KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help.

Hi all, I’ve got a problem I hope someone can help me fixi.
I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...01-11-2025, 03:18 PM -
Samsung UE55JU6800K with no image on screen.
I have had this TV many years without fault, however aprox 6 months ago I fitted a new set of backlights as some of the lens caps had fallen off.
Was working fine, until 3 days ago, when watching TV the screen just went blank (still illuminated)
I turned the TV off and left it around 12 hours, and when turned it on again it seemed to work perfectly again. After around 45 mins the screen went blank again.
Left it off overnight and turned it on, and the Smart TV logo came on as normal, then screen went blank.

Thanks in advance... -
Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.
Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing.
O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0.

Thanks in advance. Here is the log in Colibri :
