I have a Polaroid Model FLM-3732, the tv does not turn on, I checked the screen with a flashlight and it is totally dead. I remove the t-con to see if that helps but it did not. The power bottom works to turn the standby light on but it does not turn it off, it remains on. I check the standby voltage and I have 4 volts instead of the 5 volts, would that be the problem, and also, instead of having 12 volts on one cable out of the PSU it reads only 10.7 volts, other voltages are normal, inverter board has voltage as it does the tcon board.

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... -
A) TV initially dead
B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
C) Was able to perform a Reset from Settings menu and completed out of box configuration.
D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical... -

Hi all , thanks for having me & I think this has been asked before but my case seems a bit odd.
I have a MacBook Pro , board 820-2915a and it turns on , chimes etc etc , keyboard lights up, fans spins , can turn caps lock on/off but screen is dead.
Iv tried the resets , shine torch through back logo , nothing , it seems the screen has no power. If I plug charger , it charges but if I disconnect battery it displays green light but won't turn on. Iv tried screen on with another board & it works & seems I'm not getting any voltage at pin 2 , next to ground pin .
is this... -
Hi guys
I'm trying to fix this laptop screen
Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!
OK so I have the original screen which works but has lines across the bottom quarter of the screen
I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...
