Hi, my television's picture goes in and out.. and when it does, the stand by light (red) flashes on and off. I am still able to hear sound, but there is no picture every thirty seconds or so for about 30 seconds, if not longer. Is this something I can fix myself?

How many times do this standby light flashes at one time switch ON? Count it. These flashes are fault indications. From the number of flashes, you can get an idea about which section circuit inside it is faulty. After confirming it, If you wish to get more details of these blinking codes, check this link.
Did you get your set fixed or did you replace it? My same set did the same thing. Turned it off for 2-3hrs after watching it and when I tried to power it up- nothing but the sound it would normally make just before the major power up, sort of a relay click sound. No picture or sound but the red light blinks non-stop.
upon hitting the power button, the red light showing on the front of the tv should flash a couple of times, the screen should come on and the light goes off..the red "stand by " light stays on and we cannot get the screen to come up..needless to say, cannot get to the menu to change any display options...any suggestions?
This could be a scan amplifier failure, and there is a loss of high voltage to the CRT. Part of the power supply may have also failed. In these sets, if the CRT emission goes low in emission, or the CRT goes defective, the bias supply to the CRT will go in to protect.
An experienced TV service tech can troubleshoot the set and give you an estimate for service. Considering the age of the set, the cost of service may not be worth it.
Hi i have been hereing a lot 0f these problems today here is my list of things that go bad when BLINKING RED LIGHT.
1 if tv comes on and shutsoff it is screen adjustment on flyback
