Sharp LC-40LE810UN question

Re: Sharp LC-40LE810UN question

Well, the power supply was probably fixable... I suspect you could have additional damage to the TV due to water.

Re: Sharp LC-40LE810UN question

I have no idea.
I have just purchased the power supply.

Re: Sharp LC-40LE810UN question

Why is the tuner can rusted? Has this TV been exposed to water?

Re: Sharp LC-40LE810UN question

We can't move to the mainboard.
I have/had the voltages, but the 13V did not reach the connector.
At the connector I had only the 5.5V.
After a couple of minutes of measuring, the voltages are gone again.
I have tried it again after a while and it was back again for a couple of seconds and then drops to 0.7-0.8V.
I'm so pissed on this power supply, that I'm thinking of just buying another board and be over with.
I can have a short or something in the secondary and the feedback kills the power source?

I have made some pictures, not the greatest ones, specially the bottom one:

No, I just saw the video and thought it is the same as yours, I already have 3 Tektronix scopes at home.

Re: Sharp LC-40LE810UN question

No, it's got the same fan. Scopes are identical hardware wise. It just doesn't bother me much...

Re: Sharp LC-40LE810UN question

I will a bit later.
Bud, you are thinking about getting this scope?
Tom, how come your doesn't have a noisy fan? 1102 has a different one then the 1052? Everybody complains about the fan noise.

Re: Sharp LC-40LE810UN question

Post some pictures of it.

Re: Sharp LC-40LE810UN question

What should I check on the mainboard?

[tom66]

Re: Sharp LC-40LE810UN question

PSU is fine, for now. Check main board. Maybe TV was hit with a surge.

[tibimakai]

Re: Sharp LC-40LE810UN question

Do you guys think that I should still check the 18V at the start up, since I have the output voltages?

[tom66]

Re: Sharp LC-40LE810UN question

No fan noise problem here. It's quieter than my old HP 54501A.

[tibimakai]

Re: Sharp LC-40LE810UN question

I can say now, that I have a 1102E
The fan noise bothers you?
I don't even hear it because I have a 20" fan and a small Tornado type fan running all the time.
When the warranty it's over, then I will replace the fan with a quite one.

Re: Sharp LC-40LE810UN question

My 1102E cost a little bit more, but only because I'm a scardy-cat and don't want to brick it by doing the upgrade wrong.

Re: Sharp LC-40LE810UN question

Yes, I have 5.55V and 13.7V.
Yes I have the little one in the video, Rigol 1052 which became a 100MHZ scope with a mod. I picked it up from Rigol for $315 shipped. They had a bit of questioner and I have got some discount with that also.
Hardware wise is the same as Tom's 1102 though. The difference is all in the software.

Re: Sharp LC-40LE810UN question

So you do get voltages on those 16V caps in post 43 now?
By the way, is this the scope you bought?

I think he's got the DS1052E a 50 MHz scope, modded to 100 MHz. I can highly recommend the DS1102E myself as I have one.

Re: Sharp LC-40LE810UN question

Next step I have to take pictures with the mainboard, right?
