My Sony KV27TS32 the other day displayed a funny picture, turning it off
and on restored the picture for about 2 mins. The sound is still working
correctly. I took a picture to better explain this. Is the tube gone?

A bit of history of this TV. I changed the 3 trans and resistor on the
powersupply about 3 months ago.

Thanks everyone for your help!

kip,
Thanks for your response. I resolder what I think is the posistor. No
luck. :(

Is the black box with the red arrow pointing to it the posistor?
Thanks!

Check the resistance of the degauss coil... maybe its open.

When you first turn on the TV do you hear the degauss energize ?

Sorry for the double post, I refreshed the page on accident.

I don't know where to check the resistance of the degauss coil. I know
nothing about TV sets, I thought i just give it a try with my little
knowledge on electronics.

I do hear it energize. It makes the same sounds as it did before it
stopped working. Only now I get the funny red, green, blue swirls.

Thanks again!

tapping on the side of the set restored the picture. I opened it the set
and lifting the side where the posistor is restores the pictures. If I
lift up and hold the board the picture is perfect. Looks like a bad
connection somewhere, resoldered all the joints but still a bad connection
somewhere. :(
any thoughts?

Thanks for your help kip.
