Re: TOSHIBA 40L3453DB red-green blinking light

This is what i have, is it of any use for anything nowadays?

I will buy the
CH341A 24 25 Series kit

yes of course it did but need software interface to do this job.

yes CH341A more easy specially with clip also it can be used as programmer and serial USB to TTL too for tracing log, also you can use it afuture to program mini Arduino too with mini OLED (1$ panel ) .. it make more fun and good start to learning somethings new.

Re: TOSHIBA 40L3453DB red-green blinking light

I will buy the programmer and learn as it gives me something to do, i will start to read up about it while i wait for it to come and If it don't work i can always buy a mainboard

I still have a CY7C68013A Mini board which i used many years ago to bring VU+ clone sat boxes back to life, only used in 2 times and its been gathering dust in the draw ever since as they put paid to that way of watching P*rate tv

Re: TOSHIBA 40L3453DB red-green blinking light

the cheaper one to you include the clip and no extra fee for shipment..
for example

you need to consider 2 option
1- you start to repair it your self and this mainboards will be good candidate to learn with programming .. or

2- easy way you buy one used mainboards with 10 more extra as same to yours or where you can upgrade yours Toshiba model with one had SAT tuner if you like... all ab to you

Re: TOSHIBA 40L3453DB red-green blinking light

the 2 file attached need to flash them direct to the U10, by using cheap CH341A programmer adapter and One Clip for 8 pins.

the mega file you can do it as you did before by because no response from RC so need to use the side panel..

Could you recommend which one to get as there are a few different ones on ebay if you don't mind

Re: TOSHIBA 40L3453DB red-green blinking light

yes this one 25L606E, the other NO no need. you need to reprogram it because its now erased or corrupted when you did the flash so tv doesn't boot

i am putting here dumps for this 17mb95 with vestel panel.. could be help and make it booting again... and also one complete firmware which its include the file of this chip need to try too by using the side panel key of the tv

Note. if any other users have dump please share too to this threat.

Re: TOSHIBA 40L3453DB red-green blinking light

look under the cover of CI module if you find it or the downside of the boards .. and tell me under the 17mb95 you have another No

Re: TOSHIBA 40L3453DB red-green blinking light

I found U20 but there is no chip on it plus it has more than 8 pads were a chip would be soldered on there

I managed to get what was on chip U5
UTC RET8 (I think its an 8)
LR18120MB
12 01

there are no other chips with 8 legs on the board anywhere

Re: TOSHIBA 40L3453DB red-green blinking light

check again it should had label with 25L1606 or some things ells after L

[Fergal22]

Re: TOSHIBA 40L3453DB red-green blinking light

There is no u10, there is a U9 with this on it

RT7240A
GSPICE38

There is another 8 leg chip by it (U5) but its very hard to make out what it says on it

Re: TOSHIBA 40L3453DB red-green blinking light

try the first link to download and play it..

Hi, I tried the first link firmware a few times and nothing happens, no lights, nothing

I have added close up pictures of some of the chips in case that helps
sorry never seen you last post i will do that now

[Diah]

Re: TOSHIBA 40L3453DB red-green blinking light

also look closely on the mainboards... you will have ic chip with 8 pins (SPI FLASH) with label No 25 could you focused photo on it or write its full label over here

EDIT: should be U10
