17IPS61 Failed After 540 Hours !

[ReeceyBurger123]

Got this Linsar 22" Led SMART Tv here rebadged Vestel junk, shorted SB5100 output diode on the Psu. Simple repair however upon opening the service menu to find this only has 543 hours (33,000 minuets) on it lol wtf thats bad this thing cost £130 new as well to only last that long what a joke !

I had a low hours Vestel-Turd a while back. It had PFC issues and about 400 hours, Cant remember what name on the front, but had a 17PW26 type PSU...

What can we expect?--it IS Vestel, after all--Utter Junk!!

What amazes me is the well thought of makers are rebranding this shit as their own....

Re: 17IPS61 Failed After 540 Hours !

Its just trash other option to solve this diode issue is install a proper rectifier with heatsink even then a tonne more issues on these nasty Tv's.

Have you ever looked at Vestel website?

http://vestel.co.uk/about-vestel/vestel-group

For such a shitty maker of TV's the website makes 'em look like Mercedes-Benz, when in reality they aint as good as a bad Moscovich or Austin-Allegro....

Bet a visit to Vestel City would a real rip-roarious day out for all the family!

Their headline is--

Amazing Products, Amazing Technology, Amazing Prices

Whats amazing is they cant even make a TV set last as long as a cheapo Lightbulb!!

Re: 17IPS61 Failed After 540 Hours !

I love their bullshit quote "highest quality technology for customers and clients" my answer is no to that. Who ever wrote that probably hasnt seen how shit their Tvs are lol

Also happy new to you buddy !

Aye--True!

Only an hour or so to go, Hope you (and everyone reading this) has a nice happy New Year and a good 2016....
--I Even wish the TV set designers at Vestel happy new year....

Cheers you too

Least I've seen is 8 hours on a Samsung 22"!
Had bad diode on output, and blown input fuse... Not sure what happened there!

Dont think I can beat that lol Tom have a good new year

Re: 17IPS61 Failed After 540 Hours !

If you scope the anode of the diode you will see it is blocking reverse pules of some 90v , the SB5100 only has a peak inverse voltage of 100v , another cause of failure could bad bad design , you should not put diodes in parallel unless you add current sharing resistors to each one , no two diodes will have identical characteristics so putting two or as vestel do 3 in parallel, one always will pass more current than the other 2 .

Definitely. Could not agree more. Actually when I scoped the 17PW25-4 I was seeing pulses of 280V, for diodes rated at 100V. Terribly sloppy design, no idea how that ever passed any kind of internal testing--I get the impression Vestel don't do any!

Hi Tom , I am glad you have replied to this message , I was hoping to get intouch with you as you seem like a pro and I think you may be able to help me, I am new to forums however and I dont know how all this works at the moment so strugling to navigate its use.

If you have a question just create a new thread. After your first post you can create a thread. So you should be able to do that now.

Not good with computers, I cant find a box that says new thread.

Hi Tom , Many thanks for that I have just done one now .lets hope I can get back to it if I get a reply !

As a service workshop, I bless Vestel for making these wonderful power supplies with three schottkys SB5B0 or SB5100 that one (and only one) of them shorts. It’s a fast, easy and reliable repair, and it’s not MY fault.

Haha not too bad on the LED sets but it's the 17PW25-4s that are awful as the primary usually goes bad when the secondary diodes short.

Re: 17IPS61 Failed After 540 Hours !

If the 24v diodes on them PW25's that it the primary side has a meltdown but if the 12v ones do its fine just wont turn on lol
