I came across a Sony SDM-HX73 for free, knowing it was broken. The monitor will power on, and stay on, but the picture only appears for a second (tinted red as well), and then the screen goes black. I've visually inspected the power supply, and nothing seems to be amiss, just some slight discoloration of hot spots. Any ideas what might be happening?

Re: Sony SDM-HX73 issue
Is it red or more of a pinkish color?
If it's pink, you may have dead lamps in the LCD panel itself which are making the inverter shut down.
Open it up and give us some nice clear pics of the internals. -

Hi, I'm hoping someone can help me with this issue before I give up on this TV.
In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.
Here is a rundown of the symptoms and the steps I have taken to troubleshoot:
I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes... -
Hi everyone,
I'm troubleshooting a power supply issue with a Sony SLV-E780 VCR. The device clicks repeatedly but doesn't power up completely. I've already replaced five capacitors, but the problem persists.
Here's a video link https://photos.app.goo.gl/3Xki6yvCLn67gLX78 showcasing the sound. Based on your experience, could this be due to a transformer, diode, or another component? Any guidance on what to test or replace next would be greatly appreciated.
Thanks in advance for your help! -
The monitor is old yes but occasionally used (perhaps about 1 ~2 hours usage per day on average)
one time i turned the pc on and noticed this issue
what could it be?
nothing wrong is seen when it is off, also the issue is not there on a green screen!
when watching movies it is hard to detect unless in black screen/large shadows
please check the images, thanks...04-14-2024, 10:06 AM -
Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,... -
For anyone interested just repaired this Sony Main board TV that had a 2 blink error code, the chassis is a RB2G which is common to quite a few different Sony models. The Ceramic 10uF 25V X7R 1206 capacitor C9114 was shorted which took the smd 2A 0603 fuse out F9101. This was powering the Buck converter TPS54332 which caused no 5V output from it.
See the attached picture of the locations of both components. I also attach the best service manual I found for this board for anyone else in a similar position of trying to repair this main board. It's not specific to the TV model however it gives...01-08-2024, 05:56 AM
