    I have a Vizio TV that went out during a storm. TV has no backlight, or picture (not sure about sound but I don't hear anything). Fuse is good and the 24v is good coming from the power board. I'm not sure about the standby but assuming it's good am I looking at a main board replacement?

    Hi Tampatec, I got a SONY KDL42W800B which has back light but no pictures. Upon turning it on, it powers on and make and produce the sound for about 3 seconds and then stop but still on black screen. First indication from approved sony repair shop indicated cracked screen. There is however no physical evidence nonesoever. The cost of fixing was just too high and am not sure if i trust their diagnosis. I tried to open it but after removing all screws the first half cover won't come out even though it can lift from the bottom. Any help

    My sony 4k tv remote doesn't work and on the bottom i'm getting a blue/white flashing light with a x81 demo video. That being said i can use my 4k player remote and only use tv input or volume and on and off. I'm getting picture the tv remote has new batteries but same thing. Should i get a new remote for the tv or what?

    Hi there! Thanks for this video, but I have a quick question. My XBR-49X830C recently stopped working after two years of use. I spoke with an authorized Sony repair facility and they said the bad part was the A2072555C logic board. I ordered a replacement and will attempt to fix it using your videos as guidance, but I was wondering if you had any pointers on when to attempt re-installation of the Android TV OS. Any tips or pointers would be great. I already have the OS saved to a USB drive and my replacement board should be arrive today.

    I have a Sony KDL-52XBR6 – Same problem, no lights, no power, power button does nothing. The main board is out of stock. Should I try the power board or measure the voltage?
