Re: UN55KS8000 T con or screen?
They were asking $240 lol but could possibly get it lower. Looked like an easy fix but this time I'll pass.

Re: Samsung UN46D7000 Turns on and Off
I have un46d7000 with the constant reboot problem. Found a replacement board for a good price, these boards are pricy. Installed the new board, it's still rebooting. Is it the nand chip or led strips?Leave a comment:

Re: Lg 50ln5700 horizontal moving black line on bottom of screen
No matter where I place the tape couldn't get rid of the black horizontal line.
Until I watched a movie, the movie had black borders on top and bottom.
It looks perfect with the top n bottom black borders. Just gonna give this tv to my parents their Comcast cable box has the up down black borders on every channel....Leave a comment:

Hello bought this tv with intermittent back light a few months ago and finally got time to work on it. I replaced all the led strips have full clear picture but now slight horizontal line that seems to move on the bottom 3 inches of screen. Already cleaned and reseated lads cables to tcom. Bad panel?...Last edited by Gdog215; 12-22-2018, 03:03 PM. -
Re: Ex Serviceman Needs Help
Try unplugging the main board from the power board, than power on the tv. See if the backlights come on first than you will know if your power board is good and main board Is bad. You should get a lighted blue screen. Try that first.Leave a comment:

Re: Any Panasonic Viera lcd tv experts?
Went to check voltages on p2 but noticed when the tv is plugged after awhile clicks and the red light blinks 13 times. The service manual says 13 blinks is emergency sos comm error between ic 8007 and ic 1102, check point a board. Flashlight trick pressing menu still black screen. Used my Apple TV with screen mirroring through iPad no picture or sound. Unsure measuring voltage on p2 connector, never saw a connecter like that on a tv attached as picture. Also tried to test voltage on the big cap dc voltage was 516 volts if I did it correct...Leave a comment:

Re: Any Panasonic Viera lcd tv experts?
I really need to brush up on my meter testing skills on a live tv, as I’ve been shocked before while playing around with plugged in tv power supplies. This tv has been sitting in my basement for some years as career got in the way. But a hint when I first bought the tv was told that it needed a new transformer. Will try to check the flashlight trick and check for the menu and get back to you guys.Leave a comment:

Re: Any Panasonic Viera lcd tv experts?
Upon researching this tv I found that there is a small sq101 bulb on the power board. I read disconnecting the 2 backlight connectors from the power board than powering on the tv. Looking at this bulb seeing if it lights up or not would determine if the problem were the backlights or power board itself. Mine did not light up, so I'm thinking issue with the power board. Also noticed a big yellow component on the power board looks slightly burned. Maybe a transformer?
What do you guys think? Maybe buying a cracked power board same part...Leave a comment:

Re: Any Panasonic Viera lcd tv experts?
A lot as I’m laid off as a systems pos pc technician looking for full time work, I’ve already fixed 3 TVs this month, waiting for my friends income tax so I can unload. Got the tools meters and rework station and am fascinated with these damn TVs. Will study the service manuel. Thanks BudmLeave a comment:

Re: Any Panasonic Viera lcd tv experts?
Either or as the boards for this tv are still kind of pricey, probably will use just as a spare room tv. Because the resale will probably be low. The component level fix will seem like a challenge I might try though.Leave a comment:

Hello, I have a tc-L37s1 with a steady red standby light that won't turn on.
No video, audio or backlights. When pressing power I get a click and a red light no blinking and a black screen. First Panasonic I've tried to fix.... -
Re: What causes dead pixels?
Damn was a nice Sammy 50 inch led with no power no standby light paid $25.00
Ordered a new ps for 12 bucks, this morning disconnected mb from pb, Backlights worked saw what looked like stuck pixels on 1.5 inches top right screen. The rest of the screen looked good. You live you learnLeave a comment:
