Im working on a Hitachi P60x901, picked tv up with no power. Replaced a couple large caps on power supply. Now tv seems to be powering up, voltages are good at ps. But the screen is not priming? No flashing lights on led, goes from red to blue for about 20 seconds then to orange. From manual I have read that orange indicates no r/c,a/v signal. But shouldnt the screen at least prime first?

Hello Everyone!
I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died....06-28-2025, 02:57 PM -
When i fully shut off mac, orange light goes off and wont react to power button. I have difficult time resetting with combination "shift+control+option and power button", because it rarely works (reason unknown), when i manage to get orange light and then press power button macbook wont turn on and orange light goes off. When i hold combination with power button it turns on, and works fine if put it to sleep mode.
Works with battery and charges, but when i shut off i get this problem.
It had liquid spill. Board has no corrosion, keyboard is working, power button... -

Hi,
I have 2 Elitedesk 800 G4 which have stopped working after a BIOS Update. It was doing the updates and instead of rebooting automatically it just stayed off and I was left with an orange LED being on behind the mainboard and no reaction at all when I hit the power button, it seems to be completely dead.
Removing the battery, pressing and holding the yellow button on the MB didn't do anything either.
Others have updated fine without any such issues.
When googling I've found other people having the same issue with the orange LED being on and the PC also...10-29-2024, 04:27 AM -
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?
