Re: TCL Model 55S405 - No Pic, No Backlight, No Sound - HELP!!!
Hi nomoresonys.. when you say to "look at the back cover without removing" do you mean the stickers on the back of the tv that contain info like serial number?...

Re: TCL Model 55S405 - No Pic, No Backlight, No Sound - HELP!!!
Hi nomoresonys. I hear ya. I'm experienced with replacing parts on laptops and I built my own custom PC if that qualifies me for a "techie." Not completely inexperienced by those standards. It does seem like an easy fix just a matter of dialing in on what part should be replaced.
The tv itself is enticing me to keep it to fix it. The only drivers keeping me from embracing it fully are the viewing angle which gets cloudy and the low brightness level. I want a bright tv not one...

Re: TCL Model 55S405 - No Pic, No Backlight, No Sound - HELP!!!
Hey bud.. and to the rest of the guys. I found a TCL tv (TCL 55R625) with broken screen with same size screen (55") but different model. Is it possible to take the display from my TCL 55S405 and replace the broken one in the TCL 55R625? Will it fit??

Hello to all you guys and bud. So I went out to buy batteries for my multimeter. The store that carries it is closed today sunday but will open tomorrow. Tomorrow I will buy them when they open and will begin testing! Excuse the delay and appreciate all your patience.

When the super handed me the multimeter he said I should swap out the batteries if I encounter poor performance with emphasis to switch it off when not in use. Although the digital read doesnt seem to be fading as an indicator of poor battery, I'm not taking any chances. Most of my house's outlets were checked. I even tested it at my neighbors. Same result. Henceforth I am stamping it as defective.
Regarding GFCI, my apartment building was built all the back in 1906 known as a pre-war...

Re: TCL Model 55S405 - No Pic, No Backlight, No Sound - HELP!!!
I'm a bit confused by your analysis. If the readings on that multimeter are sporadically inaccurate then it follows that theres something electronically wrong with the multimeter per se, not the wiring in my house. If not it would be common sense to expect all my devices to be unable to function correctly, namely my gaming PC which is sensitive to electric changes. As I've mentioned before I will buy new batteries for the other multimeter to test.
I am grateful for your concern for my safety....Last edited by koolx; 07-04-2020, 09:17 PM.

Hi bud and diah. I retested it on the 300 ac scale. I get very abnormal readings that jump eccentrically from 1.0 - 155v. I think its possible that this multimeter is busted. I'll go ahead and use the sperry multimeter. But I need to buy batteries for it. I'll let you know by tonite or tomorrow when I test it. Thanks for your patience with me!

Re: TCL Model 55S425 - No Pic, No Backlight, No Sound - HELP!!!
HI bud. I'm now using another multimeter made by MCM Electronics, model# 72-7940. The super tested it out on my house outlet which showed around 78 volts. But he says it should read 110 - 130 volts. We tested it on most of the outlets in my house which showed the same reading. He assures me the tool is working correctly. I've posted a pic of this for you. Let me know if the dial is set correctly.
As to the boards here are updated pics. Hope they are to your liking!...Last edited by koolx; 07-04-2020, 02:19 PM.

Sure I'll have the super help me with that. But fyi I'm not sure you read the last part of my last reply. I edited it after posting it. Just wanted you to know that I made a typo in the title of my thread. The correct model of my unit is 55S405, NOT 55S425. I sent a note of this to the mod and hopefully he should correct it.
I'll let you know when I'm ready for your instruction. Thanks bud!

Hey bud.. I read the manual that youve attached. Although I'm no techie I get the gist of it.
As for a GFCI outlet, I can possibly get one from my super. I'll ask though I doubt he has one.
Below are the pics as you've requested...
[B][U]***CORRECTION*** My tv is TCL model 55S405.[/U][/B] Sorry for the typo in my original post.. I'll change it!

Re: TCL Model 55S425 - No Pic, No Backlight, No Sound - HELP!!!
Hy bud.. ok so my super gave me his sperry mulitmeter. He also gave me a "pen" to check for other measurements. I assume the pen will be used to check the led strips. Let me know if both these devices will suffice and how to start fixing my tv.. thanks bud....Last edited by koolx; 07-03-2020, 03:12 PM.

Re: TCL Model 55S425 - No Pic, No Backlight, No Sound - HELP!!!
Hi bud.. I did reset the tv through my roku remote while the it was dark. After that I'm able to see "TCL Roku TV" flash once for a split sec but thats it. I can repeat this many times but the tv still wont turn on. Given this do you still think its an led strip issue or something else?
Btw I'm trying to get that multimeter.
Also if its an led strip issue and I buy led strips, do I have to solder them onto the tv?...Last edited by koolx; 07-01-2020, 04:02 PM.
