Redlight of Death Repair

[Rimmel]

Thanks, this sorted my friends DUO out - perfect.

Maplins didn't have any 220uf 16v in so used 220uf 35v.

Just to say thank you for this information. My 4 year + old Duo had been glichting for the last few weeks and the recordings had freezes especially on HD recordings. I could not figure out why.
It finally decided to restart over and over again yesterday and then the dreaded RED LIGHT ! Found this thread last night and got a 22 mfd 35v Cap and just managed to cut of the old one and soldered new one on. Bit of difficulty as the old ones was very close to the board but just had about 1 mm to work with! Didn't fancy dismantling the whole thing! Done in 15 mins including opening and closing up the box !! Great work !!

I have changed the capacitors C807 plus the two adjacent but still not working. I have measured the voltages as shown above and U801 has a very low voltage out so it seems the PZ1021ai needs to be replaced.

Does anyone know where I can obtain a replacent PZ1021ai chip in the UK? I have checked the site in holland but they want 11.95 plus 19.50 euros postage for what is a chip costing pennies. Similarly they want an arm and a leg for postage from the USA.

Try some where like fannells or CPC

Just did a search and someone posted that AOZ1021ai might be the answer. Εbay has these for £5.39 with free PP from HK - cheap, but might be a 2-3 week wait for delivery.

Warning, I've no idea if the AOZ1021ai will do the job.

 

[Jimdefruit]

Thanks stanman but neither farnells nor CPC do them.

Thanks Burnham but I have searched both ebay.co.uk and ebay.com including all of the chip suppliers listed and cant find the item you have listed. Can you give me a link to the item you spotted please?

 

[Burnham]

I have to apologise for the wrong information above.

I put AOZ1021ai in the Εbay search box and did not notice that it could not find anything. What I saw was the suggested "similar" - which was a AOZ1014 AOZ1014AI SOP8 IC.

I don't know enough about these alternatives to say whether they would be suitable.

have a look at RS ( radio spares ) they sell mostly everything

 

[Jimdefruit]

I have a quote from China. $0.5 for the chip. $20 for shipping. I would probably have trouble finding the chip inside the crate.

cwebb66, I had already checked RS but they dont do it.

 

[Jimdefruit]

Ok I have bitten the bullet and bought one from a seller in Spain for £12 ish. I think I will go into business selling IC chips because there seems to be a lot of money to be made.

anyone know who repairs this problem
my m8s box has stopped working

 

[Larry-G]

Any half decent TV repair man, electronics engineer should be able to do it for you for around a tenner.

Hi all,

My Vu+ Duo unfortunately exhibited the "red light of death" symptoms. After reading a few forum posts I decided to give the 807 capacitor replacement a go as I had nothing to lose.
I removed the original capacitor, leaving just a couple of short "tails" behind, and soldered on a new capacitor that I picked up from Maplins.
They didn't have a 25V as requested so went for a 330 uF 50V and this amazingly did the trick!
Thanks to all who have posted on this subject, I thought I might have to be shelling out for a new box in the New Year!

My V+ also showed the same symptoms and got the 220uf 25v from Maplins and the box started working.After 5 days it froze and when I tried to switch it on it gets stuck on STARTING.A friend of mine then tried to flash and load a new image but it still gets stuck on starting.Tearing whats left of my hair.Seems i will have to buy a new box from WOS and stick mine on ebay for spares.
