The red power light is on, on my tv but the tv will not turn on.


Look for bulget capacitors everywhere and replace even also all the 10 volt types. to 16v and 16v to 25v samecapacity but if thereare 330 mf types change for 470mf .

if you have a model with models of good looking green colored 3 watt resistors sometimes there is one for power circuit to the tuner or some place change it for standart vishay 3 watt models because the end caps can be invisible falter at some point even if they are not have a brown discoloration.
and sometimes KEEP CLEAN the vents at the top of the back and place it not tight fit in an too small closet
because of heat build-up.
I estimate maybe your Samsung is between 4 or 6 years old or even younger , control even for loose solderings on active components (with heatsinks) but also on the fuse resistors that sometimes are conna get loose you see by a little manipulating of them.

I have a Samsung Model HLP4663WX/XAA Tv Picture great, but it keeps turning off. I turn it back on and it will only stay on for a min then turns back off HELP!


Hello ma'am, hi, looks like the tv has problems with the power supply board, parts inside get to fail slowly, those are likely resistors, and capacitors, and active parts like transistor gets to go leaking, eventually they will be permanently to fail. so have it checked by a tech guy.

SSP-R4232 Plasma TV, blue light on, but tv wont turn on.


At this point it appears that your main board is probably bad. You most likely have a 5 volt scource going to the main board but its not powering up the set. The main board is part number BN94-00796A.
You might want to have a technician look at the TV to verify this as the issue before purchasing it. Please take a few moments to rate my answer. Thank you.

Just baught a new lamp and all that is happening is lamp light...


You will need to reset the lamp counter.
Begin with the TV powered off.
Point your remote towards your TV.
Press:
Mute + 1 + 8 + 2 + Power.
Your TV set should now say “Loading Factory”.
Browse down to “Option” then press Enter (or the right cursor button).
NOTE: The Mute+1+8+2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can subsitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you’re having difficulty with the ENTER button.
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterwards!).

Playing the sound of tv through the sound bars speakers


Not sure for the playstation etc, but for the TV the manual says using the (not included) optical link between TV and the main unit.

Note that this is not mentionned in all language versions of the manual.

Got samsung le37a456c us as monitor


This samsung as pc monitor has an easy solution. after trying everything on many different sites:- rebooting, locating tv in settings, all the different sequences of conecting and turning pc and tv on, resolution settings. all this was a complete waste of time. SOLUTION:- i read all these people with the same problem and many had tried laptops and pc's on same tv yet always using same vga lead. so i decided i'd look at problem not in pc or tv but the lead, i borrowed a vga lead from I.T. department and as soon as i plugged this lead into my samgsung tv my pc option was active and i'd not even connected pc at that point. so i know its a total lead oriented problem.
