Sony KV29X5U No picture, red light flashes 4 times then out then 4 times etc. Is this worth fixing?


What is the exact model number of the Sony TV? Check if the same issue occurs when connected to a different source device like DVD player or when the TV is not connected to the cable box. Disconnect the connected devices and turn ON the TV to check if the red light still flashes

I have a Plasma TV with black screen and 6 red light flashes.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

We had a power outage during a lightning storm this past weekend. We turned on the TV the next morning and it stayed on for 20 seconds then turned off. We rebooted it and same results. Thers is no audio...


Try power cycling the TV. First, unplug ALL cables from the TV, This may sound silly but there can be minute amounts of power coming from your other devices like the cable box or BluRay player and that small bit of power is sometimes enough to hold an electronic device in a particular state. Once they are unplugged, unplug your TV from the power source. Leave it out for a full 60-90 seconds.Reconnect your devices first, then reconnect the TV to its power source. If this does not work, there may have been damage done by way of a power surge.

No picture


(i) Disconnect all the cables from the TV including the power cable then reconnect them after a few minutes.
(ii) Make sure that the power cord from the TV is directly connected to a functional wall outlet.

If the standby light keeps flashing then service will be required.

My 6 month old tv went out during a movie we were watching and when i turn it back on all i get is a blank black screen. what do i do? It is a 42" Element


Hi Chris!

Please disconnect all the cables from the TV then reconnect them back after two minutes. Make sure that the power cable from the TV is directly connected to a functional wall outlet. Next, turn ON the TV and reset it to the original factory settings. You may also try connecting a different video source such as cable box, DVD player, Blu-Ray player, Playstation, etc to the TV to check whether the issue persists with all the video sources.

If the issue persists with all the video sources then service may be required.

No sound from any source from speakers


check your connections again and ensure you have the audio going out. With many tv's you need to change a setting in the menu, double check that as well.

No sound.


If you have a cable box reset it by unplugging it from power for about 5 seconds. Hope that works.

Hmm. let me see if I get U correctly. you use u'r theater system with a TV and the audio is fed via optical or U have DVD player that you can feed the audio via optical or coax. I think it is the later, if it is U could be having trouble with sound decoding setting of the DVD player itself. It's like mpeg out or PCM out instead of full DTS or 5.1 dolby digital decoding. If this is the case just use u'r dvd remote and check the audio play back settings. If this does not solve u'r problem, pls state u'r set up briefly, so tht I can understand the type of connection u use. Happy troubleshooting Rifaa
