Was that with power connected?

No, no power was connected just using my meter for diode test.Comment

Re: Sharp Aquos LC-60LE633U won't turn on, no lights
Sometimes it can be hard to test in circuit and get a reliable result. Anyway, I'm pretty sure the diode is OK. The standby supply wouldn't work if it were shorted.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Does not turn on, lights 3 of the 4 LEDs and turns off and stays like this, presses the power and repeats.
I saw that the room LED lights up only when the screen is connected, so quiet.
We have all the power supplies, even processor, 1.8V
One thing I found strange, it has a very low resistance in the Vcore is giving 1 Ohm , work with notes and such, I know that this is normal in some processors but with this resistance only take video card so found it strange.
I suspect that there may be some leak in the processor.
Anyway, when I press the power, it... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display... -
Greetings!
Thank you in advance for your understanding, I am writing to you through a translator.
A Harman Kardon AVR171S amplifier was given.
The history of the machine is as follows:
It was faulty when I bought it, I want to fix it.
I replaced the HDMI switch and one of the DAC ICs in it.
After that it worked without a problem.
I watched a movie using the amplifier, and at the end the amplifier got really hot.
The cooling was faulty, I will fix this later.
I switched it to standby mode, waited for... -
Sharp lc-55p6000u won't turn on. The standby light is on but nothing happens when the power button on the tv or remote is pushed. I'm thinking this is a main board issue but they are expensive. I was wondering if anybody could tell me how to repair the main board I have. There is a repair service on Ebay but they're also expensive. Since there's a repair service for this main board I was hoping somebody could help me with the repair. The main board part number is 221999. Thanks!!...

Hello!
I'm a few days old into this TV screens repair universe so please bear with me.
Recently, and all of a sudden my 40” 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but I’m shore this is not an OLED.
- I did the classic unplug and hold power button to discharge the caps but it didn't help.
- I did a factory reset as well...
