Instruments/tools needed for TV repair

Re: Instruments/tools needed for TV repair

I've always had a DeWALT small hand drill. Very tough and long lasting.

But, recessed screws, as stated above, are a pain sometimes but in my opinion, beats turning a screwdriver 500 times lol

Re: Instruments/tools needed for TV repair

Dumpster diving outside my internship work place (well, more like "Throw this stuff out Tom - anything you see that you like, you can keep.")

Got a cordless black and decker screwdriver with dead NiCds (0V - completely shorted cells.) Just zapped 'em on my 35V supply a few times, charged them with my RC aircraft battery charger (charges anything from lead acid, ni-cd/ni-mh to li-poly), and got them back to life.

More serious recommendations:
- It doesn't really save you much time using one as you spend more time trying to line up the bit on the screw, especially as the device is physically larger.
- Avoid the cheap supermarket/budget brands with 2.4V NiCd batteries. They only give 20-30 minutes operation - or about 2-3 TVs. Inconvenient to run out of charge in the middle of a repair job.
- Also avoid the black and decker ones as they suffer from dead NiCd batteries as outlined above (trick doesn't always work and needs to be done every so often to keep the cells from shorting.)

Re: Instruments/tools needed for TV repair

I would like to purchase a cordless screwdriver which is using Lithium-ion batteries.
I try to keep it under $100.
Which one do you recommend?

Re: Instruments/tools needed for TV repair

That looks great, you will be so happy when you are trying to find out if you still have short circuits or, when it is bad it will light up bright right away. You can prove that by putting a jumper across the filter cap to simulate dead short so you have some idea what it looks like, then try it with working TV or monitor, you will see how the lamp react.
Do you still have that set with the shorted out MOSFET's that you replace twice? You should alo haev some 150Watts and 200 Watts for testing some big TV also.
Nice job.

Re: Instruments/tools needed for TV repair

I'm not that good, but I'm getting better and better. Budm it's awesome for sure and tom66 and all others around here also.
I still have issues with a Vizio VO42L, LG70LG and an Asus MK241H monitor though. I think that Samsung 46A530 finally will be fixed, because the 52" mainboard mod didn't work out as planned. This weekend I'm picking up another one with broken screen for $50.
I still have a Philips, which is completely dead.
Finally I have put together budm's short circuit tester. It came out very nice and compact. One steel box(the ones which goes into the wall), steel cover with switch and wall outlet cut out, wall switch and a wall outlet. The bulb is a plug in style and plugs in in an outlet, the other outlet is for the testing device. One of the side bridges from the outlet I have separated. A TV power cord and one of those clamps with nut on the side of the box and it's all compact and nice.
I will take pictures when I'm home.
One of the monitors (thanks to budm for helping repair it) is set up on one of the benches(IKEA $40 kitchen table ), now I(we) have to repair that Asus to be able to install it on the real workbench. This way I will have two separate work places with two monitors. I can work on two TVs now. Need more help from budm

Have you gotten so good that you dont even have to post to ask for advice? Or just have budm on speed dial? j/j

Re: Instruments/tools needed for TV repair

The market it's getting slightly better. I have six TVs in my garage.

Re: Instruments/tools needed for TV repair

Very interesting follow up on that fluke being relisted a few days later. Some people are nice and understand that people make mistakes and probably didnt leave him bad feedback.

Your right tibikmaki, I havent seen almost any broken sets on craigslist in months, so I agree theres some odd seaonality to the broken set market. Heres to hoping it will be a fun winter. I dont try to agressively to find / buy broken sets though, could post dailys ads saying i buy broken TV's but I dont have time to wade through the emails / crazy people who want to sell their DLP's / crazy people who say they called the repair place and they said fixing the crack in their 55" TV would only be a $200 dollar part. (yet they dont want to invest that 200 into a 2000 dollar tv... )

Re: Instruments/tools needed for TV repair

UNBELIEVABLE!!!! $20 sold for working Fluke 87V.

http://www.ebay.com/itm/330725073380

If the seller meant $200, I wonder if he HAS to sell it for $20?

