What can I do to fix this ?

My tv keeps flashing on and off with the Hisense Roku logo, I done hit the reset and unplugged it ? Any suggestions

Tv is Hisense Roku
Model: 70A51HUR

I tried the power reset thing, and to be fair they did come on for a very short while, then died again.

yes tried multiple devices , yes tried multiple leads , yes tried different ports and i also tried factory reset.

I did see a vid of essentially just throwing hot air at it with a heat gun to reflow, but all over though. i have a hot air station so i can be more precise if i knew where to point it.

Any offerings? Yes the TV is old , Yes i am getting another, this is just a quick fix whilst i save up for a 56" one.

It does say connecting then its the usual no signal as all the other vids show.

Hello

I need someone's help urgent with my TCL L43s6500

I have a TCL TV, someone gave it to me for use but it's not working. The tv turns on like normal BUT, Theres a dark blue screen with no TCL logo nothing, no audio, just a dark blue screen. I tried going to recovery mode but just won't work. I tried using AI's help, but it says it's a backlight issue, or it's the motherboard or its the firmware. I would like a suggestion on what's wrong with it. Is it Hardware or Software related?

My sanyo tv has recently stopped turning on for no apparent reason. Everytime I turn it on it instantly turns off again. Does anyone know what might be wrong? The model number is FW40D36F B and it was manufactured in March of 2017.

My LG 65UJ634V (65") suddenly became very dark, without me changing any settings. Here's what I've already checked/tried:

• Backlight set to maximum (100) in picture settings → no change
• Ambient light sensor and energy saving disabled → no change
• Another pictures settings → no change
• On/Off → no change
• Left it unplugged for 10 hours before plugging back in → no change

The screen still turns on and is watchable, just far too dark, and this is uniform across the entire screen (no zone darker than another, no localized color tint like blue/purple)

For context: I previously (in 2021) had a different issue on this same TV (one zone had a blue/purple zone), which I fixed myself by replacing one LED backlight strip by using :

This time the symptom is different (uniform, not localized), so I'm wondering if the culprit is instead:

• the power supply board / LED driver no longer supplying enough current to all the strips
• or something else I haven't identified yet

Has anyone run into this exact symptom (total uniform dimming, not localized) on this model or a similar one?

Thanks in advance for any help!

Am I screwed

Insignia NS-50DF710NA19

Phillips 58PUS8545/12 2019/2020 model. Screen just started flickering at the top corner. But as of now It’s stable. No more flickering. But the white edge still stays like that. But it’s not flickering

Hello! I have a Samsung CU7000 Smart TV (55 inch) and it has a thin black vertical line about 1/3 the way from the left on the screen. It goes the full length from top to bottom and it doesn't change position.

Unplugged HDMI, power cycled, did picture test to verify source and its still there.

Am I cooked? :@
