Panasonic 31" with pinkish hue	Can't Post

My 31" Panasonic Black Tube, which is approximately 7 years old (CT.....) suddenly started having problems. When turned on, the picture has a pink hue. This can last for anywhere from 3 minutes to 2 hours but does eventually go away. I currently is connected to a Panasonic VCR. I removed it and connected directly to cable. Still has the problem. Anyone with the same problem?

I think your Picture Tube is going bad. If you run it alot of hours, that would ice it for me.

if you know how to use a soldering iron...
UNPLUG TV FIRST
take back off of set.
on the back of the crt (tube) there is a small board with (typically) three heavy duty transistors. tap on the board lightly in all areas (while watching the tv, or have someone watch it for you) to see if you have a bad soldering connection, don't bang too hard or the crt will break. if you see changes as you tap the board, look for cold solders there are hairline cracks around the pins, looks kinda like this (.) make sure you have good light, and i use a 4x maginfying glass, it helps.

Thank you very much. Unfortunately I don't have a soldering iron but can get one. Funny thing is, after 2 months with this problem it has suddenly disappeared and the TV is working fine. It's been good for 4 days now. I'll still check it out. Thanks again!

Thanks again!!! You were 100% on the nose. There were actually 3-4 hairline cracks that needed to be soldered. All is well...
