LG Television: LG 55LM5850 Dark Screen

Thu, 25 Jun 2020 09:15:30 -0700

I have a 5 year old LG 55LM5850 3D TV that up until 2 days ago worked fine. It comes on for a bout a min. or so and then the screen starts to darken to the point where there is no bright lit areas. The screen is dark and you can hold up a flash light to it and see a faint picture. sound and everything else works fine. I realize its at the 5 year mark and I am going to replace it. however, I would like to look at fixing it my self and wondered if any one had any suggestions?

TCL Television: Is this a bad t con? Don't know much about t.v.

Wed, 01 Apr 2020 19:56:02 -0700

I have a 55 inch TCL roku tv. a couple months ago it started having vertical lines on the left side of the screen, so I switched it with the tv in the basement which we barely used. It occasionally would have so many lines that you couldn't even see the picture but after being on for a few minutes, it would call down and only hab e a few lines, and still be able to watch. Now the screen totally went black, but still has that I guess black glow, like when it is on an input with nothing connected. The sound is fine. could this be a t con problem? also, when the screen was working (still with lines) when I would power on, and it said “TCL"…. there were no lines, they would come right after this screen came on. Please help, I am broker than broke and can't afford a new t.v!

Samsung Television: Samsung UN58H5202AF Television won't turn on and no standby light.

Sat, 01 Feb 2020 07:39:35 -0700

Hello,

I turned on my television, 58” samsung UN58H5202AF, this morning and watched it for about half an hour. I then left the room for about 20 minutes leaving the tv on. When I came back the television was off and wouldn’t turn on and there is no standby light in the bottom right corner like usual. There was no power outage in the house and the cable box and streaming box that are plugged into the same power bar are both working fine.

I searched on here for solutions and found the solution to unplug the television and then hold the power button on the tv for 30 seconds and then plug it back in. This didn’t fix my problem.

I’ve also seen that there is a class action lawsuit against samsung for faulty electrical components in some of there televisions. I’m not sure if I fall into this category or not.

I also tested the ceramic fuse while it is still on the power board with a multi-meter and it seems to be fine, although I did read that testing it while it is on the board may give a false reading that the fuse is still good. But I couldn’t get the fuse out easily and didn’t want to break anything.

I’ve also read that there are poor relays on some models of samsung televisions and if you tap on them it will solve the problem. I however am not 100% positive which is the relay and what I’m supposed to tap on.

Here are pictures of the model, a sticker inside the tv and the power board itself if they provide any help.

I hope this gives a good enough description of the problem for someone to help me solve this. The TV is only a few years old and I don’t really want to replace it if I don’t have to. Thanks in advance for any help anyone can offer.

LG 60LM6450 60inch Full HD 3D LED Television: My 55LA6205 LG TV turns on and has audio but NO video.

Sun, 01 Sep 2019 16:00:08 -0700

No video but audio is ok. I used the flashlight test and I was able to see some dim letters and video. Then I opened the TV up and checked the power supply board-- all the voltages work except the 24 volts one. What do I do in this case??? No blacklight btw.

I checked using the multimeter the pins on the power supply linked to the main board. It was easy because there was a chart that mentioned the amount of Voltage for each (ground, 12 V, 3-5V, 24 V, On Off etc)

The other one linked to the backlights has no chart only Led+ and Led- and I honestly have no idea what to expect in terms of voltage for that one.

But for sure, the 24 volts one on the power supply board linked to the main board showed zero. Actually -1! (An error?)

UPDATE: I measured the voltage at the pins leading to the backlights and these were the results:

LED + : -1! (Some kind of error? Same result showed for 24 Volts I mentioned above)

LED -: 0.38

LED +: -1 !

LED -: 0.28

I guess the power supply is not reaching the backlights. How to fix this? Do I need to replace the whole board or keep the board and just change some capacitors or components in the board? If so, please advise on what to do.

LG Television: Why won't my TV turn back on? LG50LN5200

Sat, 17 Aug 2019 13:17:17 -0700

Last night my TV abruptly turned off and wouldn't turn back on. There is a static red light at the bottom of the tv showing power when turned off but plugged in. After the tv turned off, this light did not come on although it was still plugged in. When I unplugged and replugged the tv in, I noticed that the light was now on but very dim. The tv still would not turn on. I left it unplugged overnight. This morning the tv turned on and worked for a couple of hours until repeating the issue. I was informed that this is very likely a power board issue. I'm trying to get a confirmation and whether just a component needs to be replaced or the entire thing. Attached are pictures of the power board.

LG Television: To Repair or not to Repair

Thu, 14 Feb 2019 07:16:48 -0700

Heard a pop and my year and half old 60" LG plasma TV (60PB6650) screen went black. The power indicator light started flashing and the TV was making a clicking/ticking noise.

Hoping to get a ball park cost estimate to repair based on problem description to determine if I should pay to have it repaired or put the money towards a new TV.

The TV stopped displaying any pictures for any devices connected to the 4 HDMI inputs on the rear of the set. I've connected DirecTV, Cable, and my receiver to the all of the HDMI inputs with no picture displaying. I've reinitialized the set using both Menu2470/initalize/enter and Menu123enter/initialize reset the inputs to the HDMI 1 set it for cable and still nothing on the screen or audio. The components still function with the expected lower picture quality

Television: Backlight turns on with TV then off.

Sat, 03 Nov 2018 06:24:42 -0700

Hi, I got a Magnavox 40in LCD TV (40MF401B/F7) with a display problem.

When I press the power button, the tv turns on and lights up and the words “DIGITAL TELEVISION” are displayed, then the screen goes dark.

Picture is visible when a light is shined into the screen and sound plays fine. Problem persists on HDMI and Component inputs with different devices.

Vertical black lines also sometimes appear within the picture and did so before the screen stopped working. Checked tv settings and all appears normal but haven’t yet found how to do a factory reset.

Any suggestions for some diagnostic or repair steps would be greatly appreciated.

Thank you!
