    Hitachi 27 (1991) so many fishy badcaps!

    And rank.

    Nich and Rubyicons; TWSS and SME series, few big ones and about 40 little total ones; 4.7uF, mostly 10uF, some 47uF capacitors. Had to clean out the ooze too.

    Is that because of bad bung seal around the leads? And why did some use electrolyte that is very rank smelling like a ROTTING fish? Not to mention that smell get worse when desoldering them out. Make you feel like need to get repirator mask.

    Reason I did this looong recap job session is CRT is still excellent and high end model: has bass speaker box on top, S-Video and few inputs and one output with choice of internal speakers or external speaker outputs (unampified and ampified). Now excellent pic and audio. And to pocket the pay for the work. I work for TV shop.

    Cheers, Wizard

    I still have a Hitachi from 1975 sitting around here that used to be my grandma's. You'd think it was made yesterday, the picture is that bright and vivid on it. I've had to replace a few capacitors on it, but it's worth replacing a few caps to keep a good Hitachi in service

      Hitachi 40HYC42
      by dragometin
      TV Model: Hitachi 40HYC42
      Power Supply: 17IPS71
      MainBoard: 17MB95M
      Panel: VES400UNDS-2D-NO3

      When the set came in it was dead. Fuse was open primary side and the power mosfet was shorted. So I ordered a new power supply. Now it turns on, only displays "Hitachi" and then power off red and blue led flashing.

      I had to modify the 0ohm resistors in the led backlight of the new PS like the original power supply.
      Is there any variants on 17IPS71 power supply's?

      UART output pins 10 and 12 on scart connector:

      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...

      Hitachi V19B01922 Channel Tune problem
      by dicky96
      Hi Guys
      I have a customer who has two Hitachi TVs in his bar, one is the model in the thread title and the other is a larger screen but has the same setup menu

      He also has an LG TV, so three screens in the bar

      I installed three Satlink ST-6503 DVB-T Modulators
      This model https://www.aliexpress.com/item/32916553905.html

      These connect to three satellite receivers via HDMI cables and then connect to a 4 way RF Amp that connects to the TVs on aerial cable. There is no incoming terrestrial antenna. I set the channel ID on the modulators to...

      Hitachi Power Supply Unit Interchangeability
      by navagator
      I have a Hitachi 57F710E rear projection set with a bad power supply board. I've tried to fix it with help from this forum as well as another one, but without success. Today I found a Hitachi rear projection set for sale on Facebook that looked just like mine. After contacting the seller I found out it was a 51F510. According to the service manuals my set uses a HA01312, POWER UNIT DP4X-DM_24W and the 51F510 uses a HA01313, U901, POWER UNIT DP4X_24W.

      Does anyone know if these 2 power supply boards are interchangeable?

      Thanks.
