Freecycle is a community oriented setup, usually based on Yahoo! Groups that only allows free transactions. But about half the postings are for requests.

Yeah, and the other half is for furniture... Local auction sites are the best bet usually.

Re: HP lcd L1502 15"

I will have to check out the recyclers around my town. There is not much on craigslist in my area.

I am not familiar with kijiji or freecycle. Are those just websites?

Google is your friend. Kijiji is eBay's answer to Craigslist. Freecycle is a community oriented setup, usually based on Yahoo! Groups that only allows free transactions. But about half the postings are for requests.

Samsung's and LG's mostly die from bad caps. those are usually the easiest to fix.
Especially the 22" Samsungs (T220, 2233BW, 225BW, 226BW etc. ..)

those are a good start. they're pretty common and there are quite a few threads on here

:/ school made us buy tablets. Its what they call "paperless campus". They make you buy the pc then they charge a student arm and a leg for the maintenance and repairs.

Craigslist, Freecycle, Kijiji, recyclers.

I was looking for some big screens online, but they go for too much. Any suggestions where I can pick some up?

Re: HP lcd L1502 15"

Good job... Next time look for a bigger screen to fix.

A very good suggestion. I'm using a 23" KDS wide screen monitor that cost me about $20 - $15 for the non-working monitor and $5 for the caps to fix it. With a little judicious use of your time you could be using a much larger monitor and have made money on the upgrade!

Re: HP lcd L1502 15"

Hello Everyone!

Today I received my C5707 transistors. I went ahead and solderd them in and as you can see on the picture I am using my fixed and working monitor to post the update

I changed only one set of C5707's and resoldered the other two. I also resoldered all the transformers. Hopefully this monitor will last me another few years

I am a college student, so I try to save any way I can. I just wanted to say thank you to everyone who helped me fix my monitor (retiredcaps, plainbill, th3, kaboom, alexanna and steve2). I would not be able to do it without you guys. I have learned few things about electronics along the way. So thank you guys again!! You helped me save some money!

sincerely,
leo

Re: HP lcd L1502 15"

I just tried testing it in circuit and it read 0.3 ohms. So I think it is good. Thank you Retiredcaps!

Re: HP lcd L1502 15"

Is it ok to test it soldered in?

Any type of ohms measurement is always done with power off and device unplugged.

Yes, you can measure the picofuse "in circuit" aka soldered in.

Re: HP lcd L1502 15"

Some Benq boards have bad c5707, picofuse, and fu9024. Your board doesn't appear to have the fu9024.

You can test your picofuse to see if it is open or not. A good fuse should measure less than 1.0 ohms.

Re: HP lcd L1502 15"

it was actually a fuse, not resistor.

Re: HP lcd L1502 15"

Yes.

KSD1691GS

Works fine. 512-KSD1691GS at Mouser. They are TO-126.

Replace ALL caps and resolder inverter board around transformers, tuning caps, brightness PWM and AC inlet, as well as any other cracks you see.

Thanks Paul. Now my next step is buying transistors. I will let everyone know about my results.

Re: HP lcd L1502 15"

Does anyone know what other transistors can be used in place of C5707?

Yes.

Re: HP lcd L1502 15"

ebay.com. Search for c5707. I got mine from "sort by lowest price + shipping" and they work fine.

I have seen some repair kits on ebay. They include some additional resistor. I remember reading here on the forum something about changing it, but it might have been on the dell monitor. Do you think I will need to do that?

Re: HP lcd L1502 15"

Thank you guys. You have been very helpful and I feel like I am learning a lot!
