Hi, when turning on the TV, screen flashes (no image). Red light blinks 23 times, which means fan protection error. The small 50mm fan over the power supply was seized. I replaced it with a fan that had similar ratings. still the same thing, 23 blinks. Any ideas?

Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem -

Re: Sony KE-P42XS1 23 blinks
I don't have good lighting here atm, so can't post very good pictures. Here are a few anyway. The last pic has nothing to do with the problem, it is the TV's backpanel - apparently it is a smokers ex-TV.
Yes. I just found out that if I bridge the sense line and ground, the TV works. Not sure why it doesn't like the new fan, it's 3500rpm while the old was 3300rpm, so that shouldn't be the problem... It is a Fractal Design Silent Series R2 50mm fanComment

Re: Sony KE-P42XS1 23 blinks
I connected the sense line and ground line from the fan together for now.
New problem: sparkles (or what is this problem usully called? last picture)
It is especially noticeable on faces.
I also took some new pictures, apparently my phone takes much better pictures than my camera...
I'm kinda new to plasmas, so I'm not sure if I can fix this problem by adjusting pots?
I tried to lower the VS voltage a bit (2 volts), but that made it worse: it didn't change the problem you see in the last picture, but added red sparkles all over the screen.
The VS measures 89 volts (should be 87.9V according to the label) and VA measures 65 volts (63.2V on the label)Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: Sony KE-P42XS1 23 blinks
I seem to remember reading something from Alastair on this forum about sparklies on these old Fujitsu-Hitachi panels (FHP) being a design defect, with no fix available.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi there,
I see a couple of posts related to the troubleshooting of similar TV. The one I have is acting slightly differently and I'd love your help.
So it has the 5 blinks. Previous owner got a TCON, no luck. Got a new Main board (though he didn't do the USB firmware update), again, no improvements.
I see 2 posts that are relevant:

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,
I'm working on a HP Victus that is not turning on. When power button pressed it only blinks 3 times with charging led. I have checked input mosfets and they are fine. Also all coils are fine too. Battery was empty but I charged it with my lab PSU and laptop started on batery but is not charging. When battery is disconected and only PSU connected it takes 0 current and not starting. What can be the reason? -
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...
