LCD repair education.

(1/5) > >>

OldLes:
It is thirty odd years since I took up TV repair, when I generally educated myself by reading Television magazine. I had "played around" with stuff for years (first Xtal set built in 1954), so it was not too difficult at that time. Twenty years ago, again with the help of Television, I (sort of) mastered CD repair. Then circumstances had me working with computers (hardware, NOT software) and the electronic repair side was left behind. Seven years since retirement, I have played about with the odd LCD set, but I don't have any real ideas about servicing them the way I did with TV and CD. I get the impression manufacturers either replace the lot, or sometimes a complete panel. I would much prefer to get back to component level, but I obviously need to re-educate myself. Where do I start? No TV mag today, so how do I learn this confusing technology? Advice please, OldLes.

Have you tried reading service manuals? Start with an older model, always best as it will explain the basics much better, then work your way through them. I'd also recommend  getting a working set & figuring out what each bit does & why.

You know what goes faulty, how to measure & what each fault would show itself symptom wise. It's also a good idea when you get a faulty set trying.to diagnose the fault before posting for.help. I can certainly help you if you're serious about this.

Hi Andy, thanks for reply. I guess if I search around here there will be manuals I can look at. Can you suggest an "older model with better explanation of basics" which I can download?
What are Philips manuals like, as I have a Philips Model 32 PF 3320 / 10 which I can play with. It has a smashed screen, but I think I may be able to find my way through the tuning menu by looking at the instruction book, and get it tuned in. If I get just enough picture to be convinced, and sound, I can then get some ideas from a working chassis. I also have a 26" JVC with scrap screen, but enough viewable to make sense from, but I hope to find a new screen for that so I have a digital set in the bedroom to keep SWMBO occupied whilst I am down here reading LCD manuals.
My first serious task, when I get a better idea of modern sets, is the TCM which I listed in the manuals forum.
Jordan has sent some manuals for that, but not all are suitable. Of course, they may be sufficient once I know where to start!

You don't need to see whats on the screen, you need it working so you can read voltages.

What are they in stand by, what goes to the t-conn, the inverter, can you disconnect something & the set stay on?

We used to.produce a small monthly magazine for a short time, we stopped as no one read it. I'll send you.some pdfs when I find them, it will help.
