Re: Display Issue with Sharp LC-60LE660U
Left side Bobbit should fix it.
It can be done on its stand in about 15 minutes.

Re: Samsung PN59d6500 power cycling issues
Issue is mostlikely on the IC firmware found on the main.

Re: Vizio E70U-D3 - No Backlight
Replaced D103 SF50JG (600V 5A) with MUR460 (600 V 4 A rectifier). This fixed the problem. Thank you!Leave a comment:

Re: Vizio E70U-D3 - No Backlight
So the problem is located on the Power Supply most likely for lack of PFC voltage?Leave a comment:

Re: Vizio E70U-D3 - No Backlight
Hmm. Getting 0 Volts DC on each side of TCON fuse (F100). *edit* Nevermind, my red probe wasn't placed well. Am getting 12 V both sides.Last edited by hardbox; 12-16-2019, 01:59 PM.Leave a comment:

Vizio E70U-D3 - No Backlight
Vizio E70U-D3 - No Backlight
Customer brought in for has sound, no picture or backlights. Replaced the backlights with set from SJ and the backlights still doesn't turn on. Made sure everything was connected and they are working. Pins 1-5 at CN201 on PS which are the LED_OUTPUTS are reading 0 volts, however am getting the 16 V to main and can see image with flashlight. Also not getting any voltage from main to LED's at CN403. What could cause this?

Epson 5020UB Projector - Temp and Lamp Light Flashing
Need some idea of where to start to fix this projector. According to the user manual, when the temp and lamp lights are flashing there is an internal problem which doesn't give me much to work with. Need some input. The fans run for like two seconds when attempting to turn on then goes straight to the error code. Since it's not a lamp, fan or temp error, I'm leaning towards the power supply.

Vizio D40-D1 - No Sound Only
Had a spare mainboard and speakers from another set, once that didn't work I ordered a repair kit from SJ to try and fix this TV. I made sure to check that the TV speakers are set to On in the menu. Either I have defective parts or bad speakers which is unlikely. So far I tried 3 mainboards and two speaker sets, can it be something related to the panel board? Testing sound using the HDMI and the built in Youtube app. I don't come across many sound issues, but I expected to be only the mainboard. Am I not looking at the right areas?Last edited by hardbox; 06-10-2019, 02:55 PM. -

Re: How to Fix your Vizio M470NV and M550NV
Hello Nick, I have a Vizio XVT3D424SV that shows no picture at all. The LEDs will come on. Done the diagnose by disconnecting one of the two ribbons between the T-con board and the panel. Still not picture. Do you think it is the mainboard and will a reflow help?
ThanksLeave a comment:

Re: Hitachi LE42H508 no power....
The LEDs are bad. That will take the PS down. If you unplug the main. The 12v will stay. Is not the Main, is the LEDs. Trust me.Leave a comment:
