Sony bravis kdl-52lx900 t-con board

[handycap]

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?

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.


Thanks

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

what happens if you remove the top ribbon cables fron the tcon and only have the bottom one in does it still power off

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

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?

Most solid state device rely on smoke to operate, once you let the smoke out they no longer function.

The tv now, with amber and green light flashing, is that my panel faulty? What does it mean if amber and green light flashing??

It is possible either panel or t-con is bad. The fuse blew for a reason. I doubt this TV has a specific code for bad panel. Green-yellow sounds like it is boot looping (turning on t-con power only to have that shut down PSU, then restarting the process.)

Can it solder a jumper from the fuse to somewhere in tcon board??

Re: Sony bravis kdl-52lx900 t-con board

Given the MOSFET was destroyed previously I would NOT recommend that. You would only cause more damage.

Sorry, what is mosfet? I dunno what should i do now, either selling as part or buy the tcon board, but the tcon out of stock... If you have condition like me, what should you do? I already spent for the mainboard..

Re: Sony bravis kdl-52lx900 t-con board

MOSFET=that device that burned.

Don't know what to suggest, really; you might have to hold out for a t-con to appear or see if you can find a repair service.

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?
