Question about Panasonic TX-28DK2 TV

Tv is on stand by but won't 'fire up'

Have a Panasonic tx-28dk2. Whilst watching it flicked off into stand by mode. Used the remote and it came back on 2 days later it did the same but would not come back on, the screen flicked as if to come on but immediatly turned back into 'stand by'. I systematically pulled out leads and came to unplug one of the 'push-in' speaker connectors (the 'sub woofer') and after I could turn it back on. It seemed fine. I reconnected the speaker lead thinking it may have been a coincidence as I had turned the power completely off during the taking-out-of-leads. All was back to normal. It happened again, going to stand by, so I went straight to the subwoofer lead, started up after taking the lead out. So I left the lead out. Wouldn't turn on again the next morning but the speaker lead was unplugged. Have unplugged everything and turned it on and off no joy, picture flashes as if to turn on for a fraction of a second then goes straight to standby and blank. I'm guessing its a power surge/short somewhere and the circuits are 'protecting' themselves. Any pointers for a quick fix? Or is it for the knackers yard? I DO want a new flatscreen but, I do like the picture and sound of this telly, and I could do with saving the pennies.

Re: Tv is on stand by but won't 'fire up'

I don't know the age of your set but I've found some Panasonics with a loose connection on the heat sink (an aluminum plate standing vertically on the circuit board) of the regulator IC (chip). The IC gets its ground through the heatsink. If the ground is open the power supply puts out too much voltage and causes the set to go into shut down. I've found this problem several times.

Re: Tv is on stand by but won't 'fire up'

Had the same on my Panasonic wide screen, took it into the shop and was told the tube was dead, so too expensive to repair so had to go. Went on ebay and got a £30 replacment set until i can pick the flat screen unit i want.

Freeeview update has not allowed BBC1, BBC2 Channel 7 and 8 to be viwed. They have been deleted from the menu on digital. I can get BBC1 and BBC2 on analog.

Make sure all cables are securely connected to your Freeview Box or Freeview TV before you begin

Do a Factory Reset of your Freeview TV and then do a rescan of new channels. If successfull then all channels should be back and working.
