I saw people have posted about this problem but i did not want to ask question when they are looking for answers on there post. I am having a issue with my model is the 50pk750. I ordered the repair kit on the tv. Replaced about 8 different pieces, the tv worked for about 5 days or so then stopped working. I think the repair kit they sent me was wrong, due to the pk750 model has 3 big white startup resistors and the kit only brought 2. What i did notice was if i left the back of the tv off. The tv would not shut down at all, had it running for 2 days straight. When i put the back on i would say in 10 minutes or so the tv would shut down. Blue light in corner would appear as if turning on, but then would make clicking noise then shut down. I was wondering if the repair kit should have brought 3 white resistors? Or do you thinking something else is wrong?

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have a floodlight-security camera that recently died on me.
its hardwired to 115v po115v outlet. One evening it simply died. After some troubleshooting (ensuring it had power and ensuring the electronics were actually functional by supplying 5v via usb port) i realized the power supply must be the issue. The supply was noticably warm to the touch even though it was not powering anything.
Trying to understand what i was up against i went looking for others with similar issues and anyone who might have attempted a repair. While a few ppl have had the... -

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!
