SOURCE: Panasonic Plasma no sound, can't change channel

Yes the control board would definitely be the offender here. But a word of caution. Oftenj when this board goes 2 other boards are also compromised and not always obvious at the time people think they can just swap the board out.
It went for a reason, not just old age. So it is better and cheaper in the long run to get a professional to check it out.

Also from a safety aspect, this is the High Tension area of the TV. Also be aware that radiation of the X type is in abundance at the rear of the tube. The TV must be grounded when opening ( but my advice is dont!) Let the professional do it

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Tv powers up but goes directly into stand by mode


An Electronic component has failed. Unless you can repair circuits, take it to a shop or friend who can. Consider cost of replacement. A few hundred will fix an old tv, a couple more and you have a whole new unit.
