RCA LED 42A55R120Q no picture
Hello all and thank you for allowing me to join your great group.. I have a RCA LED 42" model: LED42A55R120Q its power up fine and can not change input source or change channels, it shows in the screen a small window at the bottom of the screen like someone is pressing the remote button to lower the volume, so it shows the number "0" for lowest level of volume, and stays there like someone have the lower volume pushed all the time. I have remove the batteries from the remote and still the same, also pushed many time the buttons behind the TV, and unpluged the power still the same. Any insight on this would be greatly appreciated ....

Re: RCA LED 42A55R120Q no picture
So the TV functions fine, but the volume is constantly stuck at zero?
You have taken a good step by cleaning the buttons as this is a #1 cause. However, sometimes the buttons get stuck inside.
When you open up your TV, remove the button board and see if the problem cures itself. Then, to cure the problem permanently (while still having buttons), use a bit of contact cleaner on the buttons. I had a similar problem with a TV that would turn off as soon as you turned it on.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: RCA LED 42A55R120Q no picture
If you unplug the button bar can you change the volume using the remote or is the remote sensor in the button bar?.
You can check if the remote is sending signals by aiming it at a digital camera
and viewing it on the camera screen.Please upload pictures using attachment function when ask for help on the repair

Re: RCA LED 42A55R120Q no picture
This is what I have tried, removed the batteries of remote control, and unplug the button bar at the same time, and still the same, then I tried with the cable box remote and still the same, then remove batteries of both remotes and still the same.
Tom, I have no access to the setup menusComment

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... -
On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.
It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related.... -
Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
Hi all,
This is a repost since I never completed this fix. I just left it, but now the receiver powers off into safe mode and does not complete the Self-Diagnostic when i start with those buttons pushed. It says it is, but does not do the diagnostics and does not show any faults or that it has none, which it should do. So here i am again. The previous post did have a schematic but I think it was cut off somewhere. I do not know what board it is referring to. Any help would be appreciated.
I have searched through the forums and have not found anything about my problem. So,...08-30-2023, 08:35 AM
