If the TV "goes out" meaning that you lose tuning (picture gets very snowy, disappears totally, etc.) but the power stays on and is otherwise normal, the trouble is often because of bad connections inside the tuner.

It is possible to remove the tuner from the circuit board, open it up and resolder the connections that typically go bad. (Usually they are solder joints connecting the ground traces along the edges of the tuner circuit board to the metal box it mounts in, and some other ground points on the board. Often they are visibly cracked.)

To this requires electronic soldering skills and the tools to make the repair. It is possible to do additional damage to parts because of small connections, fragile parts and so on), so this may not be something you want to try as a first project. But if you can do the soldering and are patient, it is possible.

On the other hand, if "going out" means the set suts off completely, there are too many things that might cause this to offer any suggestions for things you might try on your own.

It shuts off on its own will


something is getting hot and a fan could keep it cool and it might help to keep it running.longer . I have tv shop and ones like your that come on are hard to fix unless it fails all the time,I would suspect cold solder joints on board and is fixable but wait fot it to fail all the time before you get it fixed

Hook the cable to the back of the unit.. Go into the customer menu and make sure you've selected cable (as opposed to air). Then do an auto-program and that should solve the problem..

Four blinks would normally indicate a yoke winding that was shorting intermittently, 5 blinks something on the "D" board in overvoltage condition and 6 blinks commonly Ic6501 is failing...
To have all of these blink codes happening could be signal derived, thereby not affecting dvd play. Could be smps related or possibly regulation. My first guess would be the "D" board...
Is there a cheap and quick fix, yes and no... This isn't one you'll be able test out or you wouldn't be asking the question. But a shop should be able to determine the problem and repair for less than half the cost of a new Tv in it's comparable class..
Hope this helps!

We hooked it up with another DVD player, no difference, We used another TV, worked good. We changed all the cable cords, and made no difference. It comes right down to that TV. yes from aboe it is 100% sure that trouble is in tv. every channel is blury and has a trail. it is due to focus of your tv is not ok 1 adjust focus control 2 focur wire going to crt base might be loose due to some foreign material deposited on crt base. 3 defective crt base. 4 if tv is old there might be possibility of crt getting weak. hope this will help.

Turn the set on, hook the cable directly to the TV, take the remote control and press 1 - 1 and if the TV tunes in channel 11 then your set is fine. If the TV was autoprogrammed when hooked to a cable box then the only channels that will be stored in memory are 3, maybe 4 and AUX. To correct this simply go back into the menu and look for the "autoprogram" option and perform the autoprogram while the cable is directly connected to the TV, without a cable box.
