopjimmy on how to detect the model number on tcon boards, but this doesn't have a sticker like how that video showed all boards.

          I searched the P/N number and got results with the same marking name and P/N my board has but they list other specific tv models like Vizio and Philips brand but not Hitachi.

          Inspecting...

          Hi everyone!
          I happened several times, in the search for help from the web, to consult this very interesting forum.
          So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

          Having said that I come to the gist of my post on the forum as the title suggests.
          For my passion for technology I'm now collecting several...
