Of course, worked great for a period of time! Before it could run for any period of time and then will reboot itself. It did not want to shut itself off a few times, so I had to pull the power plug. Now lucky to get 1 minute of video then reboots.
Drops out too fast to get some voltage readings.
Have worked on many brands before but not familiar with this problem from LG. Thinking either the BG soldered main chip is in need of reseating or perhaps an Eprom failure. Main board failure or entirely wrong-LEDS??
Main chip doesn't get hot enough to shut it down.

Re: Onn Tv made for Walmart

I managed to clean it off. While it was a bit damp I was able to read the number. It is SN51DP. I will start testing voltages at each pin now that I know the pinout. I will check for pin to pin and pin to ground shorts. Thank you all VERY much.

Re: Onn Tv made for Walmart

I will try to clean it off. Thank you again. The LED backlights are completely removed and there was a short across an smd diode on the power supply board. I took it out and it tested fine. I traced both sides of the diode as best as possible and it appeared to go back to the LED driver IC.
I will reply back with my cleaning job.

Re: Onn Tv made for Walmart

Yes i will do that. Thank you.

I have a model ONC18TV001 made for Walmart. I was hoping maybe someone has a schematic or can help me with an IC part number. The LED driver IC has failed. I cannot read the marking on the IC. Looks like a 10 pin msop package. Thank you.

Re: Philips 58pfl4609/f7 TV not working

Hi, I am new here but have been a viewer for quite sometime. Thanks for having this multitopic forum. I also have the Phillips 58PFL4609 flat screen.
It does have a power supply issue. Here is what I can inform you, and I am hoping someone knows where I can find a schematic. Manualsunlimited does not have this one. Anyway, ShopJimmy does carry the repair kit for this for COMMON problems only. I have also read that the kit does not resolve all the issues with regard to no-start and maybe no standby. On the underneath of my board I have...
