TV signal lost

have you checked the antenna qnd antenna cable are ok.

My guess would be that your PS3 has somehow switched the output settings. You can reset the settings by pressing and holding down the power button till it starts blinking. Try connecting it with your RCA cables to a TV and if that works try going into your settings and setting the PS3 back to HDMI.

Hi,
please call a specialist in that for assistance.
As of now and future: Follow what everyone says: "Turn off the modem and TV during a lightning storm".

try first if you have not to remove set and any cable or sat box from power, a box etc can cause this--when you plug back the units will try to reboot, cannot hurt and may help.

Sony Video Cable

Hi there,

This problem could be caused by faulty cables. If you are using an HDMI cable, you will need to replace and see if this solves the problem. If you are using RCA cables, you should check that the cables are all in the correct inputs on the TV and outputs of the device that you are trying to view from. The Yellow cable is the one that carries the video signal. If they are all correctly seated in the devices, try and disconnect one of the other cables (Red or White), and put this cable into the Yellow input of the TV and the Yellow output of the viewing device (this will determine if the cable is faulty). If this solves your problem, then the Yellow RCA Cable is faulty and you will need to replace it.

If these solutions still do not resolve your problem, this could be caused by a faulty RCA input on the TV or a faulty RCA output or faulty HDMI in and outputs. In this case, you will need to take your TV or Viewing Device back to it's supplier if it is still under warranty, otherwise you will need to take it to a repairman to repair these in and outputs. You cannot do this kind of repair yourself as these in and outputs are mounted directly onto the circuit board of the devices and specialized equipment and tools are required.

Thank you for using FixYa! Have a great day and please remember to rate this solution.

Unplug the tv and the cable box about an hour,replug both devices back in.The cable box will reboot itself and upgrade it softwares.The tv should have signal again and work.

Electrical Storm normally damage Tuner in TV.
Symptoms in tv like poor analog tv signal reception shows replace TV Tuner.

Looks like someone sold you a unit only partially working.

You may need to have the main board replaced, which is likely why the previous owner sold it.

My solution would be: Buy an inexpensive surround system and a VCR, Use the VCR as your tuner, and plug the audio output from the VCR into your surround system.

This way you will have a tuner (the VCR), and sound through the surround amplifier. You can also plug the audio output from your DVD player direct into the surround amplifier. This solution would likely run you less than half the cost of replacing the main board in the TV.

hi everyone, well i,ve solved our problem. i had the same head bashing problem for months,tried everything.what you have to do is turn all display settings to 0 and then run tv for several hours like that,then slowly bring up brightness and colour only leave contrast at 0. i,ve tested this for a week now and bingo the light show is over at last,my god the relief.good luck everyone
