Samsung TV BN64-01396A does not respond to cable box blue light is on TV no picture but flashing at bottom of TV

After purchasing it a year ago, I have had all sorts of problems with a Coby 23" LEDTV2326 since buying it new in the box at a very reputable long time established, high end pawn shop. It is hooked up to HDMI to my cable box and was working fine for the first 9 months and then it started showing the blue light coming on, but no picture. It is turned on and off through my cable box remote control. Every day it takes longer and I'm not even sure each time what it takes to get it to come on, but I just read something about sharing the power with another device (the cable box) in the same outlet. So, I unplugged both tv and cable box, then just plugged in tv without the cable box plugged into the outlet. I pushed only the tv button on with the remote, the blue light came on and the tv came on all the way on. I then plugged in the cable box and it eventually came on with the HDMI signal and the tv was again working as usual. I suspect somehow this relationship between the cable box and the tv is the problem, but I'm not sure. It also seems that this HDMI source is a problem even though the tv is designed for it. The TV picture is perfectly fine, so I have a hard time believing the failure of the tv to come on is tied to a flawed part in a 1-2 year-old tv, particularly when the picture looks perfectly fine with no defects and the blue Led light on the tv come on. I think it has something to do with the HDMI line to the cable box not transmitting an effective picture to the tv reception. Cox Communications Cable is one of the worst of the worst companies for giving customers old, outdated and defective cable boxes, cable lines and their customer service is horrible and unhelpful. So customers think it is their tv, when it is really the cable box. That's why the blue light to the tv comes on, but no picture - maybe. I found out that the last cable box they gave me was no longer even manufactured and hadn't been manufactured in two years prior to the one they gave me, it was refurbished, yet they were going to stick me with the same model when the other one broke down with whining and clicking noises and it was a DVR recording cable box and I didn't even order their monthly DVR service. They stuck me with it because they wanted to lure me later into ordering the DVR program recording service. That box was a nightmare. Every night, Cox would load their entire tv programming for the next 24 hours into the box so they could record my viewing habits without my permission and then drop in commercials based on my viewing habits in the middle of other commercials that would suddenly disappear when they clicked over to the inserted commercials based upon my perceived viewing habits. They hook up my computer and my phone all onto one system with the tv and it gets to be very "big brotherish" like all the other data collection scandals that are violating our privacy rights.

Now--first--connect the DVR cable box HDMI output to the HDTV HDMI input (use the lowest numbered one e.g. HDMI 1) for this connection. Use a standard (not Monster brand) HDMI cable for this connection. Then turn on the TV, turn on the cable box and switch the TV to the HDMI input. A picture should come on. You may even hear the audio on the TV speakers. If so, that is OK.

Then--connect the component video output of the DVD HT to the TV component 1 input. Use a three wire component video cable with red, blue and green connectors on each end. Connect color to color on both ends. Then turn on the DVD, put a DVD in the player and start it running. Switch the TV to the component input and it should show a pix. The audio will come from the DVD player speakers.

If your DVD player does have an HDMI output, you can use it and just connect as above to the second TV HDMI input.

To get audio from the cable box out of the DVD player speakers, you will need to connect an audio cable from the cable box go the HT amplifier. Use a set of RCA patch cables and go from the analog audio output of the cable box to the rear panel audio inputs of the DVD player. The owners manual for this unit will give directions on using this input. Since your HT unit does not have any other inputs, you will not be able to get Dolby Digital audio.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

Good luck. Remember, the owners manuals all have hook up connections diagrams. Sometimes they will help.

Dont forget to rate me as fixya..

Hi, maybe the TV controller board is blocked, you can reset it, by disconnecting power cable from outlet for about 5 minutes, if that doesn't work, possibly and internal board or component must be repaired of replaced, in such case it's better to contact an authorized Samsung service center or technician to check your TV.

Hay Junior!
You have a power supply problem and unfortunately this repair sould be done by one who knows electronics specially tv electronics..

When you run the cable box and the blue ray player to your receiver you use two sets or cords yes? there for you need to run two sets of cords to your TV from the receiver. Have you done this? Both the DVD and Cable box will have different inputs to the TV. Turn the cable box on and cycle through the inputs on the TV. One should pop up for the DVD and a different one for the cable. Let me know if this works.

Dude, better check your cable and also your TV's power management settings. This might also happen due a issue with the HDMI output of the satellite box.

Purchased a x810 & everything tests out fine except TV signal sounds from cable box. We have the Comcast cable box connected to the 50" Samsung Plasma TV hooked up to Samsung x810 Soundbar all using HDMI cables. But we are not getting cable shows sound through Soundbar. Please advise

return to seller or take authorized servicer.

Those Samsungs and most other HD units can fail within 6-18 months of purchase.. I would contact Samsung and go up the corporate ladder for help. Otherwise you may be looking at a repair bill that is as high as the cost of new unit.
