          Hisense stuck in Colors cycle like test pattern.
          by nono34
          Hello,

          I accidentally changed the project ID in the service menu of my Vidaa Hisense 100U7KQ TV. When I turn on the TV, the screen displays an RGB color cycle (test mode???). I contacted Hisense, and they sent me a usb_MTK_9618.EU.bin file, but it doesn't work. I can see that the USB drive is being read, and it flashes for about 10 minutes (the screen remains in the color cycle during the firmware reading), then the TV turns off and restarts, but still in the color cycle mode.

          I want to mention that the 4GB USB is formatted in FAT32 MBR. I've also renamed the file to...

          Sony Bravia XBR-65x900e Test pattern
          by m3tal82
          Hello all,
          I got this beauty of a 65" Android Smart TV from a roommate whose boss through it out because it didn't work. I've fixed a few TVs before, but was being stupid on this one:

          Original issue:
          TV powered down after a minute or so, but picture was fine.
          Tried replacing main board, which didn't work. I should have just replaced the AC Power board.

          Months later, I replaced the power board, so I can see the screen. I lost / threw out my original main board, and there is now what I believe to be a defective main board in the TV. My symptoms...

          LG Plasma TV Model 50PN4500-TA
          by angelos
          Hi Guys, I desperately need your advice on this set.
          When pressing standby to "ON" then the Panel has a pre charge flash and further no image. The audio works 100%. I have the TV plugged into HDMI input.
          I measured all the main board voltages and they are all correct according to service manual. I then went to the logic board and put a wire on the "Auto" to generate
          its own test patterns. This works, telling me that the plasma panels are ok. After removing the jumper we go to having a black image.
          I cleaned the ribbon from the main to the logic board,...

          How Can I test PWM DM0365R?
          by chth96
          Hello
          I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
          So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
          I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
          I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

          LG 60PV450 Possible Bad YSUS Need help confirming Diagnosis
          by PlasMatt
          I have an LG plasma that after reading through a bunch of posts and doing some testing I believe has a bad YSUS board. The problem is that that doesn't make sense to me for some of the symptoms. The problem started yesterday. While watching a movie the TV just shut down like I pressed power. I have it hooked to a PC and use RS232 to turn it off and on so I thought maybe something had glitched there. I turned it back on and finished the movie with no problems. The same thing happened today so I checked logs to see if something in the control glitched and sent an off command but it didn't, After...
