Sharp LC-40LE820UN not coming on
This is a TV I had for a while. I have narrowed the fault down to the motherboard and I want to reprogram the EEPROM. Thing is I can't find any info on the EEPROM which is ic2004. I uploaded pics and a service manual.... -

Hi guys
I tested the backlights and they are lighting up at about 80v. I am getting a signal at the backlight on. I need a schematic if anyone has one or help identifying the swiching ic for the backlight power. Many thanks.... -

Sony kdl-42es441 Dead no standby light
Hi
This tv is dead but i am getting the 3.3v stand by and 3v for the power on on the power supply.I currently suspect IC6501 on the power supply but there are no markings on it. The power supply is a APS-334 and I would like to know that ic part number. Thanks.... -

Samsung UN60J6200AF backlight flashing
Hi guys
This TV backlight flashes constantly from the time it is plugged in. Unplugging the Mother board causes no change. I thought it was bad leds so I opened the panel and attached an LED tester and all the leds lit up which led me to conclude it was a bad power supply. I replaced it but the problem still remains.What I have noticed is the standby and the voltage across the mains filter caps are fluctuating and very low, eg standby 4 - 6 V and mains 150 - 160V . With the back light disconnected standby is 13V on and mains 390V. What am I missing here? I did a video when I was testing... -
Re: Sharp LC-40D68UT dead
Borrowed a usb microscope. Hope this helps.I just want to know if this IC n1337 can work in this configuration, pins 1 to 4 shorted to ground....Leave a comment:

Re: Sharp LC-40D68UT dead
Here are a couple photos and a datasheet of the 5V regulator. The power supply is a LC0919-4001ac. I'm just trying to verify if the regulator is the original one that should be there. As you can see pins 1 to 4 are all shorted to ground. I could be wrong but I don't expect this particular IC to work here, you can see it was installed by someone....Leave a comment:

Sharp LC-40D68UT dead
This TV has no 5V. It went to another shop before it came to me.I can see where someone may have changed the 5V regulator. I checked the datasheet but the configuration doesn't make sense to me. Can anyone tell me the part number for IC721? -

LG 50PS60 sound no raster
Hi All
This tv was initially dead with a shorted 5V line on the mainboard. The mainboard was replaced and now I'm getting sound but no raster on the screen. It doesn't appear to be priming the screen. I'm getting all my voltages to the Y-SUS and Z-SUS and all my fuses are okay. -
