Sounds like fluorescent tube has gone, but you say this is LED? Newer tvs are LED. What you have, may be LCD, in which fluorescent tubes were used. You have no recourse.

SOURCE: tv not work

Well, don't feel alone.
Everyone is having the same problems with many brands of TVs.
Somehow built to fail after warranty. I'm sure it's a power supply related problem. From this link here, there is a Service Manual for the 42PF7320.
http://www.scribd.com/doc/6528782/Philips-42pf7320
Page 27 says error code 7 means 8V6 supply.
I'm thinking it's the power supply for the screen. I can't 100% certain.

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

there could be a number of things effecting it.
check that your TV is not set to only go to the sound bar. This is like plugging headphones in your phone......the tv is probably still seeing the sound bar and the only way you want to hear sound.

try plugging headphone into it and see if they work through that

Samsung led tv no picture


What did you do when you say you cleaned the screen? If you shine a flashlight on the screen can you see some very dim picture? If the back light is out. This will require replacing the power board.

I awoke this morning to find the sound on my Apex Digital LD4088 LCD tv is dead. The picture is fine, but sound is dead, how do I solve this?


Download the user manual to your TV. Clik here to download it. See whether audio options to it are set right. If all are right, check its speaker. If speaker is OK, the audio output circuit section should be troubleshooted.
If you feel any difficulty in downloading the manual, send your email address to me. I'll send a copy of it to you by return mail.

Picture is gone! :*(


the picture tube (what makes the TV picture work) has blown out. Just call you nearest tv reapair shop and purchase a new one. (these are kind of expensive!)

(Also, if it's fifteen years old, i think it's time to get a new T.V. hint. hint.)
