Philips 37PFL4606H TV: Foggy Image & Moisture Exposure - Locating Fault & Solutions

Hello, I have a problem with the Philips 37PFL4606H TV - the image is foggy, please help me locate the fault. I was looking for a matrix in the logic, but there are no damages, there are no scales. However, it is worrying that the TV was exposed to moisture or flooded, below I put pictures.

Rather, it's logic. Maybe I'm wrong but you did not give enough (some measurements).

When it comes to measurements, I would ask you for help, where to measure and where to look for possible damage?

On this forum, 20 topics were written about 37PFL4606H /? (58/60/12) for chassis TPM7.1E LA and in one Link it states that there is a matrix
37PFL4606H - 125 - LG370WUY SCA1 (or equivalent to LC370WUG)

Also given what : main and power supply.
-eg. PSU 715G4546-P03-H20-003U / 715G4546-P02-H20-003E (4606H / 50)
- e.g. main 715G4481-M03-000-005X / 715G4481-M02-000-005B (as above)
- SoC MediaTek MT5395LUGJ System-On-Chip (SOC) TV Processor
* T-con on main
• MAX17113ET Multi DC / DC
• MAX9668ETP GAMMA Link_ datasheet
• TPS65192RHDR Level shifter

Give your set.

Rather damage on this small matrix plate (ears)
- look carefully under the magnifying glass flex tape ( without drips, dampness)
- this last picture does not look interesting

 

 

Generally speaking about the fog in LCD

Quote:

Gamma - gray scale correction.
 It is necessary to create nonlinearities in the area of dark tones for a more correct perception of people's eyes, ... is more sensitive to changes in the dark. This is the nature to do, and the plate's constructors take it into account.
... this nonlinearity is changed into a bright area, so we see a fog.

It is generally about V-Com, VGMA_REF, AVDD, ...

In my opinion, the matrix to the basket unfortunately.

But fancy!
One sees something as if through a fog, on the logic of the matrix there are no scales, others can not see anything, and they will tell you until it is full of dust.

Lisek, a service tool for this model is generally available. if someone can not use it, your pictures (unaware) will not help.

Tiaaaaa, the guests go crazy, the measurements, the blinds, and the liquid of the żreru.

Hi again, will the replacement of the matrix repair the TV?

Is unknown.

Give me a matrix !?

Like matrix with "ears" is rather like this.
But this price!
Statistics says 50:50
  (' ') That's just because without measurements on the system. T-con on the motherboard.

* same "ears" (6870S-0962A and 6870S-0963A ...) in China is about 30 yuan (1yuan = 0.15 $ / only RC elements), unfortunately the cost is irritated by the re-soldering of flex bands to the die.

You can unscrew the tapes one by one from the ears and see, for example, what will happen.
* measure voltages with on / off. tape
* measure Vcom voltage (approx. 7V) / V2-V5 and V10-V13 at MAX9668

Ah! So now they are ears? And those from the first quote? Tortellini?
Who unlocked this bastard?

Show where it was written (once ears> once ears), exactly.
I look and do not see.

Fox? Are you making a fool or myself?
Is it so hard to look at quotes?
I ask you, freaked out, when what did you mean?
Because I understand that you have seen the pictures (the text you do not read in its entirety, it's been known for a long time) and the 'ears' that you write about

You must have seen!
So once again I ask what you mean in this passage

I presume for side ones (if any).
So if the upper (lower) ears are, then the side ones have to be called the ears. To know what's going on!

So dear readers, we have a new name for these tiles on the bottom or top of the matrix - these are the ears!

6870S-0962A and 6870S-0963A
They are left and right.

Ot and the whole secret.

Gently purge these raids, maybe you will see something more, under the magnifying glass of course or other magnifying device.
