My tv turns on properly but after a few minutes it goes blank

you are having a heat related issue and the component or parts are failing. using a hair dryer blowing into back of set will make it black out and a portable fan should cool it enough to come back on. unless you know a good cheap tech, repairs are costly. i left the business when t.v' s became disposable.

Focus the picture on a Model 27GT619 Television

The focus control is on the flyback transformer (Usuallly black or brown with three wires coming out of it. The bigger wire goes to the pix tube with a rubber cap at the end.) The focus control is on the side. There are two. The top is focus. Good Luck!

RCA 32" TV - Model #32F531T - Faded to black

Isolate filament voltage from CRT,i.e. unplug Crt socket from pix tube.Measure filament voltage on CRT PCB.If present,suspect bad pix tube.If missing,solder any/all connects in filament circuit,meaning CRT board first then main PCB.

Set-up screen keeps popping up

This might not be a solution but it is a suggestion,your set by now has many loose conections this is as true as your name Less,I would suggest to go in looking for loose conections and overheated ares,while you are looking check the horizontal driver transformer and make sure all 4 legs are solid,this is only as a preventive maintenace,as far as the reason why is doing what is doing I got a feeling you will find an intermitant conection.If you are not familiar with tv service be safe and call for assistance.It should not be expensive.

Sony KV-32V35

Could be a problem in the shutdown circuit,in the HI Voltage detection circuit,or the flyback transformer. If your not a tech, you shouldnt be experimenting by adding parts as its going to knock you against the wall if it bites you. You should start out with a service manual and check the voiltages as now thinking it could be the power supply voltage regulator also. Please call a pro to assist you with this repair. Good Luck
