Re: firmware real dissaster toshiba 55v5863dg
Hi, if I find it, come back and tell you here
Main board 17MB130S
Panel VES550QNYL-2D-N01
RT809H programmer
it is this card and how have post, I can put a kind link upload?
once if I have the file I put hereLast edited by toubia; 11-06-2021, 06:04 PM.Leave a comment:

Re: Sharp LC-60 DPS-162kp
R.J thank you for the diagram would see with rested head: =, precisely I base myself and look at the data of the stra6069h.
and a question what is the value (M) of the condo and resistance: mega 6 zero?Leave a comment:

Re: Sharp LC-60 DPS-162kp
circled in green, around the ic smps and yoyo I don't know how to say in English it is the number which dijoncti which goes up then goes down then goes up, that's itLast edited by toubia; 11-03-2021, 04:23 PM.Leave a comment:

Re: Sharp LC-60 DPS-162kp
hi, with a little delay here I tested last night with everything reassembled except r7002. still the same nothing no t7901 output no stby5v voltage.
by the way a few days ago I measured or it is twisted in green at the level of the ic 7903 side above the card and I had the voltage which made the yoyo between the t7901 pin 2 and on the diode d7905 followed by c7901 after c ' was normal on the other components and 15 v in below the transform the 2 cap and diodes, it was just before deciding to remove this diode to see and ic 7903.
now I say to...Last edited by toubia; 11-03-2021, 10:40 AM.Leave a comment:

Re: Sharp LC-60 DPS-162kp
hello, the stupid thing that I did not do is to test the 5vstby at the p / n terminal on the cold side after replacing the bd bridge.
the I must replaced:
r7902 51k.
r7002 2k.
c7907 47uf.
c7906 smd 47yf max.
d7950 I read 280 ohm and in diode mode 346 ohm 1 way.
i know if this is good?
and another question about the opto (2561b, gk210) or there is the line, period is the transistor or led side ?.
for me it is transistor why these 3 are mounted on the cold side of origins.
I have only one reading...Last edited by toubia; 11-01-2021, 11:34 AM.Leave a comment:

Re: Sharp LC-60 DPS-162kp
I put my negative everywhere on the hot side card, big transformer, departure of the negative by the bridge it's good,
the ic smps switch is the 7903, isn't it?
and what voltage should I get as it is as it just happened from 230v ac and 190v to 160v dc should I get the right reading with the right negative?Last edited by toubia; 10-31-2021, 05:42 PM.Leave a comment:

Re: Sharp LC-60 DPS-162kp
I would like to know where it comes from, where does this 5v stby come from, these good from the t7901 and resort well to the secondary cold side ?? if you can enlighten me
and thanks to the other members and budm for his help and his sharing.Last edited by toubia; 10-31-2021, 02:10 PM.Leave a comment:

Re: Sharp LC-60 DPS-162kp
I have everywhere 340vdc + - on the hot part, also remove some diodes and the opto, it is to surround in green also ic7903. also the small condo c7906 and now cannot read it nothing on the multimeter.
I have 340v everywhere on the ic7903 5-3gnd. 7,8-3gnd .1,2-gnd. pine 5-7.8. 7.8 -1.2.3.4.5
and voltage also on t7901:
1-2, 3-4 : 340v
I have a multimeter beast and a soldering iron, I am waiting for the ic 7903 from the neighboring country. I suspect the little one will turn into a short circuit from...Last edited by toubia; 10-31-2021, 02:07 PM.Leave a comment:

Sharp LC-60 DPS-162kp
Hello everyone ,
I am just particular with a small base in electricity, and do not know anything in electronics. it's my first tv that I open it's for someone I know,
So received this tv broken during the day before I think, after opening finds open fuse, c7816 exploded
so I replace c7816 check the fuses resistors restore the power supply again the fuse open.
so I remove R7900, C7816, Z7001, R7002 still short, after Q7801 device. so it was the bridge bd 7001 the problem after more short to the ignition.
but still no 5v stby or other voltage, I dismantled... -
Re: New Members - please post your introductions here
hello, me it is toubia mo English is bad, am just an amateur who hack from time to time. I have a base in high school electricity otherwise I have already opened a game console, pc, electrical appliance in general and tried your repairs. the currently small device engine.
I am also at the time in your console and sat forums.
here thank you for welcoming me to your great forum.Leave a comment:
