No power We had out tv on yesterday and it just turned off, like someone hit the power button and it won't turn back on. We have tried leaving it unplugged for a while and plugging it in to other outlets but no luck.

You could have a bad high voltage transformer or problem with the power supply. If the set is over 6 years old, It would probably be better to replace it.

TV won't turn on power light flashes 10 times

Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

I need help I just won a tv but it didnt come with a remote but I have a RCA remote transmitter. Im trying to program it for the tv but I dont have the book anymore can you please help me The tv is on but...

This Web page should allow you to find the codes for any devices you want to add for this remote.http://remotefinder.rca.com/default.aspx?site=rca
Other than that there is an easy way to program this remote.
1. Turn on the device by hand. 2. Hold down the device name key.(hold the TV button to program a TV) 3. While holding down this key also hold down the power key until the red light turns off and comes back on. Then release both buttons. 4. From here hit the power button repeatedly until the device turns off. 5. Hit the stop key at the bottom. Now the remote is programmed for that device.

I hooked the ps3 to the philips tv. turned on the ps3, AV1 displays in the corner. Nothing else happens, I am expecting the ps3 logo

give this a try...

Leave the TV running, go over to your PS3 and turn it off.

Once its off, hold the power button down till you hear a beep, KEEP HOLDING THE POWER BUTTON till you hear a double beep. The PS3 will shut itself off.

Give the device a couple of seconds, then hit the power button one last time (just turn it on, you don't have to hold it).

If all went right, your baby is back up and running...

50" philips won't power on. get the 4x red blink led light

i have fixed 3 of this tv, with that exact problem in the last 2 weeks, needs a power supply, you can try to unplug it again, plug it in, hit the power button, as soon as it turns green, unplug it again, after 15 seconds , plug it back in, if power doesnt turn on by itself, turn it on, if it turns red again, emediatily hit power again, may have to hit power a few times in a row, but most of the time you can get it to come on this way, once it is on, it should run ok, until you turn it back off, but not a fix, needs power board

Sony FD Trinitron WEGA KV-24FS100 24" TV On/Off problems

I have spent about 4 hours tonight researching several tech sites and the Sony service manual for the same problem with my Sony KV-32HS510 unit. I was able to download the manual from a website http://www.eserviceinfo.com/downloadsm/31649/Sony_KV-32HS510.html and a TV Repair training lecture paper at http://www.repairfaq.org/sam/tvfaq.htm#tvhvp .

These TV sets have a safety feature where it will shut back down if a high voltage is indicated. Unfortunately, the electronics for these safety features are not very reliable and give false indication. Letting the unit sit off lets the capacitors leak voltage as well as cool off. These two factor help with the unit not falsely indicating a high voltage condition.

The D Board seems to be the most common failure component, but a 6 times flash could be an overcurrent/voltage failure from the A, B, or M boards. A 7 times flash is a Horizontal Deflection Stopped error with no additional information given in the manual for a fix. Again, in most blogs, the D Board seemed to the source of the failures.

A refurbished D Board part no. A1300319A can be bought for around $200 with a new board at $550 per the www.partstore.com site. Then add $100-$200 for an actual TV service technician and you have a repair bill approaching the costs for a new flatscreen TV.

Some tech types posted that they have actually repaired their boards by replacing individual components for around $40. You may find a service shop that can do the same component level repair at the $100-$150 level cost. It turns out that the closest authorized Sony repair shop is 2-1/2 hours away from us. Good luck finding someone close by.

We were able to get our TV to come back on after dozens of attempts and plan to leave it on until it dies all together. I may attempt my own D Board replacement when the time comes.

Good luck!
