Question about Standard (CRT) Televisions
We have been given an old (at least 13 years) JVC TV. The first time we switched it on it worked well for about 20 minutes but then cut out and went to stand by. After pressing a button to get it back onto the channel we were watching, we got sound but no picture, for about 30 seconds before it reverted back to standy by again. On subsequent days, we managed to get about 5 minutes of viewing and then the same thing happened. Any thoughts on what we should do next? Thank you. Happy new year.
label on back is torn which is why we have only a few details of model/serial
as you say that color came back for 15 minutes then went off. this is a clear indication that there is a loose contact or pcb crack somewhere in color section only. if that happens to be ok then check 1 antena or cable socket loose 2 loose connector in color section 3 print open or crack near chroma signal processor. 4 loose near color control. 5 chroma ic night be defective. if you are not tech person take the help of tech.person.

It could also be the color wheel, it's been documented for DLP TVs to have problems with both the lamp and color wheel. For those with a screwdriver and ability to read online instructions, you can replace the color wheel yourself. I took out the guts of my Samsung HLR-5067W and found that the color wheel shattered, I'm anxiously awaiting my replacement.

Hopefully you have the problem solved.
If not, the RCA plugs, listed as input 1 and 2 are shown on channel 91 and 92.
I recommend connecting the DVD to either input. Turn on the DVD. Then run the auto programming function of the TV. It will find and program the channel for the DVD. Then use the channel up or down on the remote you are currently using and you should find a working DVD.
Hope this helps.

if you have back ground of tv repair, remove back cover but you need tools and tester, check heater line from crt ckt board going to horizontal section.
