OK I see what you mean now .. looked at the board pins like you said Diah. Thanks for the tips and suggestions all. I will try this when I get a chance. I will have to research it a bit before I attempt it .. skills are not very good lol. -
Hi Diah thanks for all your input. Do you mean the Red wire is BL_ON? and jumper it to where? with a 1KR? is that a 1 K Ohm Resistor? .. sorry dumb here lol ... just an amateur. Appreciate your expertise.Leave a comment:

I have same problen with one like you ... don't think it is your power supply or your leds either. I picked up a free TCL 43S446 get standby light and works without backlights turning on ... but no power to leds. Ordered another power supply and was garbage didn't even get any standby light .. so put original back in. Than went and ordered a LED replacement strip .. same thing as original .. and still no backlight on power tv on. At this point It has be something like bad circuit on the panel. I have not went back to it yet. I think all these models are suffering from the same flaw.

Some good quality toothpaste on a soft cotton cloth and buff in circles with light pressure so as not to crack the screen. Toothpaste has microscopic granules in it almost like a very fine sandpaper. Works great for light scratches. Won't harm any screen films. Just wipe off with damp wet rag or paper towels. Won't work for deep scratches though.Leave a comment:

Oh ok thanks for that advice. I did not know about that zener diode protection. Thanks Diah! wonderful advice. I will have to check that out. I will wait for the new board anyways to see what happens, before ripping it all apart again lol.Leave a comment:

Hi Diah yes you are right thanks for your advice my friend. It's just going to cost more for diodes and stuff like 15.00 or more. I figured I might as well just order the whole power supply for only 22.00 and won't have to screw around removing capacitors and diodes etc. But I will try to repair the old one. Apparently these diodes on power board crap out frequently. Diodes Schottky SB5200, MBR3200 diode. I will see if I can find some off some old boards.Leave a comment:

Ya these TCL's are very temperamental lol. Done several of them all sizes. Right now working on a TCL 43 Inch 43S446-CA 4K Google Smart TV works great but no backlight and panel is ok. Model only has one led strip.Tested backlight and all leds individually and they are ok. Only has one LED strip 21 x (6V Leds) running at 5.238 Volts each. Measures total 110 Volts powering leds on tester. I powered the backlights seprately with my tester and everythings working when viewing tv on and watching .. but if I power the leds from the power supply board normally the screen just does not light up. So I...Leave a comment:

No I never tried it yet test.testary ... but thats my plan since the strips are obselete/discontinued and mostly all gone. The WG55UR4100 I have I used a bunch of the strips to fix another identical one. So now going to just get the 3P55TA004-A0 and use them to get this one back up and running when I get to it.
They are good tv's still and have nice picture even though they are older 2017 or so models. Still actually better than most the garbage they are pushing now.
WG55UR4100 uses 10 strips (5 x 3 volt leds on each strip) 3P55TA004-A2
WG55UX4100 uses 10 strips (5 x 3...Leave a comment:

That's correct 3P55TA004-A2 and 3P55TA004-A0 both will work. I have had same tv sitting here for over a year and have not got around to getting leds.
Westinghouse WG55UR4100 TV is same as Element E4STA5517Leave a comment:

Thanks for your input Diah, Davi.p.. if I understand correctly your advice is that you would not bother with this Samsung. I will take your advice ☺Leave a comment:

I don't actually have the tv ... I got an offer to trade a working tv for the Samsung with the vertical line. Just wanted to get some expert input from here. Yes I was thinking along the lines of what EazyBone says ... worst case scenario bad panel .. than I am out a good tv that I will have traded for the bad tv. And Diah is right too would be nice to actually see inside before doing a trade, but doubt the trader would go through that. So maybe is better to not take the risk and just forget the negotiation. Than again could be easy fix lol .. Ughhh hate these kind of choices. Thanks for the input...Leave a comment:

Samsung QN65Q80AAFXZC QLED TV has a white vertical Bar
Hi all Happy Holidays! Was just wondering if you think this white vertical bar would be fixable. Maybe bad TCon or ribbon cable? Contemplating trading a 50 inch Hisense 4K Roku for the Samsung but might get burned lol. The Samsung is model QN65Q80AAFXZC QLED TV has a white vertical Bar. Any thought appreciated. Thanks. -
Re: 55r6095g5 Hisense question for all
You need some black double sided tape. Don't use clear ... I did on my first fix on one of these and the light comes through around the edges of the screen. Use black only.
Here's a link on Aliexpress.com ... Amazon probly has it to but more expensive.

I used 5mm but is very hard to work with ... so thin. the 10mm would be better to work with.

Re: Hisense 50A6G
Hi Elmano ... With tv plugged in ... if there is a small rest button hole on the back. Did you try pushing it and holding it in with a paperclip or something for about 10 seconds and release. Maybe that will reset the glitch.Leave a comment:

Re: what to use to stick panel with no bezel
Like Zomi said ... some high quality good double sided tape. Cut small squares and place about 4 inches apart all the way around the panel. Easier to lift panel back out again if need to service. Avoid glue at all costs ... no matter how careful you try to be you will have glue all over the panel and risk damaging or smears all over the glass. Glue hard to remove. Good luck hope you get it fixed.Leave a comment:

Re: TV Philips 43PUS8505/12 - horizontal line and picture jumping
yes I have 3 RCA's with same problem, nice tv's 4K but lost interest and sure as hell not going to spend hundreds of dollars on replacement parts if not going to solve the problem. Maybe this post will renew my interest to have another look. Have heard a lot about removing useless diodes on several brands like samsung, lg, rca etc and problem solved. Hope it works for you ... will be keeping an eye on this post.Leave a comment:

Re: Sharp LC-55N7000U 1 long 5 short blinking, no display
99 percent it's backlights. Do the flashlight test in the dark to see if you can see the Sharp Logo and the images on screen when booting up ... and have sound. That way you know it's bad leds and not something else like mainboard.
Here's the LED replacement info.

This is common with all Sharp / Hisense models. If backlights are left at 100 percent from factory sale. Only last 1 or 2 years. Replace and turn them down to 60 percent and last way...Last edited by tech9pc; 06-20-2023, 10:15 AM.Leave a comment:

Re: Sharp LC-58Q7330U No Backlight
It's your backlight's. I have done several of these models. A couple been using myself for a few years now no issues. Just make sure you turn the backlights down after install to 60 or less and they will last for years. Here is link to 5 strip set. I have never had problems with purchasing here.

If the USB update from stick don't kick in / or doing a hard reset .. you will probably need to replace the main board.Leave a comment:

Re: Hisense 65H8G Boot Loop
Your tv got bricked by a recent android update most likely. I would wait for Hisense to send you a new firmware update to put on a usb stick formatted in Fat32. Than update the tv on power on with the USB update.Leave a comment:
