Re: lg ps8000 vertical lines

As you can see though, the 50H3 board has a sticker on the flash chip with 50H3 firmware, 60H3 has 60H3 firmware. So the board firmware is different.

If you're feeling lucky, you could swap the flash chips over and it would probably sort it out - or you can order a board for a 60H3 panel.

You could also find someone to swap 50H3/60H3 flash chips.

Re: lg ps8000 vertical lines

Wrap board in foil, aside from the chip in question.
Use 350°C moderate air.
Circle around device and push GENTLY on one edge slowly to remove it.
Clean pads with flux cleaner (or isopropanyl 90% or greater)
If all pads are intact I would hand solder chip on.

Re: lg ps8000 vertical lines

ok tom great stuff ill give it ago also is the any parts i could buy to upgrade my station ie solder ends ect

[tom66]

Re: lg ps8000 vertical lines

A tip no wider than 5mm nor smaller than 3mm I find best - circle around the pins while using hot air.

do you have a link for that also link for some good flux and good solder plz tom
many thanks

Re: lg ps8000 vertical lines

Flux - cheap no clean stuff works.
Solder - my favourite is the Multicore stuff but that's quite pricey, any good thin solder will usually work.

Alcohol - http://www.ebay.co.uk/itm/1-X-500ml-...item3cd25a546a

Re: lg ps8000 vertical lines

That is about the level of quality expected from a hot air and soldering station with a two digit price tag...
I had an Aoyue968 which was probably made by the same company, nothing but problems...

i gues so just didnt want to spend loads as still learning and its just a hobby
do you know any gd but cheap ones that would be ok ? just been wacting more of your videos nice work

Re: lg ps8000 vertical lines

Well I can't exactly follow what I preach - my hot air cost me £40.00 but it's at least slightly upgraded chinese junk... DIGITOOL from Farnell. I bought it from a guy on eevblog forums called TopLoser, he occasionally has equipment at very, very reasonable prices.

For soldering I use an ANTEX 690 SD... excellent 65W element, really stable temperature -- second only really to a Metcal... RRP around £200 or approximately £0 when my boss was cleaning out the old gear .

For occasional work it's fine, just don't expect high reliability stuff for that low price. I got so frustrated with mine (my one before the DIGITOOL, the AOYUE 968) because after 2 years use I had:

- two hot air element failures, one nearly setting the gun on fire (flames were coming out of the end!)
- one soldering iron element failure
- endless problems with random display lock up, ERR, showing 530C (for temp all the time) etc.
- loud buzzing noise continuously when NOT in use
- pump vibrations randomly making entire unit shake across the desk

...I paid £139 for that and it was the worst £139 I have ever spent.... NEVER AGAIN!!!

Re: lg ps8000 vertical lines

ok so what should i buy lol im waiting for them to email me bk as i cant use it now

[tom66]

Re: lg ps8000 vertical lines

As I said, if you only use the unit occasionally, that's probably adequate for you, just don't expect high reliability.

If you come to depend on your tools, you're wanting to look at the £250 to £500 range, units like Hakko, which are high quality Japanese designed...

But that's an awful lot of money to spend on a hobby.

Re: lg ps8000 vertical lines

ok cheers tom i might be getting a weller soldering iron like this http://www.ebay.co.uk/itm/Weller-PS-...item257efc2376

only alot cheaper of a frend so that should be better ? what tips should i buy if i do get that could you put link for the tips that will fit when you have time cheers

[tom66]

Re: lg ps8000 vertical lines

That's not really anything special, as it doesn't appear to have an adjustable tip temperature which is fairly essential with modern electronics (especially surface mount, but also when mixing lead free and leaded, or when using the soldering iron to shrink heatshrink tubing.)

I'd only get it if it was really cheap (like £20 or less.)

It's also not got a hot air gun which you would need for the occasional job like this LG ctrl board.

Tips, I'd get a chisel tip and a pointed tip, no need for any others.
