Chosen Solution
Hi I noticed the standby light was blinking and didn’t think anything of it. I pressed the power button and it stopped. Then I noticed it again. Not thinking much of it, I unplugged the tv and plugged it back in after about ten minutes. Unfortunately, I didn’t know at the time that you can count the blinks for an error code. Sort of a moot point since I cannot proceeded a number of blinks other than the fact that at least there were blinks prior. All I can say is that if I hold the power button in for say three to five seconds I hear a click but that’s it. No power light or even the slightest flicker, just the sound. And idea on what board I can check? I’m confident that I can replace a board, but want to be sure I buy the correct one. Thank you! Here’s a picture of the P board, A board, A1 connector showing only 7 pins, and the flow chart I was following. I’m confused by this because the flow chart says to momentarily ground pin 8.
After buying a new power board, the TV didn’t work and all voltage readings were the same, so I ruled out my power board and put it back in. The issue was with the A board….the main board (TNPH0914) suffix AC in my case. After replacing that board it works fine! I kept the old A board, so if I figure out what exactly went wrong, I’ll come back and post the fix if it’s possible.
@djodts start by checking things out as directed on the flowchart. To check the fuses you will need a multimeter and check fuses for continuity
Fuses are outlined on this one
It might also help if you take some good pictures of your boards and post those with your question. That way we can see what you see. Use this guide for that
Hi @djodts Here is a link to the service manual for a Panasonic TC50OS30 / GPF14DU Chassis TV. http://elektrotanya.com/panasonic_tc-p50… To download the file wait until the sentence below the Document preview box chages from This file is downloadable free of charge: …processing… to This file is downloadable free of charge: Get Manual and then click on the Get Manual. This is the download link. Be patient it takes a few minutes to find the file. Here is an image from the manual showing the A1 connector on the A board in circuit. It shows what you have i.e. 7 pins. Therefore, are you sure that you have got the correct flowchart for your TV? Click on the image to enlarge it for better viewing.
