Re: Alba 32880hdf Flashing standby
I'll give flashing the NAND a try. The usb_auto_update.txt shows that the NAND is flashed with only 16Mb (mb62_en.bin) where as the NAND is 64Mb correct?
From what I can see the actual FW occupies the first 16Mb and the rest is used for filesystem (I could be wrong). When updating by USB only parts of the NAND is flashed so this to me seems like the issue.
I'm not 100% clear on what all the commands in the usb_auto_update.txt mean, but from looking at them from different FW downloads I can see certain options are enabled/disabled....

Re: Alba 32880hdf Flashing standby
Yes I've already downloaded the firmware for this LCD, Toshiba only provide 2 files in the archive but like you said all the mboot.bin files are generic
(I even opened & compared several using HXD)
This Toshiba will happily install FW all day long but only shows a pixelated screen (see pic). I've tried several FW and I either get:
Long blinking LED - bad FW update
TV powers up but displays black screen (backlight is working)
or
TV powers up but displays pixelated screen

Toshiba 32BV702b FW issues
I recently got hold of a Toshiba 32BV702B from a friend who was going to throw this one away. I took it off him to use as a spare PC monitor.
Foolishly I updated the FW via USB and now I'm afraid the TV has issues...
The TV powers on as normal but the screen is very grainy/dark, I cannot make out any text in the back ground.
The touch panel registers button presses but no longer switches channel/volume etc.
(I can take & upload a pic if needed)
I've downloaded the FW for this model from Toshiba (v6.8c) and installed via the... -
Re: sony kdl-32l5000 nice picture after 10m goes dark no picture
Hi there, since NO-ONE can give you an educated answer, I'll help you out.
You will need to replace BOTH backlight Inverter boards (if your model has 2)
Generally when one goes, the other one won't be far from dying. The backlight shutting down is due to the inverter switching itself off (overcurrent/overvoltage protection). The transformers on the inverter boards break down with time & temp and can give problems such as flickering, NO backlight, or a few seconds then turning off.

Sony KE-32TS2E - Dark screen / Green Haze
My problem is my Sony KE-32TS2E Plasma tv. Was given to me by a friend who's just upgraded to a 42" lcd. Tv has worked with no probs for a number of years.
Anyways, I have the tv now. When I turn it on, the picture displays as normal for about 1 second then fades out to dark/greyish with green hue, then 'click' and the tv turns off. I could hear the sound no probs for the split second it was on. After checking the service manual, I've set about trying to repair it.
I purchased a pair of boards from ebay (X & Y sustain boards) as they were the first 2 suspect... -
HP Compaq 6735S - No power / No charge
Hey all! Firstly, this site is amazing! I've been looking for something like this for a while. I hope I can input some of my knowledge to others as I have quite a bit of experience with laptop motherboards.
I've been working for a PC shop for over 12 months now repairing laptops & consoles at component level so I've learnt quite a bit.
I've been trying to isolate a fault on this laptop board for some time now.
The laptop in question is:
HP/Compaq 6735S
Original fault was a dry joint on the DC socket. I've been trying to get...
