Belinea 102035W Help

[Andeh]

Ok, first of all, I'm new here, so hello everyone.

My problem, from what i've gathered, is relatively common, and im sure most of the regulars here will be able to help me out here.

I have a Belinea 102035W 20'1" monitor, and about a year ago it began to display signs of failing capacitors on the power board.

If there is a signal going into the display, and I switch it on, the display will power up, for about 2 or 3 seconds, show nothing on the screen, and the blue power light will begin to flicker on and off in a strobe fashion, before losing power altogether.
The only way I can get the display to power on again, is to remove the plug for about 10 seconds, to allow all the power to discharge, then plug it in again.

So far the only way to get the display to work, is to switch it on, with no input signal, leave it for about 30 seconds, untill it the blue light turns orange, and it goes into standby mode, and then repeat this process for about 10 mins. I am guessing the caps need to be warmed up first before the display will actually work.
After doing this for around 10 mins, I can then turn on the computer, and the display will work fine.

Here are some pics of the displays power board, and a pic of the only cap I can see that is showing signs of failure:







Any information on the best route to fixing this display would be greatly appreciated.

Cheers.
Andy.

Spend the ten bucks on good quality capacitors and go from there.

Looks like seven capacitors,you can leave the big alone.

Re: Belinea 102035W Help

yeah, I've already looked around, and the capacitor I need is a 1000uf 16v, which I can get on ebay. I'll sort one out next week, after I fine my soldering iron.

Re: Belinea 102035W Help

I would replace all of them except the large one,It looks like seven.
Ask and find out what series of capacitors you are getting.
I do not know about some of the Ebay caps be careful.

Re: Belinea 102035W Help

RS components and Farnell seem to be the main distributors in the UK. Many members recommend Panasonic FM or FC series caps for best results. Do as alexannsa suggested and replace all except for the large cap. The ones nearest the heatsink have been exposed to a lot of heat because of the poor design.

Andeh,
Go to http://www.esr.co.uk/components/......Look for the 105 degree range,and they will do you I suspect.Farnell have a Minimum order value of £20 plus Vat.

Re: Belinea 102035W Help

well, I had a look at the RS components website, and they seem to have all the caps I need. It will cost me just under £10. I feel a bit stupid, but I can't get my head around the esr website. If you're willing to help me out, I can list the caps on power board, and you can pick out the ones i need for me

Re: Belinea 102035W Help

At esr, just download the Catalogue,from top right,page 8,green caps,105degress,radial,and select by uF and Voltager. ring them,and should cost you less than £5 which includes the £2.50 P&P for what you want.

Re: Belinea 102035W Help

Ok, ive placed my order with esr.co.uk. it should cost me £3.69 for 7 capacitors. Thats pretty cheap!

Re: Belinea 102035W Help

Ok I have a problem now. It appears I overlooked the other 2 circuit boards in this monitor (don't ask how, I honestly don't know)

I have no idea what these 2 boards do, but i'm sure most of you here will know exactly what they are, and what problems they can cause.

After inspecting these 2 boards, I have found a total of 7 bad capacitors. I can replace them, but it's going to have to be put on hold for 2 weeks untill I can find some spare money to buy them.

Re: Belinea 102035W Help

The first board is the logic board, and man it looks ugly. Definitely replace those as dirty power going to the logic board could kill the processor. Although unlikely, better safe than sorry. The other board is the inverter board, and it could well be the source of your backlight issues.

Okay, I should of mentioned this before, but I let it go.

Took a quick look at this site and it looks like the caps are some off brand, 105 deg C, general purpose caps. Not the high ripple, low-esr caps that members here recommend. You did save money, but it looks like you didn't do yourself any favors.

its ok. out of those caps I ordered, I only intend to use one of them. Infact, having said that, when I come to order the other 7 I need, I might just order the extra one.

I advised him to buy those caps.I have used them for the last 3 years, with no returns,and no failures.In my limited experience,Very low esr caps,which are also available from this Manufacturer,via the UK distributor Anglia,are necessary,in some cases BUT not in every position,and i had no qualms at all in advising him to purchase them.

Re: Belinea 102035W Help

To be honest, I don't mind using the cheapest caps I can find, as long as they work. If I can get a few extra months out of this monitor, i'll be happy.

Re: Belinea 102035W Help

Good news. Replaced the caps, and it powers up like normal now

Really is a nice monitor when its running fine.

I suprised myself with how clean my soldering was, I'm not an expert with a soldering iron, but my joints looked just like the joins already present on the board.

I am a happy bunny