I folllowed up on this by looking through the feedback. He made a listing mistake and sold the 87V ultimately for $175 about 3 weeks later (easy to tell because he used the same pictures and everything). The original $20 buyer never left any comments (good or bad) so they may have worked out something privately?

Re: Instruments/tools needed for TV repair

Why? Well, in Croatia USED Fluke 87V is 300-350$, a new one is perhaps twice as much. Now, average salary here is 700$/month.

I'm not a Fluke fan boy, but after using almost 15 different makes and models, Fluke earned their reputation as a premium reliable multimeter for a good reason.

The build quality and ability to hold their accuracy is amazing. All my Fluke multimeters are used from all over the world in various conditions. None of them were purchased with any sort of calibration certification, but all of them are within 0.001V of each other. This includes two 20+ year old Flukes (both purchased for $20). The multimeters that have closed case calibration are still running with their original factory calibration settings (you can check the nvram to see how many times it has been calibrated).

I also have many non Fluke brands and 6 out of the 7 are 1% off from the Fluke.

For my present needs, I would NOT pay $500 CDN for a new Fluke 87V, but if I can get one in the $100 range used, I would certainly buy it and sell some of my other Flukes.

Almost got a heart attack when I saw this few minutes ago. Why? Well, in Croatia USED Fluke 87V is 300-350$, a new one is perhaps twice as much. Now, average salary here is 700$/month.

Actually, in this occasion, NOT selling it and NOT sending it to the buyer worth a negative feedback ;-)

Re: Instruments/tools needed for TV repair

Just had this friend of mine build this TV stand. Any ideas for improvements?

[tibimakai]

Re: Instruments/tools needed for TV repair

The microscope's stand it's to small. It's very good if do you want to take very close shots, but you can't use it from a higher position, that's why I have made that simple adapter and now I can use it with my tripod. With the tripod I have the option to move it in any direction.
It would be nice to install it on a workbench lamp(without the lamp) and still using the tripod adjustable part(without the three legs).
The Logitech webcam, has a Right light technology build in, a much better resolution, some kind of auto focus- not a real lens one, just some kind of always in focus technology, but it works well. There is an option to unclick the auto focus feature and it's possible to use the slider manually. I haven't played much with it, just installed it today.
With a regular digital camera it's a hassle to transfer the pictures to the PC.
With the webcam or microscope, the pictures are saved right into a folder.
I was pretty much out to0, because I don't have much to repair.
Bud, this is the way it goes with these repairs? It's a seasonal thing? I can't find almost anything for sale.
The first quarter it was very good. I'm thinking it was the tax money that caused that?
Now, the people are not watching much TV because it's summer?
I'm picking up 22" and up monitors as well, just to do something, because there is not much money in them.
I have just sold an LG today for $80. Picked it up for $35.
What is going on with PainBill? Anybody knows anything?

Re: Instruments/tools needed for TV repair

I did not have a chance to buy that USB microscope you have, I also saw you took the pictures of the board with Logitec, it comes out pretty good, too.
What do you use for your light source?

[cashkennedy]

Re: Instruments/tools needed for TV repair

Before that you just had to hold it? The stand for it looks pretty awesome!

Ive been busy with work for a few weeks, have I missed anything really interesting around here?

[tibimakai]

Re: Instruments/tools needed for TV repair

I made an adapter to my USB microscope, basically two 1/4-20 threads in an Aluminum rod.

Re: Instruments/tools needed for TV repair

Mine is already a 100Hhz for $314 shipped
The only bad thing about it is the noise level of the fan.

[cashkennedy]

Re: Instruments/tools needed for TV repair

Yeah after i posted that i saw that its their entry level scope, so not really anything special about it, can get a LCD one with as many features and so on.
