Re: Identifying backlight LED
Hi
Thanks for your message
The led is 4mm x 3mm
There are 20 leds in series. So 30V / 20 = 1,5v?
Thanks for the link. There they are really expensive. I would like to buy them from my local electronics dealer.
Greetings

Identifying backlight LED
Hi
i got a Blaupunkt 40/233I tv with a broken backlight.
I disassembled the tv and looked for bad caps but they are ok. The backlight connector delivers ~30V under load
So I disassembled the panel and found 2 broken leds on the led stripes.
Can you help me to find the correct package and correct values?...

Eton EC 500.4 car amplifier - mosfet up in smoke
Hi everybody,
i got a problem with my car stereo. I use a Eton EC 500.4. Today it stopped working.
I disassembled it and found this:

This mosfet is up in smoke. I think it also destroyed that resistor (R555). I cleaned the pcb, the rest looks ok.
What do you think? Will it work again if i replace this two parts?
Thank you verry...Last edited by schmo; 01-25-2014, 10:31 AM.

Medion LCD - no sound - Bad cap?
Hi there,
A friend of mine got a problem with a medion lcd (type md 30178).
There is no sound. Sometimes, if the tv runs a few hours, the sound appears.
If i connect headfones to the tv, the sound works everytime.
I looked inside and found this cap (1500uF /25 V). It is located next to a TDA8933t (Class-D audio amplifier).

What do you mean, will the sound come back after the change of that cap?
