My old Samsung 'claw' TV is showing signs of fatigue.  Damn thing's not all that old either at 5-6 years old   I remember at the time the Samsung was the TV to get.  Does anyone keep up to date with whats good in the TV world?  Not after 4k or curved; just a normal TV.

Trust you to 'tune in' to this thread.

I had problems with Samsung PSU going bad , so would not buy again. Sony has been fine for past 10 yr, only looking to replace to go 65/70" as want something to also do VR / simulator dual use with pc

I also had a Samsung PSU go bad after 18 months, but fortunately I managed to buy the correct board off Ebay for £20, fitted it in an hour or so and it's been fine ever since. My general observation would be most non "flagship" TV's in any manufacturers range are built down to a price and are pretty much disposable within two or three years. The Panasonic TV I also have is eleven years old cost 3 times more than the Samsung that went bad, but the picture on it is no where near as good as the more modern cheaper TV.

FLD, what sort of screen size were you thinking of getting?

Siztenboots, TV's with variable refresh rates up to 120 frames a second are about to become The Next Big Thing for gaming/simulator use, as both the next X box and Playstation can support this feature. A PC graphics card would need either G-sync (Nvidia) or Freesync (Radeon) to make use of this. Look out for TV's with HDMI 2.1 inputs to ensure compatibility.

Fairly flexible TBH.  I think the current one is 50ish and was on the smaller side of the range.  I don't want to go massive though, just a regular flat TV. 

 

Is there any way I can diagnose what's wrong with my TV?  I'm quite happy to have a go at fixing it.  I have a couple of horizontal lines across the top of the screen.  Looks like dead pixel lines but when you get up close there's some colour in them so not dead just dodgy.

Isn't 50cm quite a small TV by modern standards, ours is almost that and it's quite old

[FLD]

I'm taking inches but thinking about it there's no way its 50".  Ive had a look and its 40".  Model is UE40F6500SB type UE40F6500

[siztenboots]

Richer sounds 6 year, or John Lewis 5 year give a much better guarentee 

[FLD]

There's a thought....

It came from JL.  I'd best check the actual purchase date.

Regarding samsung, they use QLED technology, where the competition uses OLED.
That results in samsung tv's (even the more expensive ones) to have a degrade in view, when viewed from an angle.
This starts allready at 30%. Just google for it.

Go for OLED, not QLED.

OLED is fundamentally a better idea than LCD because the pixel generates the light rather than blocking it. This means they are capable of displaying true black and any accurate picture is built from this foundation. The only downside is OLED's are not currently capable of quite the same peak brightness as LCD based technology, so not the best choice in very bright rooms, but for most situations this isn't an issue. The only company actually making OLED panels is LG but various manufacturers including Sony and Panasonic use them and differentiate themselves by how well they get the panel to work using their own video processor technology.

FLD, I'm no electronics engineer (not enough hammer usage for me 😁), but given the fault symptoms for £25 this t-con board has got to be worth a punt

If your TV is anything like mine be prepared to grit your teeth as you prize the back off - it constantly felt like I was about to break something, bit like pulling trim off my old Fiat 🙂

And if that doesn't work and the budgets there buy a 48" Sony OLED from your friendly local independent retailer 😉 (not me, haven't done that for over 10 years)👍.

Awesome tech knowledge there!

Can I just ask what a T-con board does?

[TheHood]

Timing connection board. It takes the signal from the main video board and uses it to drive the display panel - a bridge if you will. However, further research suggests your problem could be power supply related, although intuitively that seems less likely.

As long as you can find the right used boards for not much money it could be worth just playing "board battleships" and replace them all in turn until the problem is fixed or it turns out to be the panel, in which case it's a write off. There's only going to be 3 main boards - power supply, main video board and t-con. You'd be suprised (or perhaps not...) by how many of the less skilful sevice engineers I've met that make a living out of doing just that 😮

thanks for this, a fantastic explanation!  I bought the tcon and just need to be irritated enough by the lines and brave enough to take it apart.

Looks fantastic.  £2850 though!  Might give it a look to see if it's suitably awesome to justify that price.
