Help JVC AV-28T5SK Problems

[Brainboy]

Dear all, help!

After hanging about indecisive for far too long I finally bought a JVC AV-28T5SK from Amazon it arrived on Thurs 4th Jan 07. I reckoned it would at least be good enough to tide me over until they get LCDs sorted for sport viewing (watching football and occasional DVDs is really all I do) - alas no - so two questions please -

There are big, big areas of 'dirty screen' visible on both the Tvs internally generated blue backgrounds (unused AV inputs generate plain blue backgrounds on this set) and the usual panning shots in football - so it's not a signal issue I reckon. I have been switching off as often as possible in the hope any auto degauss might help but see only a very slight improvement, if any.

What do you think - is there anything I could do other than send it back? Is there anything more I could try?

Apart from the dirty screen the picture is ok but any text is absolutely atrocious - I have SKY digital box on RGB output, as is Pany DMR EX75 DVDR - and both feed into TV through a £30 Thor SCART to EV1 RGB input on JVC. I cannot fathom how the text could be so bad when the pic is ok - honest it's unreadable and gives you eye strain even with a quick check of SKY EPG - it's not the SKY signal as Freeview EPG, through the EX75, is bad as well (not as bad maybe but still very bad). When I look closely at the picture it also shakes up and down ever so slightly especially noticable on adverts - I wouldn't call it a flicker as it's a distinct up and down shake but I have never been able to see 50Hz flicker (execpt out of the very corner of my eye when trying) so I am not sure exactly what it looks like.

Is this - text problem - a 50HZ issue?
Is this - up and down shake thing - a 50HZ issue?

I never saw any of this on my old SONY Trintron 4:3 50Hz or any flicker - I deliberately went for only a 28" for fear I might see flicker or text issues but surely with a 28" it's not possible that suddenly I can see 50Hz text issues and flicker is it?

Help please - with junior brainboy just turned one money is very tight and if you think these issues are unsolvable I seriously need to get a refund and try again.

Any help much appreciated.

Anyone in Aberdeen area got a decent second hand CRT for sale - assuming AMAZON do the decent thing if there is no fix for this TV?

Dera all,

No replies so I reckon no one knows or cares but heads up I am retrunong it to AMAZON but they are claiming that as the return is 'not due to their error' I have to pay for postage on both orginal delivery and return - I will argue this but heads up to any prospetive pruchasers!

Anyone want to know how it turns out or has any advice reply and I will update thread as this unfolds.

If a thread drops of the first page it is often overlooked - its not that noone cares. Most people, like myself, only drop by now and again when we have a spare minute or two.

I'm not sure what you are seeing, but there is currently a known issue with certain Sky ads - causing picture shaking up and down, and occasionally clicks on the audio. It is well documented on the DS forums, and I have seen it myself - it looks like the image is twitching vertically, but only by one row of pixels. Apparantly its a fault on one of Sky's ad servers.

That aside, it does sound like you have a bad set - the dirty screen effect is not usual on the JVC sets I've seen, and the Sky EPG should be crystal clear. I assume you did try connecting the Sky box directly to the TV SCART to eliminate any external problems with switching? Are you sure the Sky box was connected to a RGB capable SCART? - My JVC has 3 SCARTs, but only 2 are RGB, and text does look poor when connected via a composite input - though the PQ is reasonable, similar to your symptoms.

Stick to your guns with Amazon that the set is faulty. You shouldn't have to pay for the return.

Dear Sparky,

Many thanks I was worried because the CRT days seem over the forum was quiter than of old.

Yep I did try different inputs and the SCART is one of the RGB ones but it does look very like it used to look if I switched the SKY output off RGB on my old set. I have tried every setting I can think of as I was sure it was just a matter of switching a setting re the text problem but no joy. I read another post which said these sets use DIST processing which can mess up a SKY picture pretty severely.

Re the vibration it is much worse on ads so the SKY problem you note is probably at fault.

The killer for me though is the dirty screen issue as it really seems from my reading that is one that is not fixable and it's really bad on this set so I am going for return.

Sent AMAZON a stiff one today with plenty quotes from Sale of Goods Act, a link to Trading Standards Web site and references to 'their reputation in the very competitive Internet sales world' so let's see...

As before if anyone's interested I will keep you up to date?

Don't worry about the DIST processing, your set doesn't have it. Digital Image Scaling Technology is only on the HV models which are capable of 1080i HD.

It's always worth knowing how certain retailers deal with problems like this...

Well well,

Got a call at 09:00 today from Amazon Customer Services, thye were very apologetic and said I wa sent completely the wrong reply when I logged the retrun online and they woiuld of course fully refudn both cost and my postage and the couriers would contact me to arrange a time to pick up the set at my convenience and again no charge. The guy apologised for the mistake several times.

Felt it only fair to them to let all know the update - now I still don't know what to do next any ideas for a decent 28" widescreen CRT???

Hi,

Sounds like the 'dirty screen' effect you mention is down to poor colour purity caused by bad quality control. I had the same problem on two new Toshiba CRTs that I (briefly) owned in 2006. Confirms my suspicion that new CRTs - such as 'supermarket specials' - are built to be 'just good enough' for the undiscerning consumer. I'd recommend 2nd hand from Ebay, where I picked up a great 2004 CRT.

Good news about Amazon - sounds like a genuine mistake as I've always found them to be excellent re returns.

Cheers!

[sparky_paul]

Yep, good to hear that Amazon have sorted it out.

I guess you have gone for a refund rather than a replacement set...

[Brainboy]

yeh Sparky refund which I am told is done in full and carriers come tommorow to pick up no charge - now the real problem finding a decent set!!!

[clemenzina]

How are you getting on, Brainboy? I'm ploughing thru Search here because I want a cheapish 3-scart CRT Widescreen TV and I think that JVC is the only way to go - correct me if I'm wrong, anyone.

I've been hovering over the Amazon one - I'd love to know what eBay seller Matt got his 2004 one from - and what model it was (and whether the courier was willing to cart it up 4 flights of stairs .

Clemenzina,

Not good the search goes on I am seriously considering Sharp LC26P50E LCD as having ditched the JVC (and got a refund from AMAZON) and gone back to my old SONY 50Hz I am now bothered by the flicker - for the first time in my life. I think checking the JVC for PQ must have tuned me in in some way and now I see bad flicker on SKY menus. I would buy a decent CRT but none on ebay yet at a reasonable price - the Sharp LCD looks loads better than most IMO because it's designed for SD broadcasts but I still can't make that LCD leap! ASDA had them and do a 28 day no quible return but they seem to be out of stock!

Why oh why didn't I buy a decent Sony CRT when they were still available!

[clemenzina]

Well... just this evening my mouse* bought a new Sanyo from eBay - it's just a flat widescreen CRT, not refurbished/graded, but it's only got 2 scarts (tho' they're both RGB).

*It wasn't me, honest! I damn' well know that Sanyo isn't the best brand, but at least it's never been out of the box and was only £100. If only I still had my muscly partner I could collect, there are some good second-hand and new bargains going connection-only.

http://tinyurl.com/2s4qrh is the "BuyItNow/BestOffer" one they're still selling, but they also list them with £75 starting price, normal auction, and only charge £15 delivery, they just don't have any on normal auction at the mo.

I don't suppose you are interested in this particular model, but someone else might be.

I'm rambling - good luck Brainboy
