This television first started with the picture messing up, think that was to do with the cable connection on the back because I smacked it on the side and the picture straightened out and it was fine. Recently I went to turn the set on and it sounded like it was going to turn on and then it made another sound and would not power up from that point. I have worked on some televisions and installed fly back transformers, but that was long ago. I have tools, soldier iron and volt/ohm meter. I was thinking that I can open the set, discard the tube and this might have a broken connection to the cable but the power going out I suppose I could trace back from the power button. I am leery of discharging the set since I have not done this for so long. Can you instruct me as how I should do this and what to look for or test. Your help would be greatly appreciated

Re: television won't power up
Hi, The set has gone into protection overload status.
You must unplug the power cord for 3 or 4 hours and power it up again.
If the hard reset above does not bring it back to life it needs technical service. There are about 10 sections that would need to be checked to see where the overload conditions are causing the problem.
As a general rule this type of failure is severe and expensive. Typical costs of repair are always over $200 and most often closer to $400.
Common failures are main power supply, high voltage supply, deflection amplifiers and so on.
This is not a user or home remedy type repair. If you are lucky it may be something not so costly, but experience tells otherwise.
Hope this helps.

you should be getting both sound and picture..check the video cables in the back and make sure they are plugged in correctly...if this doesnt help, try messing with the settings on the remote...and after that it may be a component problem(picture tube blown, etc.
that silver box is called TV tuner (see picture ) ............ but in your case that is not the problem ......... after 4 or 5 yrs (depending on usuage ) in some TVs on mainboard & CRT tube's circuit board at some soldering joints cracks develops ... then due to loose contact TV behaves as you have described ........ when you are hitting that lightly on its side then these cracks at soldering joints are getting connected temporarly & for few seconds or minutes you are getting normal picture ....... so solution is most of the soldering joints on mainboard & on CRT circuit board has to be resoldered ....... only good tv service engineer can do this without shorting joints or damaging components..... so that silver box ( TV tuner ) is not the problem because when it gets deffective then you will get picture that comes when tv is switched on ---- usually it will be blue screen ......& also if you connect dvd you will get picture normally ...only thing is that you won't get picture from cable or antenna ..............
Hi,that is comme from your cable connector in the back off the tv /or its could be the tunner its self having a bad solder where its conecting pinfrom cable in to inside the tunner/pr or try another cable conector,
hope that help you
thank to ask fixya..
If you can see the cable menus then there is nothing wrong with your Tv at all. Reset the cable box by unplugging it from the wall for 2 minutes and then plugging it back in. This will force a reboot and you should be back in buisness.
The noise is coming from the fly-back transformer. By moving the cable connector you move the main board. Unplug the TV and remove the back. The transformer has a red wire going to a rubber cup at the top of the picture tube. Looking at the transformer you will see a dough nut shape with a metal piece going through it .. Drive some tooth picks between the dough nut and the metal core. That should reduce or stop the ringing.
only thing I can think of is for you to check your cables... assuming you are using a coaxial cable for the satelite and rca cables for games and dvds, I would recommend trying a different coaxial cable. There is also the chance that the coaxial connection on the tv itself is messed up. you may try buying an RF modulator that will convert coaxial to rca, most rf modulators convert rca to coax. so make sure it does what you need before you buy it. tech guys at store should be able to help if you can't figure it out.
