My electricity popped on main switchboard & TV went off, there’s no red light showing for standby. This isn’t the 1st time this has happened as TV has long spells of not being used. In the past your suggestions have worked perfectly but unfortunately not on this occasion! Have retried your advise ie unplugging / holding standby button on back of tv for 60 secs / Holding both volume & standby button on back of tv for 60 secs / Checked fuse etc to no avail. Was hoping to have a lazy Sunday in front of TV but don’t think that’s gonna happen!! HELP Thank you so much….
Hi @asap911 , Try using the controls on the TV. Press either the Power button or if that doesn’t work perhaps the Menu button. Here’s a link that shows the TV controls for your model TV
The key here is that there is no standby light at all. This is usually an indication of some type of catastrophic failure of the power supply. It might be as simple as a blown fuse given that you said that the power “popped”. Check that first. The fuse should be easily located. Change/check that first and update this with the results. If that does not resolve the problem, post a picture of the power board for starters and we’ll provide additional info and instructions. Dan
Hi @cacornett58 , What is the model number of the TV? The standby power light coming and going indicates a loose connection or a poor connection (dry solder joint?) that may be affected by temperature perhaps i.e. cold contracts- no connection, heat expands - good connection. It doesn’t take too much to make for a poor connection. The low voltage signal from the power board to the mainboard that power is available so the standby LED would be on, could be disrupted as the voltage (5 -11V DC) can’t as easily overcome the possibly higher resistance connection as would 120V AC. You may have to check if there is a service manual available online for your TV and hopefully that is has a schematic of the power board so that you can initially trace back the standby power circuit. Just search for Panasonic (insert full model number) service manual to hopefully find results
