I have a 7 year old 40 inch trinitron tube tv (300+ pounder). It has developed a problem in the last year where the cable input bleeds through to any other input I have selected. It is the video only, not the audio. So when we try to watch a dvd or play a video game, the cable video comes through. If I unplug the coax cable, the snow bleeds through. Any help would be appreciated. Thank you.

My experiance is to not put money into a TV that is over ten years
old. TVs stress out their electronic components worse than almost
any other electronic product. After 10 years, there are so many
parts that are ready to fail that your are probably wasting your money
trying to get any more life out of it.
Another option is to wholesale replace the main board by sending it to
Module Exchange at 972-298-1212, or PTS Electronics
800-844-7871 ptscorp.com.
Be careful on buying a new one though. Often times, these new
technology ones are much worse. Always Google the model number of
the set you intend to buy and add the word 'repair' or 'complaint' to
see if it is one of the many models that are customer service
nightmares being produced by even the most reputable companies today.
Hope ya fix it!

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.

Look for the service manual, it contains the explanation of the flashing light codes, it will tell you what part is faulty.
