Re: ATVIO with a bad power supply. Help, please!

Already took the thing apart and back together again.

The panel has 3 strings of leds, all of them light up both individually with 3V and as a string with 24V. I measured the voltage on the board when it's on (at the leds connector) and it gives me very low voltages (something like 3 or 5V).

I'm not that tech saavy when it comes to electronics, I mainly exchange broken parts (displays, digitizers, etc.), and the shop's main activity is computers, laptops, smartphones and the ocasional TV.

Thanks...

Hello! I have in my shop an ATVIO 32" chinese piece of crap with a bad power supply. Motherboard and power supply are in the same board.

The TV turns on, blue led indicating all OK, but no lights. Quick flash when powering up and then nothing. I've got picture. Already tested all the leds and they are OK. Fuses are not blown. So the problem must be in the power supply section of the board, right?

Found no schematics, no manuals, no parts, nothing on line! This TV is assembled in Mexico (VIVA MEXICO!!) but all the parts are chinese. I hope the pictures are clear...

Re: LG 47LV5500 - No picture, no back light, no sound, powers on.

The heat solution actually works!! Thanks a thousand!! I reflowed the main board's main IC (the one underneath the heat sink) with a heat gun and flux paste, and it solved the issue beautifully!
