Pioneer Kuro PDP-LX5090 7 blinks intermittent

[tom66]

I am picking this up. I'm paying a lot of money, way more than usual (£225) but I think it is worth it given it is a 9G Kuro. 50" 1080p. The "Best" TV ever made only beaten by the 9.5G Kuro before Pio gave up the ghost. No TV has ever matched Kuro contrast, black level or brightness. It will most definitely be going up on my wall. I cannot sell this!!

Anyway, I am just wondering if anyone knows much about the 8 blinks of death on these. IIC comm fault. It's intermittent, the set will power up now and then. I'm thinking there's a good chance it's a bad linear regulator, as the IIC (I2C, eye-squared-cee) bus is powered by a 5V->3.3V linear regulator. I've seen someone do a PRO-series Kuro (I think that's 9.5G) with the same fault. Would be nice.

Sorry PZ80, you will be ousted by this Kuro!

Pure plasma pornography...

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

After doing a little research. Someone else had the same issue and eventually stopped turning on completely. They replaced the audio input board and it corrected their issue. So I would look for faults there first.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Funny, seller is giving me an IO_AUDIO board that was ordered for this fault but never installed. I think that's the same board and the I2C bus does cross mostly onto that board.

That would be the world's easiest repair. Not quite, I think the loose LVDS on the 46" PZ80 was easiest. But I still want to figure out exactly what the fault is...

Wow that would be awesome. Post a picture of it when u get it. I have never seen or heard of that tv

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

I don't think a photo can even attempt to capture how good these panels look, especially if properly calibrated. I've seen one in person a few years back at a friend's house (it might have been an 8G, I'm not sure, but it was a Kuro), but didn't think much then. Wasn't really fascinated with TV tech like I am now...

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Very true. What year is that from. Does it have the double glass plasma screen. I haven't swapped my panasonic plasma with any of the tv's I have fixed yet because of that strong screen. I have accidentally thrown a poker chip at it and it did t even scratch it. Cause with kids screen protection is my major worry.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

It's 2009. Panasonic and Samsung in 2014 have just managed to achieve Kuro 9.5G black levels but the brightness is still too low due to energy saving. Kuro is truly reference quality. Pretty much the only thing to beat it would be an OLED... but I don't want a curved screen and don't quite have £10k lying around to blow on a TV so will probably wait for it to become much cheaper.

No double glass. The filter is bonded straight to the panel to minimise reflections. I don't, and probably won't ever have kids (meh... maybe in 10 years), so that's not a problem for me.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Very true. Nice tv. I will have to keep my eye out for one.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Hey quick question while your here. Can u check out my thread about my westinghouse end of line resistor thread. Is it ok for the tv to turn on as soon as it's pluged into the wall outlet

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Budm is doing a good job, I will chime in if I have anything extra to add. It can be confusing for two to try helping at the same time.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

That's true. Thanks.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Anyway, I am picking it up Wednesday, so I will report back then.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

How much is that converted to usd

[tom66]

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Nearly $400 USD. Used, they are worth about 4x as much. That is about my ratio for how much I pay for a TV (including parts) vs what I sell one for. But sometimes I keep them... like this one.

[audiofreak19]

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Wow I have never spent that much. Most I have spent so far was 150 and 50 in parts and learned a lesson from it about how to tell if a led panel is bad lol.

[tom66]

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

I can see this one powered up though, so there is less risk in getting a dud panel.

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

Nice! Cannot wait to see your fix on this machine!

What do you think of the older Pro-1110HD ?

[tom66]

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

It's ancient, 2004, no better than e.g. a Panasonic 50PX600U. Decently made, and a good picture, but nothing at all comparable to a Kuro. Black level will be LCD-like but it will still benefit from plasma panel technology (very bright whites, good contrast between pixels and white to black, high motion responsiveness, good colour gamut.)

Re: Pioneer Kuro PDP-LX5090 7 blinks intermittent

I know that was their flagship 15k price tag set in 2004, someone offered me one for nothing it doesn't turn on. I think I will pass.

I been looking for a cheap Kuro for awhile now heh, I have seen a few local but they go very quick.
