Blaupunkt 32/1471-gb TV - No Picture Issue, Voltages 12V 42V 5V, Troubleshooting Tips

Question

No picture is a weapon. The voltages are 12v 42v and 5v. What else can I check?

mirex · Answer

Please describe exactly what is in the pictures! Good! I don't know what these symbols are.

stiff12 · Answer

First sentence phone keypad error, sorry. Pictures show the motherboard.
These symbols are the tensions that have been measured. In the second picture you can see the overheated luck and also in the third one. In the third picture there is a voltage of 42 V.
How to check the matrix backlight?

mirex · Answer

Can you read comprehension? Is it not really? I can see what the pictures show. But I will not waste my time and destroy my eyesight, what is written on these pictures! Please write in letters! Complete with this TV. No, the voltage symbol has a slightly different letter. Normally. 1000 topics have already been about this.

It's best to check quickly ... strange question for electronics.

stiff12 · Answer

Sorry, gentlemen, but TV is not my great passion. I have a question whether the transformer from the second picture with a thin double cable is the backlight to the matrix?

stiff12 · Answer

At the request of mirex I provide the data exactly: Model No 32H2HD Serial No 311060052 LVW32055DX E2 V1 MADE IN CHINA

mirex · Answer

It's still not that!
What is this album ?? It says there!
Plus full data from the sticker on the casing - model, product, serial.
Letters.

And it's best to have someone fix it, because you get nothing and nothing.

stiff12 · Answer

Well, I gave it to a repair facility and the guest says let it go. Model 32/1471 / GB-5B-HBKUP-EW Motherboard: TP.MSD309.BP85

GanCegall · Answer

Household appliances, washing machines I understand, but electronics? You can't distinguish numbers from letters: Look again if that's how it is: then as recommended:

stiff12 · Answer

I'll drive over there tomorrow and take a picture. The one who passed it has poor eyesight.

stiff12 · Answer

I send better photos. The element under the heat sink was also replaced, which smudged brown (Mosfet JCS7N65FB). Unfortunately, the element did not change anything. I do not repair the tv, but I think that the matrix backlight is a problem, will you help me check? Please kindly.

stiff12 · Answer

I found a fault on the strips, one LED is off. Connected in series? How can you fix the above-mentioned fault? All the slats right?

mirex · Answer

Added after 4 [minutes]: You have the equipment on the table, and you ask us, how are they connected? A rhetorical question on the forum with the level of knowledge and possibilities presented?

stiff12 · Answer

Serial connections. My knowledge is in a different specialization, but I still want to expand it.
I am only asking for guidance in the above-mentioned problem and help from specialists, and there are such people on this forum.
I have already used the fishing rod, I have a fish, now I am asking how to frame it? Thank you in advance.
I highlighted the LEDs separately, one on the strip is damaged.

mirex · Answer

Then maybe learn to read comprehension first, and then make the requests. ;)

You already got the answer to the last "problem". ;)

And if it does not satisfy you because of costs, for example, dozens of topics are already on the forum. Just read.

stiff12 · Answer

The slats are replaced and the problem is solved. Best regards. Although the fish was hard to frame.
