No picture My mom was watching TV last night, when the tv made a popping sound and shut off. When she tried to turn it back on, there was no picture, the Timer/Standby light keeps flashing, and there is sound. As of the time of this posting, we do not know what to do. Thanks in advance to anyone who can provide some help.

Backlight issue?

There could be a few things that would cause this. I would suspect that you have a problem with either the power supply board or the main board. Based on my experience, the main boards go before the power supplies. What is the model #

REPLACE THE LAMP IT IS LOCATED IN THE BACK OF THE TV THERE ARE INSTRUCTIONS IN THE OWNERS MANUAL FOR REPLACEMENT IT IS CONSIDERED CUSTOMER REPLACEABLE ITEM.
PART NUMBER 915B403001 Lamp (180W)

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

the light source is out. the new lamp will cost around 250 easy fix.

I would suggest to read what other members have reported by clicking here.
Good Luck.

For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
Thanks,

Open the back cover and check any fuse blow in Y Sustain board or Z Sustain board. If you do find the fuse gone, replace the board. Good luck!

Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations: What was the TV doing (it actions)prior to it going out? Did you hear any sounds before it went out like buzzing or crackling? What do you hear when you try to turn it on now, clicking? These questions are just to develop some background into what might be happening to your set. Thank you, Shuttle83
