Turning on TV after power outage

I have an older Philips TV and after unplugging this TV or having a power outage, it takes for ever for it to turn on again. There is a red light that flickers on the front with an St. I have no manuel for this TV as I bought it second hand. Any answers?

Not sure what you mean by "older", but I assume it's a CRT display. It takes some time for a picture tube to come up from a completely cold start. It has to get all of those electrons hot enough to start flying around, and also build up a high voltage on the screen. You don't notice it in normal operation because the power button doesn't really turn everything off, but just puts the set in standby mode. Unplugging, though, lets everything cool off completely.

If you're talking real antiques, with tube-type amplifiers, then the warmup time could be even longer. I remember as a kid watching the blank screen for a couple of minutes before a picture appeared.

What you describe sounds like normal behavior for a CRT television. Not sure what's up with that flickering red light, though.

My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...


You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

It takes 5 to 7 minutes to turn on my Magnavox HD TV


IFyou feel confident and can locate switch mode power supply with back removed.
Try warming switchmode power supply before turning TV on.
If TV turns on normaly then there are some small capcitors that are a common cause of this fault.
Otherwise look for DRY or CRACKED solder jointson PCB
BUT DON'T do any of the above if your are not confident send it to a TV repaiman.

Power Outage


The power supply, or one of the scan amplifiers has some damage. The set will require shop service.

More than likely the set was going to fail anyways... Turning off the power source to a TV should not do any kind of damage.

If the screen won't come on then the diagnostic will never show. The 4 blinks is an error code. If the set is older than 12 years then it doesn't owe you anything, you got your money's worth out of it. Average life of any tv from that genre is 8-12 years. It's time for a new set, or take it in for an expensive repair ( pending parts availability).

Tv wont turn on


Hello tvlover, The outage actually is not the problem but the spike that happened when your power came back on did the damage. That aside, you may just have a blown fuse. If you are able to and feel comfortable work with electronics, with the TV unplugged from the wall, take the back off of your TV and take a look at the line cord going into the circuit board, this will lead you to a fuse holder, look at the fuse and see if the filament inside has been blown (opened). If the fuse is blown relace it with one of the same amperage and voltage which should be written on the metal part of the fuse. Once the fuse is replaced, plug the power cord back into the wall and power it up. If it comes on and plays, that was your problem and you can turn the TV off unplug it and put the back cover back on, plug your TV back into the wall and enjoy. However if the fuse blows again, that could indicate a problem with a short somewhere in the powersupply path and that will require troubleshooting the set. Now I we have to troubleshhot this TV you will need a multimeter, an oscilloscope, and a schematic of the TV (at a minimum). If you do have electronics experience to this level and do not have this type of equipment, You will have to take the TV to a repair shop. Thank you, and I hope that it is just a blown fuse.

Power outage caused child lock, 2729 model tv


I'm guessing what you have there is an Akai CFT2791 made by Samsung? And a CFT2729 is not a good model number. You will need to get into the menu and then sub menus to change or turn off the child lock feature. The procedure is well described in the owner's manual and I have the manual. You can email me privately I'll send it to you... premtech@willapabay.org Bill
