Re: Toshiba LED TV, blank screen

Okay. I soldered a 220 kohm resistor from pin 13 to ground. Powered it on, got the Toshiba logo, "no signal" screen, went to menu just before it blacked out. Here's a picture of the resistor soldered to the board, the replacement I bought from China. I'm also posting a picture of the original board next to the replacement so you can see how different they are. It worked great for a couple weeks, though. It's worth noting that when I plugged it in after adding the resistor the plug sparked when I pushed it into the outlet. I'm beginning...

Re: Toshiba LED TV, blank screen


Hey, Bud. I'd like to try your resistor solution. Could you walk me through it? I've checked out the pics you posted to photo bucket but I don't see exactly where you added the resistor. I'd really appreciate any advice you can give me. As you can see from my most recent post, I've put too much work into this project to just give up.
Thanks
Tristan...

Re: Toshiba LED TV, blank screen

Hello all. I've been reading this thread for about a year. I picked up a Toshiba 46L5200U1 from work. My employer purchased it to use as a display for a Rolex ad running on repeat ad nauseum (I'm a jeweler at a high-end jewelry store). It burned out after 18 months. The Toshiba logo appeared in red after powering on and then it went dark with the image visible only when viewed with a flashlight. I found this thread after a quick Google search and tried pulling the #15 DIM wire. I felt a great sense of accomplishment but it went away after five minutes...

Re: New Members - please post your introductions here

Hello. I found this forum while searching for a solution to a blank screen on a LED TV my employer was going to throw out. My electronic skills top out at replacing screens on iPhones, batteries on iPads, and processors on desktops. I'm only somewhat familiar with DC circuits and multimeters are a bit foreign. I'm a jeweler with a penchant for tackling problems that I have no business even attempting. It's fun to tear things apart so if it's already broken why not try to fix it? I've got a couple other electronics projects that...
