Here is a manual. Pay attention to page 5 for the power failure circuit that is on the main board. Pages 29 and 30 also have good info. Pages 42 and 42 have flow charts. they have complete parts listing for boards too.Comment

Re: Sanyo dp50747 Chassis 03 Audio no picture
Is there a panel reset sequence? How can I select it if so? Panel still not coming on but I have audio. I also do not have a remote for the set so I do not know what input is selected if one.Comment

Re: Sanyo dp50747 Chassis 03 Audio no picture
Exactly, what I saw and i replaced those components. I still am not getting a picture on the panel. I don't have a remote so how to bring up a menu when I can see anything would be the next thing. I plug the set up turn it on and then I hear the static sound. I plugged the hdmi cable in but can't go to menu to select hdmi port since I can't see it.Comment

The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.
The player processes the audio signal using two different reference frequencies. The "R"... -
Hi members, I came across this forum when searching a fault on my LG 55UB850V TV.
Rather than hi-jack another members post/thread I thought I should start my own even though it's an almost identical issue.
The thread I refer to can be found here:

Hello,
My Plasma Philips 37inch chassis FTL2.1 does not show picture. It automatically goes into protection mode after 30 seconds (red led blinks at 3Hz)
Is there someone having any symptom like this? How to fix it?
Thanks in advance!08-06-2024, 09:55 PM -
Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
