TV turns off on its own

My VS-55707 TV also seems to turn off on its own and stays off for a period of time ten to thirty Minutes before it will stay on. Is it over heating somehow??

Hello,

Your power supply board is not yet dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


I hope this will help in solving the problem....

For some reason it started to take a longer time to warm up...


This model has several caps. on the power supply voltages such as the 5v, 9v and 12 v lines that begin to dry out and open and such problems begin to manifest themselves. Most likely this problem will continue to get worse and worse. As far as burned in images there is nothing that can be done short of replaceing all three picture tube and that is very expensive and this unit is to old to consider a 1000.00 repair.

TV shut off will not stay on.


Sounds as though you have a video problem. It may be the convergence chips. The TV is shutting down do to a default in the circuit ( the set knows there is an error of somekind so it shuts down to protect itself). This is a problem that needs a pro trouble shooter since it could be in about any board. Sorry I couldn't help more

Tv shuts off


When you let it sit for approx. 15 minutes it will come back on and usually stay on. I've also noticed that the color will fade in and out at times. during 15 mts of your sitting do you get sound & less brightness then problem in video or luminance section. if picture is dim & color will fade in and out at times then possibility of crt is getting less voltage on g2. if set is old then there is a possibility of crt getting weak. but if the above things are not there then problem in power supply. good luck

Set will not stay on


Better get this checked out by a technican. One possible reason could be coolant from the picture tubes leaking down onto the printed circuit board causing this symptom which could end up destroying the circuit traces on that board. Other possibilities include problems in the power supply or deflection circuits. If the set is over 8 years old, I would just replace it with a HDTV.
