Re: Sony bravis kdl-52lx900 t-con board
Yes, but im not sure the seller cause i cant pay by paypal, is it the tv panel or tcon board broken? If i buy the tcon but the panel broken it will spent more money then
Would you recommend for the used price of this tv if in working condition? I want safe this tv, but i dunno know how much should i spent for it or is it worth if spent more $500 for this tv?...

Re: Sony bravis kdl-52lx900 t-con board
now I put the ribbon cable back in, and the amber and green light still flashing, before, I soldered the connector pin to f100, and smoke coming out from the chip of fet908, how do i check the fet908 is still work? and then I tried solder back the fuse again with cable not only thin wire, now the tv gave me amber and green light flashing with my usb light flashing but still dark screen so I turn it off cause I went to work, the voltage of vcc12v is steady now with 12v, so what does it mean?

Re: Sony bravis kdl-52lx900 t-con board
You mean cable that connect to mainboard? Or the four ribbon cable that connect lcd panel?
Anyway, just let you know that i had change the mainboard before.
This morning i just try to solder wire from the connector to f100, but when i connect it, i just burn out the chip of fet908, now is it fixable? Try to find the part of tcon, but out of stock, dunno what to do now, hopeless...

Re: Sony bravis kdl-52lx900 t-con board
On my power supply side when i turn on there is no voltage but when the tv wanna shut itselft off and then there is vcc11.1v, cause when i connect the tcon to power supply, my tv start turn on and off with 5 second duration,
Do you mean the volt of tcon fuse? If yes, then, i got no/zero in my multimeter but when test in continuity there is no beep.
Thanks...Last edited by handycap; 02-03-2014, 06:06 AM.

Sony bravis kdl-52lx900 t-con board
Hi, i have sony kdl-52lx900 that flashing 5 times, i just wanna ask about the fuse of t-con board.
Is this the fuse, the little black one?[ATTACH]79925[/ATTACH]
If yes, i tested it with multimeter, and there is no open line or no beep on my multimeter, could be this problem that make my sony tv blink 5 times? You guys know how to jump the fuse? Start from where should i solder?
Before i fix my power supply fuse with soldering a wire, that fuse connect vcc12v.
ThanksHi, i have sony kdl-52lx900 that flashing 5 times, i just wanna ask about...

Re: sony kdl-52lx900 3 blink problem
I did heat gun for my ps3 mainboard and it work, so I tried do it again to my sony tv.
the meaning of the 3 code is Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
And also I did test to the 3 transistor near the dc connector, it look in multimeter 0.302, 0.200, 0.03.
Is it possible problem from the transistor?
I wish not the mainboard broken cause I couldnt...

I tested the dc voltage and only 3.3 voltage is on, other like 12 voltage and 12 voltage to tcon is zero on multimeter, sorry this is my 1st time used the multimeter.
Do you guys think it can be fix by replace transitor, diode, capacitor on power supply?
And what should I check in power supply using multimeter?
Thanks guysRe: sony kdl-52lx900 3 blink problem
