Your TV seems to turn off when it heats up.

Try to check for bad solder contacts on ANY component (wires, connectors, resistors, coils, etc) and resolder if any, also check connectors for dirty / oxydized contacts and clean them if necessary.

The components that tend to heat up are the ones most likely to have a bad solder contact. The circuit board around these will be of a darker colour.

These can be: power resistors, power diodes, power coils, power transistors, voltage regulators and other components located near to or connected to these.

Also check the electrolytic capacitors, if any are bulged or blown at the top, replace them.

It may as well be a problem elsewhere, a partially damaged or burnt out component that fails when it heats up, i just suggested a few simple things that you can check visually and i really hope you can find out what causes the trouble.

Samsung screen goes grey with green letter? Have Comcast cable


When the green letters appear, turn off the cable box only.
If the screen changes, the problem is in the cable box or hookup.
If the letters stay, there is a problem in your TV.

I need help , hooking up my samsung HT-Z410 HOME THEATER, TO MY LG HDTV, SO THAT WHEN I'M WATCHING REGULAR TV THE SOUND OF THE TV CAN COME OUT TRUE THE HOME THEATER SPEAKERS, CAN IT BE DONE? CAN A COMCAST...


first of all here is a link to the manual....http://downloadcenter.samsung.com/content/UM/200802/20080220095448484_HT-Z410-XAA.pdf and yes it can be conected thru your comcast but you wil need to buy probably cheapest at wallmart an RF Modulator (Less than 20 dollars) and from your cable box (vidieo out, or to tv) install the cable to the rf mod unit (ant in) and that converts it from coaxial cable to rca (meaning a cord with yellow ,red,white push on connectors) plug the red and white into aux input on surround system (see #3 on manual view on backside of surround unit)and and you got it.It your tv does not have a yellow vidieo connection (which is where the the yellow plug into tv)in the back then add a coaxial splitter after the comcast box so that the 1 coax line goes to tv and the other coax goes to the rf mod then thru RCA cables to the surround sound.you may need to buy xtra cables but they are cheap. hope i helped........you may try asking family or friends for the above equipment i described.the newer tv's dont need it and many people have this stuff layen around...good look

How do I connect to Sharp HDTV and Comcast cable


Your dvd recorder only has rca, red white yellow inputs it wont allow you to record in HD, although you can play your comcast box any hd, regular digital through and record. Hook up the comcast box if HD through preferably HDMI if not get one from comcast. The HD box is the only box that allow HDMI, component and regular RCA and some RF out. This way you can play HD to your set but also record through RCA or RF again will not allow for HD record unless its TiVo. Hope this helps

The only time I have had issues like this was because of the Component Cables not being in the right position (the Red and Blue connections switched), or a bad Component Cable where the Blue Connection is not receiving a signal. Swap out the cable to be sure and double check that it is properly installed. Green to Green, Red to Red , Blue to Blue.
Hope this helps,
