    ye everything seems fine, tv powers up and picture is displayed (smashed but) so main board inverter, t-con for £10 saved me £20 from the off anyway so

    funny thing is the toshiba was bought from the same person i bought the hitachi from, if only they'd of took the backs off the pair of them

      Re: Hitachi 32hk04u

      ok well that didn't go as planned

      plugged it all in and getting the red standby light then the blue flashing alternating between the two, when I press the power button it does flash purple (the red and blue led together) and theres a little whine from the psu

      seems these 17pw25-4 psu's are different

      caps are placed differently and the 2 red things on the original psu only have 1 present on this one

      any suggestions would switching the parts round solve this to match the original?

        Check if your bad original PW25-4 has a little jumper fitted to the bottom of it near the main board power connector. IIRC it's S815. If it does copy that across to the other board. If it doesn't remove it.

        That jumper being in the wrong position will cause a flash of death.

        The caps have nothing to do with it.

                  Yeah it would be REALLY great if you could I've got one that's completely f**ked and I cannot figure it out for the life of me. Not blowing fuses any more, but no output voltages.

                    your probs like me i try my best not to board swop i like a challege and gain experience in component repairs and fault finding but when parts cost more than a working board why not swop them. the old board is always handy for parts i guess i only do this as a hobby to get a better tv for myself plus if i sell any it keeps my car on the road as im unemployed at present.

                      I don't like giving in but sometimes I have to accept reality and maybe I'll get that board.

                        would this fried board be of any use to you just pay the postage?

                          I've got two other fried boards here. Such a common fault. You might as well keep it for spares.
                          I appreciate the help with the readings.

                              tom my apologies but I won't be able to get the readings for you, had someone wanting to collect first thing this morning for my asking price and couldn't say no

                              I am sorry about this, just i've waited before and had to lower prices etc so when I get my asking I have to accept

                                          im sure with time you will also be able to fix these 17pw25-4 as well i suppose some blow up worse than others? tom is there any sets gauranteed to have these psus in as im always being offered free smashed screen sets just dont pick to many up.

                                            I ask for help with a problem with a Hitachi 32HE4500 TV that no longer turns on, do I need the firmware for the Vestel 17MB211S motherboard, panel code VES315UNVL-2D-N11? I hope someone can have it to reprogram eprom. Thank you

                                            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:

                                            Code:
                                            12:24:04.595
                                            ...

                                            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.

                                            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.
