Faulty plasma TV - attempt a fix or just bite the bullet and upgrade?

Found 5th Jun
Hi all,

I have a rather dated Samsung PS43E450 43" plasma TV that was purchased in June 2012. It has served me very well over the years.

However today I've noticed that I can no longer switch it on.

The red standby LED lights up, but it blinks twice every three seconds. The TV doesn't respond to me pressing the nipple On/Off button under the panel, nor does it respond to any remote control commands.

I have unplugged it from the wall and left it for a few minutes and plugged it back in to find that the red LED standby light continues to blink twice in quick succession, and keeps repeating this sequence every 2 to 3 seconds.

I've called Samsung who say it's a power supply fault, and that I'd need to get it repaired. They gave me a phone number to call - 02082086990, which goes unanswered. I've tried calling it a few times.

Now I have to be quite honest, I am quite tech savvy and am not afraid to take things apart. However I haven't got my hands dirty in a while, since I no longer maintain desktop PCs thanks to the advent of high performance smartphones and tablets.

I have been browsing eBay and have found a power supply for around £16.

Seeing that the TV isn't currently working, and that I have never taken a TV apart before, is it worth taking the risk?

I mean, the telly is a good few years old now and while it does (or did) offer great picture quality, I appreciate that its resolution is rather low now and if it isn't worth doing the fix, or paying someone to do it, then I guess I will just have to fork out for a half decent 4K TV.

Many thanks in advance,

Plasma TV's differ slightly to LCD/LED TV's in the power supply department, usually there is a 'panel voltage' written on the back of the plasma panel itself - this is a calibration value which must be set on the new PSU.

You would need to set up the new PSU to the panel voltage, it's fairly straight forward normally and you adjust an internal pot whilst reading a test point with a multimeter = set the voltage accordingly and you're good to go.

I think you should give it a go and DIY. check that link I sent ^
My Panasonic Plasma is now 11 years old and still going strong.

I'd have a go at a cheap repair myself - if that sorts it you've probably got a few years left in it. If you can't repair try selling it for spares/repair on Gumtree.
I suppose the decision is up to you , but it does seem like you want a new TV anyway
Saying that though for the sake of £16 I'd have a blast at fixing it then sell the TV on or keep as a spare.
But I believe they store some residual energy so you'd need to be careful and keep the static to a minimum.
Get the part...you know you want too. Worst case you lose £16...and the possibility of death by electrocution of course
I had the same problem a couple of years back, although power was going through to the tv it was too weak to actually fire it up. Had it fixed under an extended warranty and now it’s 10 years old and still going strong.
I've just bought a 2nd UE43 to replace an old panny. Richer sounds clearance. £310. Last years kit but unopened box with 6 year warranty.

I had a search running on ebay and noted you can get loads of parts for samsung tvs. but all at quite inflated prices
Thanks so much to everyone who has replied so far. I really appreciate the help and feedback.

I'm actually shocked in a way; I've had far more help on the HotUKDeals and MoneySavingExpert forums than I have over on AVForums and Digital Spy. I presumed that there were going to be more replies on the latter forums since they're dedicated to this type of sector. I haven't had any replies on either forum, but on MSE and HUKD I've had plenty of replies.

I've taken the decision to take the back off the TV and have a glance at the PSU. If the PSU looks like a total goner, I'll take the risk and buy the one I've seen on eBay for £16. Also, I will assess how easy it looks to replace. I'm not confident with soldering irons, so if it only involves screws, as well as precautions regarding static and residual voltages, then I'd give it a shot. If it looks too dangerous and/or if I don't think I'll be confident in doing it, I'll just recycle the whole TV at my local recycling point and buy a new 4K 49" or equivalent.

Thanks again to everyone.
It will very likely be one of the capacitors. Have a look to see if any look like they have got hot or have expanded.
I'd be surprised if a PSU replacement needed soldering, I'd expect it to be cable connecotors
