Re: LG Flatron M237WD - After approx. 30 minutes the backlight goes off




The hottest one is the number four. The only replacement I found here has the most similar parameters to others.[url]http://www.ame.cz/Trafo-inverteru-CCFL-podsviceni-KP0093A-F-KP0093AF-_d138152_10699.aspx[/url]

place: 0,19mH
has: 0,16mH
versus measured: 0,05mH

I write after the exchange and the test. PaulRe: LG Flatron M237WD - After approx... is the number...

Re: LG Flatron M237WD - After approx. 30 minutes the backlight goes off



I do not know. I try....

Have a nice day.
First of all I want to point out that English is not my language. Thank you for your understanding and apologize for my mistakes.
As I wrote in the title - After approx. 30 minutes the backlight goes off.
Television has already been repaired by somebody before me. Soldering was not its strong side.
After the measurements are at both 5V and 15V sources.
Exactly. 5.1V and 15.2V. I decided to measure some of the components.
See marking numbers on the image.
I measured the QS2015 tester ([url]https://www.buyincoins.com/item/68729.html[/url])....

Re: Vestel MB '17MB82S' unknown component.



Hi, replacing the IADUE - TV circuit already sounds.
The TV was in standby for about 10 hours. When the TV is turned on, only the backlight is on. After 5 minutes, the image also appeared.
The woman turned on the TV, so I do not know if the LED was on standby.
Probably a problem with some tension.
Thanks for any help. Paul ...

Re: Vestel MB '17MB82S' unknown component.

Hello,
The TV did not turn on. Turns - work led backlight. Voltage on board 17IPS71 - OK. Board 17MB82S see the damage. Attached photo. According to the forum, it was replaced with a 0 Ohm resistor. The TV picture is already going, but there is no sound. I measured the voltage on the points board.
5V_STBY - TP3 - measured 5.19V
3V3_STBY - TP4 - Measured 3,30V
12V_VCC -TP12 - measured 12.43V
VDD_Lineout - TP24 - measured 11.82V
5V_VCC - TP13 - measured 5.18V
3V3_AVCC - TP15 - measured 3.21...

Re: Vestel MB '17MB82S' unknown component.



Hello, I have also given 0 ohm resistor. Tv already works, but there is no sound. Surely there will be the same problem with the power supply. Link from page 52. I do not know where to find you please advise. Thanks, Paul...
