Model VS 50501A TV. Works fine for awhile then screen goes black
This TV is 11 years old. Used about 3 hours a day. Now works for awhile, then the screen goes black. I think the sound is ok (hooked to several other speakers). If I turn it off for a minute, it will come back on and sometimes stays on for 30 min or so. Sounds like something is overheating to me. I am not a TV repair person. Can I fix this or do I need to get help???
Yes, we have the same exact problem but it is now getting worse. It is doing it more frequently and sometimes won't come back on for quite awhile. So far it will eventually come back on after awhile and will stay on for 30 minutes or so and then go black again.

The most common issue here in the old sets is bad solder connections--the problem is you have to get the entire chassis free and up so bottom of boards face rear of set---look to power supply---a lot of 2 and 3 lead parts there from heat come loose from the boards and also to the middle of the set on the middle board.
If you are not able to attempt this the set is too old for a shop repair in my view as many parts for it are no longer available.
Hello Hello It is due to some loose soldering points [dry soldering we say it technically], in the power supply section of the TV. Just check for it. Check the solderings of all components, that will heat up to an extent when the TV works on. Repeated heating and cooling may make solderings to the terminals of that components to get loose. Just resolder all the suspected solder terminals, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. This must solve the problem to your tV. OK.
Sounds like the verticle circuit is failing a honest shop will take of this for you around 180-230 if you want to do yourself youll need a iron and some filters and an verticle ic
This model series had a odd problem that caused this. It was the Hoizonal wire connctors for the yoke. If my memory serves me right, the Yoke wire harness went from Yoke to Yoke and plugged in at the casing of each yoke. What I found is the solder connection on the small board of each Yoke was intermitent. Please be careful if you choose to tackle this. It is in a HV Area.
Hope this helps,

Good Day, qfd333;
To find suspected liquid the PCB's, remove the front speaker cover and the small board held on by 5-6 screws. Look at the first 3 to 5" on the PCB. Use bright light it's not always easy to see. If fluid is spotted remove the boards from the back of TV. Use small brush, like old tooth brush, and acetone. You can get acetone from hardware stores
Look for rusted wires or parts and replace as necessary.
Good Luck, big IRISH.
Check the vertcle yoke pins for solder cracks. Check verticle output circuitry resistors and transistors. And also check for Coolant leaks from the CRTs this happens alot. Check capacitors for any signs of sweeling or heat as well.
