On my 26", I now get vertical and horizontal colored bars/lines until I turn the set on and off numerous times (waiting for the delayed click after turning off).
How long have you had the set for, and when did the problem occur?
Additionally, what is connected to the TV for devices (DVD, cable box, etc.), and do you have the same issue regardless of which INPUT you select?
If you bring up the TV's MENU, does the MENU come up over or behind the lines?
About 7 years. Problem started about 2 months ago and happens every time I turn the set on.
No cable box, just a DVD recorder abd Blue Ray player. Disconnecting them does
nothing.
Can you please carefully reply to the entire Info Request so that I can help you and save time?
Specifically.....
No. My TV menu is provided by my recorder via channel 8 here in Phoenix. Until
the TV gets a picture, I bet the colored vertical/horizontal bars (with sound though)
no matter what the input is.
No, you need to use the MENU button on the TV itself. The TV has it's own internal MENU that supercedes anything else connected to it. Do not use the cable box/recorder remote, press the button on the TV remote or the TV itself and let meknow if it comes up.
I have to turn the TV off for awhile and then turn it on again to have the picture problem. But, I doubt I'll be able to get the menu displayed. This will take awhile for the set to cool to room temperature, probably a couple of hours.
That is okay. I need to know the answer to this so I can accurately diagnose the problem. Otherwise I'd just be guessing. Please reply back when the set has this issue and we can continue from there.
I turned on the TV and had the usual problem. Hitting the menu button on the TV did nothing. I could see sometimes something faintly in the background, the same as if
it was on a channel when I turn on the TV.
There are basically two problems that would cause this, the Power Supply, or the LCD panel itself are failing. Voltages need to be measured at the power supply outputs, using a DMM with nothing connected to it but AC Input. If the readings are proper, then the other boards need to be connected one at a time, until one causes the voltage to shut down at the output. Price to replace the power supply is around $100 parts and labor. If the supply outputs power with all of the boards connected, then the LCD Panel has failed and will cost you more than a new TV (around $250) to have replaced and it is not cost effective to repair this set. I wish I had better news on this set, but the symptoms you're having indicate a failure in one of the components responsible for powering, and processing the LCD panel itself (including the LCD panel).I would think long and hard before deciding to put that kind of money into a 7 year old flat screen, as a new TV would cost you around the same as repairs. I wish I had better news for you.
