Re: Alba 32880hdf Flashing standby
I have a 17MB62-2.6 with fried processor but OK firmware chips. I can send you the dud board for postage cost, perhaps you can make some use of the flash chips.

Re: Alba 32880hdf Flashing standby
ahh,seen pic lol,try googling for a pin configuration,some you can short 2 pins,power tv on and remove shorts this reboots the eeprom,not on all thoughLeave a comment:

Re: Alba 32880hdf Flashing standby
only one i can see there is the 8 legged chip to the left of the yellow sticker,prob closet to the proccessor ,is that it ?,any part number,eeproms are normally 8 pin chipsLast edited by multimeter; 01-16-2014, 04:45 PM.Leave a comment:

Re: Alba 32880hdf Flashing standby
what EEPROM is on the main board?,maybee one that can be reset,using a pin to pin short,that might bring it backLeave a comment:

Re: Alba 32880hdf Flashing standby
well that went tits up, done that with the update file on the stick, the led stopped flashing and remained blue the pen drive had acitivity, let it sit there for 5 minutes after no activity powered off and now have no led, the xbox360 no longer sees the hdmi either
usb still gets activity and the led lights up briefly if i press buttons on the remote at power on
seems it now does need a new main board

Re: Alba 32880hdf Flashing standby
quote from the link
The flashing LED can indicate a short-circuit, so with the aid of the manual you need to check the voltage rails on the main board first. You will also get the same symptoms if the firmware is corrupted. I can send you the firmware I have for this model, which you shove on a USB stick, power down the TV (pull the plug), put the stick in the TV, hold "OK" on the remote, plug TV back in still holding OK down until LED responds, then let it do it's stuff and if successful the set will power up to the install screen after a minute or so.
so do you need to see the screen? not sureLeave a comment:

Re: Alba 32880hdf Flashing standby
It is possible, but I'm not sure how. I heard it's related to inserting USB, and pressing some buttons on touch panel.Leave a comment:

Re: Alba 32880hdf Flashing standby
ye i seen that too, judging from the post it seems he had access to the screen to update it etc whereas I don't
from reading you need to get to the service menu to do it, i'm guessing tom is talking about doing the update blind so to speakLast edited by anotherdude; 01-16-2014, 02:37 PM.Leave a comment:

im sure tom will be along to advise be good to know actually for future refrence.

Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On... -
Hi all,
Error – TV not powering on - with standby red –led flashing
Model- LEDTV – 39T3500

I have read through the Basic LCD TV and Monitor troubleshooting guides.
https://www.badcaps.net/forum/showthr...956#post305956, I am no ELEC engineer but can use a multi meter and soldering iron
In the meantime I could not see any damage to any caps on the cold side of the power board, so I have replaced all of them.
Unplugged the power connector on the board, I plugged the power cable in waited... -
As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
Obviously the same LVDS connector for the screen connection... -
TV standby light flash once after plug-in AC power. Then silent. No backlight, no LCD image on flash light test, no SPDIF light.
All PSU voltages to main looks good (12v, 20v (label says 18v but is 20), standby voltage) Probing main board shows what appears to be a DCDC converter (MSH6103A can't find datasheet) providing 5v, 3.3v and 1v. 5v present to the standby light power switch board.
These HiSense TVs appears to have lots of firmware corruptions that takes out the main board either through smartTV use or firmware update. Used main board...
