Re: Sony KDL26AF400 2 blinks

Okay well I had a bit of a "screw it" moment and I jumped the isolated Power_ON line of the power supply.

When I tried turning it on, the first press of the power button the green light comes on and off, a second press turns the TV on for around 8 seconds and I can see the BRAVIA logo on screen but rather dimly, i can also hear the speakers pop and the audio amp come on as well as a bit of static heard on the speakers. After this the tv goes off and gives 7 blinks.

From what I noticed and heard, the inverter seems...

Here's your picture of the boards, sorry it's kinda crappy.

No BL_ON, no ADIM, no PDIM. Not even for a second.

I thought I was close to what may have been a short but now I'm not sure. I was getting a reading of 10 ohms across a coupling cap and ground. I found that the source is IC7005 pin 13 which says Vout. The voltage branch is called D3.3V. Every part of this branch reads 10 ohms to ground but considering this is only 3.3V then that would only be around 300mA which may not constitute an actual short, 10 ohms is probably...

Oops, sorry about that. It's KDL26FA400.

I tried isolating the Power_ON line from the power supply and still don't get anything. What does that tell you? Bad MCU somewhere?

This is the board,

Re: Sony KDL26AF400 2 blinks

anyone? would love to get a second opinion on the diagnosis.

Hello everyone,

I'm trying to repair this TV which has stopped turning on and everytime you try to do so, I get two red blinks. I'm fairly experienced in electronics as well as troubleshooting, TV isn't what I normally repair (although I do have some past experience) so I could use a bit of your help.

I looked up the error code online and I got a few mixed results. Some tell me that this means some type of power supply issue unless the relay/power on signal never shows up, in which case it could be the main board. Others tell me that it's a b+ over current protection...

Hello everyone, newbie. Have a good amount of electronics and troubleshooting experience but since I don't do tv repairs anymore sometimes i need some re orientation.
