[Solved] Toshiba TD-H49363G Backlight Issue: Red LED, Green Blinking, 17MB110P, 17IPS12 - NAND or SPI?

After connecting to the network, the backlight immediately turns on the red LED st-by lights and the green one blinks for several seconds. Then it turns off to st-by but it can be turned on by the remote control, i.e. it only turns on. Similarly, the TV can be turned off to st-by with the remote control. Anyway, it goes to st-by automatically after a few minutes (probably no signal). Apparently, it was similar earlier, but for a while (a week) the TV turned on.
Probably corrupted software / memory. The only question is whether NAND or SPI?
Main board is 17MB110P power supply 17IPS12.
Maybe it is possible to upload the software from Pena? I had a Sharp to which I had to upload soft pena and Vestel on a regular basis every few months.

There is a "boot" in SPI and as you write:

So it "boots", so the second option remains ...
This fault description is terribly "hazy" what are you guys out there this saturday night?

There is one more possibility and probably the most probable one ... Slingshot flies into balls ...

After a relatively light heating of the processor and the surrounding area, it started ... The question is for how long, therefore, I will do a reflow as a preventive measure.

Reflow unfortunately beat the record to the end. I also ordered another one from Toshiba. Yes, it even took off with the Toshiba logo, but with the image upside down and like in a thermal camera. So a different matrix. In addition, the original remote control did not work, but the original one from the old Toshiba worked. After consulting with the seller, I soldered the NAND memory from the old original disc. The TV does not move, only the green LED is red blinking. After returning to the original NAND from this album, the effect is as at the beginning. It only turns on the backlight and reacts to turn it on, turn it off from the remote control. A slight heating of the disc and, of course, a bad image starts up and upside down. strange that there was a fault like in the old record. Unless, while heating the disc, I also slightly warmed up the power supply ...
Application:
The 17MB110P NAND memory is paired with the processor .
Since getting a plate for this matrix will be a miracle, the question of the service mode to change the matrix will be a miracle. And since there will be another pilot, it is difficult ...

Unfortunately, there is not much that can be done in ordinary MS.

Maybe after I?C, having the right software, something could be done? Once upon a time I made an interface on Max232. Original also available.

The ordered disc was reprogrammed in a familiar website for the correct matrix, but the problems remained. Then there was a bad picture with a good logo and not upside down anymore. I gave up the topic with considerable losses
