Re: 40" Sony LCD KDL-40EX500 Seconds to black (6 blinks)
To anyone looking for the Dim Control Wire, I have posted a photo of the wire I had cut which resolved the issue with my EX400 stuck in a power cycle loop and receiving 6 Blinks. Please note that the backlight will run at full brightness when this wire is cut. Good luck!Attached FilesComment

Re: 40" Sony LCD KDL-40EX500 Seconds to black (6 blinks)
Awesome thread, saved me hours of troubleshooting probably.
THANKS!
Removed DIM wire and it stays on.
Btw, the PWM frequency is 150 Hz and the duty cycle is stuck at 5% (350us positive pulse width).
Funny thing, while re-running the initial setup, the duty cycle increases to the currently adjusted backlight setting. Must be some firmware problem maybe. After the setup has finished it returns back to 5%.Comment

Re: 40" Sony LCD KDL-40EX500 Seconds to black (6 blinks)
hi
It too late to answer for this tv but i would like to get expert opinions
so check mytv.jpg kdl40ex500
1-If the tv is ok with cut dimmer wire why not try to put
a manual dimmer control 1v to 3v with a 1k pot or a small
regulator for low output impedance from the 5v or 12v.
for all the solutions with a tv (not this one) is it possible to do:
2-with bl-on cut put a jumper with 100 ohm between power-on and bl-on to force inverter board
3-with bl-err cut force a good condition err
thanks :-)Attached FilesComment

Re: 40" Sony LCD KDL-40EX500 Seconds to black (6 blinks)
Same issue. I pulled pin 14 from connector CN6402, labeled Dimmer. The Sony kdl-40ex501 came right up. No more 3 reboots; no more 6 blinks ... Awesome. Thx to tieny and budm. I had a great time trying to follow you both, and I understood enough to test the voltages on the board, and get to the solution. Are there any other downsides to disconnecting wire 14, besides dimmer functionality? Since this is part of the Protection system, what have I lost?Comment

I know this is like 10+ years on, but I just wanted to thank you folks for helping me save my beloved 15 year old TV from the landfill. While I'd still love to fix the dimmer, at least the TV is usable again and I couldn't have figured this out on my own so thanks a million!!Comment

I'm currently working on repairing a malfunctioning Sony TV model KD-65XE7005 with the mainboard 1-981-926-21. I would appreciate your assistance with this issue.
Upon powering on the TV, the Sony logo appears for approximately 3 seconds, after which the backlight remains lit, the screen remains black, and nothing else happens. The TV consumes around 55W initially and then drops to 35W. The indicator LED remains solid white. It doesn't respond to the remote control. When attempting to update the TV using a USB dongle, the dongle briefly flashes but nothing else happens.

Hi community! Germany calling
I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!
I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!... -
Hello,
I have problem with SONY 55X90J. After several check status is as below;
1. Running power board as stand alone:
TCON_12V =~ 12.6V
EVDD V On Max 24V= 19V.
2.Running power board with TCON as stand alone:
Effect as below, attched.
3. When bottom LVDS cable is disconnected no blinks, but of course no TCON 12V and EVDD.
"I'm almost sure it's a defective panel, but maybe someone has encountered a similar issue on their screen.
Best regards.... -
Hi everyone. First post on Badcaps!
I am trying to fix a Sony 940E from 2017 that either starts normally (and works perfectly until turned off) or goes straight to the 6 blinks error code without showing anything on the screen. It is frustrating to know that it can still work perfectly but is barely usable because of the difficulty starting it up. I am willing to try to short the BL_ERR but I would like to avoid that if possible. Does anyone have a view on this? Thanks a lot.... -
Hi everyone!
I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.
Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...
