I inherited this lcd tv and I know they are out of business but I thought I would give it a shot . When plugged in it immediately gets to come on, the blue olevia light comes on and then goes off and I get a blue screen for about 5 seconds then back to a black screen and the blue olevia light flickers then the blue screen comes on again and there is no sound .It repeats this over and over and the buttons have no control and I have to unplug it. I took the back off and plugged it back in and on the power supply there is a buzzing and clicking sound that coincide with the blue screen coming on then the click and the blue screen shuts off. The sound is coming from a transformer?? That is wrapped in yellow tape. I unplugged the inverters and get the same buzzing and a click then I unplugged the t-conn board also and still the buzzing and click. I'm not sure how to test the transformer but could something on the control board be causing it to overload and trip off and on? I hate to throw this out cause the lc370w01 panel is in other 37's and I believe its good. I will post pics in a bit.

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hello,
on this laptop acer aspire v571p the led of the power indicator blinks blue for periods of 1s lighted and 3s off after switch on and this indefinitely.
i tried the hard reset, cmos reset, changing the ram without results.
in order to reach the cmos battery i disassembled the laptop and did several mesures with my multimeter.
The 19v, 5v, 3v are well established after the chip 5v-3v. the following signals : 3d3v_aux_kbc (which supplies the sio chip) and 3d3_s5 are well established also.

Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -

Hi.
I have the Samsung TV Model: UE65TU7000KXXU VER:02/UTU7000 which has developed the following issue: blue screen while the sound it's still working. This happened after the screen developed some horizontal lines at first and then the next day suddenly turned into blue background. the screen was not damaged or anything. I can't access the menu. I have taken the tv to a local tech to have a look and he said that he thinks that it might be the pcb board as the back-lights are working and the sound aswell . I was hoping maybe you can guide me if I should buy the pcb board or not? Thanks
