Thanks Alan. I dusted off my old 32 Toshiba that it stuck in standby. The caps of the power board have no bulging but I guess I will have to test each cap individually and hope the Eeprom is ok .

Thanks for this i have a 42 inch version of this

I use my mobile phone camera to see if the remote is working ...

You can buy a new TV for less than £300, so why bother to repair them?

please what will your addvice be?I have the same TV, i took it for repairs and each time it doesnt last for more that 5days the backlight goes back off again. Should I still take it to another repairer or just dispose it ?

I'm pretty sure with Samsung smart tv's, the splash logo which is part of the bootloader, doesn't come from the NAND it comes from the EEPROM?

Slightly better, allen

the little bush tv might make an ok lone tv for someone who needs a tv quick

Allen that Samsung unplug the screen, I’ve had a Samsung Qled which turned on similar to that one and then reset it was a short on the screen, blocked lines all ok now worth a try 😊 Oh p.s there is a buzz on the mic you’re using 😊

Mic 👍

My old Japanese made sharp lc32d44e TV I decided to test it with thoughts of using it, and it worked for 10 minutes then died no standby or error codes not sure if it is the PSU or main board .Caps look fine no bloat or signs of leaking not sure if main board or PSU failure there are cheap boards on eBay but i think i will give up on it .

Lots of mains hum on your regular mic, test mic was great. But as you said, a PITA to hold and I wouldn't worry about it. It's the content that counts and that's what we're here for.

Your other mic is better than the lapel mic your using.

Back when I bought my UE7000. Only difference between that and the 8000 was a nice metal bezel.

Better quality, yep, better than the lapel

Also a lot of buzzing noise on your other mic,I am wearing headphones so maybe picking it up more

It sounds much better

shure u dont mean ,, self imploding tvs lol.

I got a sony 42ex443 it had a really shaky picture but its too late to mess with now as its gone out side and someone took it

Cheers Al, another one saved from landfill.

That was Vince in desguise :-) I did tag your link on his YT channel.

Great Allen you’re right they’re built to last unlike the newer ones 😊

Grest video thanks Alan. We're the symptoms no standby?

Lucky Goldstar cheap load of rubbish

Actually even reballing won't help for long, it's a well known problem between CPU silicon die and substrate with these flip-chip CPU:s. Heat during reballing process cures it temporarily.

Yes it would be nice to know how much does it cost to have a reball

still have my LG LH 3000 32 inch tv its a good tv.

hard to reflow non leaded solder. I've had success using flux and heating to 240c for around 8 min after a pre heat using a fairly large heat gun. I then fit a heat pad after cooling between the heat sink and chip to physically push the chip down onto the board. no good putting in an oven at 200c for 10 min as some UA-cam channels suggest as it doesn't last.

Most people run the backlight at 100% (factory default) and after 3-5 years the LED's will break. Some TV's get a bluish picture and some white spots. Decrease the backlight and the LED's will last much longer.

Nice one Allen would of been a shame to chuck it nice fix 😊

And what is the cost of Re balling the main board ??

Buna ziua ,apreciez ceea ce faceti si va respect foarte mult,dar va dau o sugestie incercati sa filmati cu camera de deasupra ca sa se poata vedea piesele si cablajul ,nu trebuie sa va vedem pe dumneavoastra ,trebuie sa vedem ce lucrati si de aproape . Ex 12 voltvids cautati pe youtube.Va salut cu tot respectul.

Another saved from landfill. Selecting too high a working voltage can result in more ripple due to a higher ESR. My rule of thumb was around 25% greater than the expected voltage, but I used 50% greater many times, many moons ago. Measuring leakage on the original caps may have shown something.

the person who bought the Samsung UW17J11VD of me only gave me £20 for it and now selling it for £365 on ebay what a piss take. I say there only worth £85 most.

Both garbage TV’s

made when vestel built solid tvs

Super super video thank you Allen. Looking forward to watching the LED conversion.

Hi Allen, love your channel, have been subscribed for some time, I just love how you make every repair look so easy. I would like to ask you, sir, if you don't mind a couple of questions regarding a Samsung 40'' TV that I have been given by a neighbour, who explained in his words, It just went dead, black screen no picture, but still had sound. The TV details are as follows: Model: LE40R74BD. [R] S Type No. BD40EO MODEL CODE: LE40R74BDX/XEU Serial No. AES53SCL900860V Version: SPO1 I've plugged the TV in and connected the HDMI cable from my SKY Box. When I hold a torch up to the screen, I can see the picture faintly in the background. The sound incedently is fine. My questions are: 1. I think it just requires new backlights, or perhaps the constant current driver board could be faulty. 2. If indeed I do need to order new backlights, what information do I need to source the correct backlights. Do I search by TV Model number, or is there some other information required. I'm fairly confident at doing this repair myself. I've been studying electronics for many years as a hobbyist and have all the required tools. Apologies Allen if this is somewhat off subject, but I would appreciate any help you could give to point me in the right direction.

I do follow my mate vince will drop the comment and link to this video to let him know .

Nice fix Allen, I’d test it after it’s been off for a while as even soldering them can make them work and then not work when it’s cold😊

Have a board from a NU7470 same BN number as one shown on your video. Taken from an old tv of mine that had screen smashed, working at time of removal

I don't think it was the 50 volt capacitor that make it fail. Probably a bad solder joint or the capacitor was bad.

Hi Allen, are you sure about the £1000 thing? Reason I ask is I bought an end-of-sale Marks and Spencer branded Cello 39" set in August 2012, and paid £199 for it. Still had it until a couple of years back when it was dropped and the panel smashed. It was a decent TV with a good picture but the CCFLs were noisy, there was a slight buzz when the set was switched on from new that was noticeable at night with the sound turned down (it was a bedroom set). This was a very good deal at the time but it wasn't "fifth the price of everything else" cheap! As an aside, the "JVC" branded 40" (not Vestel, the Chinese variant) that replaced it, has already developed noise on the audio output, I must pull the back off at some point and check the caps going into the audio chip before it lunches something 😂

The latest sets won't last as long as these ones have. Sadly Hitachi is another one of the once famous japanese brands that no longer makes their own products. Strange how they are so sensitve about having exactly the same values and votage rating of capacitors.

Watched it this morning thought I'd gone deaf Allen

Jvc has smart function now ?

Mine does the same once in a blue moon a power cycle fixes it.

This is better, i thought my PC had no sound !

it is so great that you Try to Repair these Flat TVs, so much TVs can be Rescued from the Trash.
