Re: LC60LE830E Error Lamp,No control
Hello.
I will tell you that the TV has been working well for about 9 days.
Usually, I give a true follow-up of the fault solved, but this case is so weird and out of the ordinary that it should not interest anyone.
I cleaned the pins of the connector going to the infrared detector of the remote control on the circuit board of the tactile keyboard, the TV then restarted by simply reconnecting the tactile keyboard on this one.
the keyboard works perfectly but I have never managed to enter service mode.
I have...

Re: LC60LE830E Error Lamp,No control
Hello
Again, new.
I replaced the 4 ramps backlight.
the LED bars are fixed 2 by 2 to an aluminum bar.
There is only one broken down but it was easier.
It was late and I wanted to do it quickly.
I put the one of 60le635.
I will repair them later when I take care of the 60le635.
For the dismantling of the slab, I did an experiment.
For fear of breaking the lcd slab, I laid the slab flat on a rigid board
and I dismantled all the screws fixing the back panel of the tv to the front...Leave a comment:

Re: LC60LE830E Error Lamp,No control
Hello ,
More news ..
Thanks to my tests on the L1 connector of the power supply DPS-183BP-3A and the anomaly found on the LED2 strip, I decided to connect the socket of the L1 connector of the 60 LE830 to the backlight wires of the 60LE635 I know good and similar.
By this test, I wanted to make sure that the repair of my backlight was one of the solutions to get to repair my Sharp TV.
At the start of the tv by the Power button plus the connection of the power cable, Jai at the beginning the same symptome as...Leave a comment:

Hello again
For Budm
I will give pictures of the different cards.
But you already sent me the diagram of the electrical power supply which is a DPS-183BP-3a.

The schema is from the site.
I put pictures of the electronic cards on my second messages page 1 of the site.

Re: LC60LE830E Error Lamp,No control
Hello
With the 60le635 keypad, the power supply is woken up with 1 single press on power or the V + key and connecting the power supply.
V- and (Imput) and power connection gives nothing.
Probably a problem of interpretation of key sequence, it is not the right keyboard, it could explain.
you can not really know what the motherboard comprises.
But it wakes up the cards for a cycle of about 35 seconds.
I tried to disconnect the lcd tablecloths on the TCon board.
I tried without the white...Leave a comment:

Re: LC60LE830E Error Lamp,No control
Hello,
I have something new.
I confirm the failure of the touch control panel.
But before, I have to explain some observation.
After having observed the RC connector on the main board, I could realize similarity in the electronic architecture with different TV sharp.
I also have a lc60le635 with a breakdown on ur13V.
The mainboard differs by the additional soldering of electronic components and programatiosn different circuits between the two models of TV.
But the circuit board is identical between...Leave a comment:

Re: LC60LE830E Error Lamp,No control
Hello ,
Hard to say the original problem of the TV, but I can say that all the son of the backlight connector had to be tested before I get the TV.
The insulating contour of the wires has been cut slightly to make electrical measurements on the supply of the led strips.
I wonder ?
I would have to test the led strips.
If there are any defectives, the repetition of 5 errors on the original motherboard and on the new motherboard could have caused their blockages.
The simple fact that the touch keyboard may...Leave a comment:

Re: LC60LE830E Error Lamp,No control
thank you for helping me
I made several combinations, all disconnected A A 'B B', I also tried to wait a moment with unplugged sector, reset again the defects with each manipulation, but nothing happens.
I then unplugged the white connector at the top right and still did some tests
it remains the same, the motherboard remains silent and refuses to return ps-on.
The tests that you make me do they are similar to this video.

Hello everyone
I have something new.
I buy a new motherboard F733WE51.
So I installed it today.
I plug the TV and it starts, all the lights on the control panel come on and after 10 ... 15 sec, an image appears with marked (no signal detected or imput), then the TV goes off again and the chevron starts blinking in a cycle of 1 time and pause. 1 time break.
Remote menu button indicates 1 long 1 short.

Re: LC60LE830E Error Lamp,No control
Hello
Bad news for me.
My PHilips PM3055 oscillograph just broke down
I had changed all the electrochemical capacitors of the power supply and THT circuit there are a few months to give it a boost ^^
It worked very well but a piece just broke and my electronic supplier does not have any, the stock is exhausted everywhere.
I find nothing on the net for the reference.
This is the triple THT which is short circuited.
By stripping the THT wire that goes to the tripler, the power supply does...Leave a comment:

Re: LC60LE830E Error Lamp,No control
Hello everyone.
For R J
Thank you for your detailed explanation, I made the last test of the power supply card.
PNL12v works well too.
I am now almost 100% sure there are no problems on this map.
Moreover, AC-det is well generated when you activate PS-ON
It is then about 3.3 volts.
The only thing unverified and the activation of the backlight panel.

Re: artefacts Lg60PZ550
Hello Daniel
In view of your video, it is not a problem of ZSus.
But, Something really makes time to settle in the TV.
It would be necessary to seek at the level of the regulation of the various tensions.
Did you gently tap the cards to see if your electrical contact was good?
Check welds on different capacitors, regulators and all that can heat.
Also check all the welds on the connectors of the different cards, also verify that the supply voltage is on the control board and does not vary at start-up....Leave a comment:

Re: artefacts Lg60PZ550
Hello
I thought from the beginning to a failure of the ZSus card.
But, I'm not sure now.
Since the new settings, the picture comes quickly?
Does it take the entire width of the screen or a dark area at boot time?
In case it is defective, there is a repair kit but it is suitable in the case of a cut fuse and short-circuit mosfet transistors
The state of the electronic welds should be carefully checked.
on the Zsus card and the Ysus card

Re: LC60LE830E Error Lamp,No control
Hello.
Thank you for this additional information R J
I'll do some checks and test pnl12v. I will connect together
PS-on and PNL-POW whit BU5V
Of course with the PD connector of the power supply board unplugged.
For Budm.
the test you had made me, it is used to determine if the mainboard wakes up.
If it's negative like in my case,does this in your opinion confirm that the problem is on the mainboard?

Re: artefacts Lg60PZ550
Hello
Ok, so the fuse is not cut.
What can you find on the P102 connector.
The voltages are shown on the printed map, I am using a photo found on the web to try to help you.
Sorry to say but Z card photos are unusable.
There is a connector at the bottom of your card but we can not see anything exploitable.
Can you tell me if your fault is similar to the video link?

Re: artefacts Lg60PZ550
Hello
Check the fuse on the ZSUS board
Please, I can not read the reference of the ZSUS card.
You must read the reference on the picture you posted, if you can not, I can not see that either.
You must have an EAX type reference .............
Please try again a clearer picture of the zsus.
SInon, the measurement values are in accordance with the label of the panel

Re: LC60LE830E Error Lamp,No control
Hello again.
The TV test with the modification has unfortunately not given anything new.
With the resistance of 1 k, the conductor wire AC-det = 4 volts. its good .
But there is still no return PS-on in the mainboard.

Hello
Thank you for your budm scheme.
It's the same as my TV, it's not close ..
She is identical.
Congratulation !!
My card is a DPS-183BP 3A like the one sent in link.
This is going to help me a lot by the ac det error.
I go back to work doing what you told me.

Re: LC60LE830E Error Lamp,No control
Hello .
Sorry, that's what I want to do.
But google translation has changed the meaning of my phrasing
This is the only wire ac DEt that I removed on the power supply side and connect it with a resistance of 1K to 5volt (Bu5V)
the pd connector will stay in place.
