My t.v will nor urn on i was watching it and it just shut off


If no red light problem is most likely on the power board---set used up to 3 mechanical black power relays and sometimes they stick open or shut---follow cord inside and tap on them to see if one is causing the problem.

Tv wrks for 20 minutes, the the picture and sound shuts down


try cooling down tv with a fan to see if it stays on longer. if so, it's overheating. then to next step. feel for excess heat and look for dark areas on components inside. it may be obvious. if not, you may need to call a pro or replace the set. best buy use to do basic diagnostics for $25, but that was about 7 years ago

Our tv just turns itself after 10 minutes we can urn it back on, but it is happening more often all the time. The picture is great.


Replace the function switches. To see if switches are bad remove front grill and small panel if needed. disconnect the plug that goes to the switch board. You can use the remote to operate the tv. If the problem stops the switches are bad. Common problem on this set. Also swollen capacitors in the Digital module will cause shut down.

CRT Board


A crt board can cost from $25 to $40, the problem is that crt board should be tested before replacement, even if it is the most likely cause, there is always possibility that there is also something else (tube, main pcb etc.)

the problem may be due to dry soldering in the power supply stage if it was with the lamp there would be red or green light showing the presence of the power to the tv after making it own some of the components get hot and it will make the the soldering point conectionless and after some time the heat sink get cooled and the soldering point gets connected and u will see the picture again it is a simple problem if u have a soldering iron u make it hot and re solder all the components in the first part of the circuit board and the problem if rectified
