LG Model 26LX2D LCD TV, Dead

Compaq and HP desktop computahs are full of T10 screw heads on 6-32 screws. Just about everything else is Philips. The most common screws in desktops are 6-32 with a combination 1/4" hex and Philips drive, and M3 screws with just the Philips head. The larger 6-32 works well with electric screwdrivers. The small M3 will get stripped out quite easily. Since both will fit a #2 Philips bit, the temptation to use it on the smaller screws is just too much.

Nope. 6-32 will mostly work. By mostly, I mean into anything that is

By smaller, I mean the M3 computer case screws and the M2, M2.5, and M3 laptop screws. For M2 and M2.5, there's just not enough metal in the head to survive. In addition, they tend to be recessed below the laptop surface, making it very difficult to extract when stripped. However, stripping the head is not the most common failure mode. It's cracking the plastic mount supporting the threaded brass insert. That's even more difficult to repair, as it usually requires complete disassembly and glue.

Maybe when commodity electric driver/screwdriver torque limiters are marked and calibrated in inch-lbs or Newton-meters, like any good industrial pneumatic screwdriver, I might feel a little better about using one.

Hi Jim and Everyone,

UPDATE:

Several electroylitics on the PSU board, especially low voltage types, have higher than normal ESR.

I gave an estimate for this repair, but my customer declined to have it repaired.

Again, Thanks to Everyone, John

This site was offline during the last couple of days ...

I realise that you have already found your manual but, FWIW, I expect that the 32LX2D model may be similar ...

BTW, the above site is an excellent resource, especially for LG service manuals (Australian market).

John. Can I just ask for the future, that you post your replies at the bottom of the existing content, as is accepted usenet practice, rather than at the top as you would conventionally do with emails. Top posting, especially when the greater majority are sticking by the bottom posting convention, makes the thread very difficult to follow in terms of what's been said by whom, and when.

Thanks
