Clicking numerous times before turning on


This sounds like a very common issue.

If set is hard to turn on (takes several tries)but will eventually turn on hereis what my guess would be.

Every set has a standby power supplythat is running 7/24 if the set is plugged in and it supplies voltage to theremote circuit that turn on the main power supply for the tv and hence turn theset on.

This is an area where companies cut corners by using lower rated voltage caps.By this I mean Standby usually provides under 10 volts to trigger the seton----what they do is use filter caps rated at say 10 volts max in a circuitwith 9 volts (example)=with the standby on all the time the filter caps(electrolytic caps) dry out and fail.

The problem usually begins where you have to turn set on or or two times andgradually gets worse--takes longer and more tries to get it to come up.

Once on it will stay on until turned off for a period of time.

The caps will begin to work better (regain some of thecapacitance) as they get hot--hence one it is on it will seem ok.

The beauty of this problem is most of themhappen when set is a year or two old (no warranty) and all you have to do islook at the top to locate bad ones.

They are generally black or blue and round and vary in --they have twoconnections each--a + for positive and a - for negative--not unlike a batterywhich in a way they are. The + and - are marked on top and bottom of most boards.

They are easy to replace and not expensive parts.

The tops are silverand metal looking with creases on top and if bad they will be puffed up ontop---tops must be perfectly flat with no brown material leaking top or bottom.

If this is your problem once you id them (make a drawing) you can begin.

Here is the critical part---on each cap is also marked the value like 220uf 10vdc---220 micro farad at 10 volts maximum.

If you find for example 6 puffed up and all are 10 vdc replace them with thesame value capacitance (like the 220 uf) but go up to at least in this case(from 10 volts) to a 16 or higher rated voltage cap.

The only issue is when you go up in voltage rated value the cap is larger sosometimes there is an issue of physical space for the replacement on the boardto fit them in.

The reason they cheapen these sets in this way is if 10 caps and you make25,000 sets there is a considerable savings in parts cost.

They do not care as long as it lasts past the usual one year parts warranty.

I have taken the time to be long winded because this really sounds like it maybe the problem you have.

See attached photo of a typical cap and if you have questions or need advicelet me know.4_19_2012_2_18_56_pm.jpg puffed up caps that are bad.

Turn off after a few hours


If the TV turn itself off then perform the following steps:

(i) Check if the Sleep timer is activated.

(ii) Check if the Parental Guide prohibits viewing during that time and/or limits amount of viewing time per day.

(iii) Check the batteries on your remote, low battery power may cause random signals from the remote.

(iv) Disconnect all the cables from the TV then reconnect them after a few hours.

(v) Ensure the power cord from the TV is directly connected to a functional wall outlet.

(vi) You may also try resetting the TV to the original factory settings by pressing the Reset button on the remote control supplied with the TV when in Menu.

The following is the information indicated by the blinking patter of the standby/timer lamp on the TV:

2 times : Power does not come on.
Load on power line shorted.

3 times : The TV has entered standby mode.

4 times : Has entered standby state after
horizontal raster.
Vertical deflection pulse is
stopped.
Power line is shorted, or
power supply is stopped.

5 times: No raster is generated.
CRT Cathode current detection
reference pulse output is small.

6 times: No picture

9 times : No sound

Furthermore, the TV is equipped with a self-diagnosis function that you can use to determine whether the issue is related to any hardware malfunctioning. Perform the step given below to run self diagnosis:

Quickly press the remote command button in the following order from the standby state.

Display -------> Channel 5 ---------> Volume -(minus) --------> Power ON.

If the Self Diagnosis display numeral "1" for any parameters then a fault has been detected and service will be required.



wish u good luck!!!!!!!!!!

When turn on tv with remote and without remote it


I have the same tv. Something to remember is that the picture is lamp powered. It takes about 30 seconds to power on and takes about a minute to fully power off. I had issues when trying to turn on the TV, accidentally double tapping the button, which would turn it back off. I'd do the same when trying to turn off the tv.

If you are sure this isn't the issue and the lamp light is still on once the tv turns off, most likely your bulb is burnig out. You can find replacement bulbs on the internet. They are fairly easy to install yourself, so you shouldn't have to have the tv serviced.

If the bulb seems fine, your tv could possibly be overheating. In that case, make sure the vents are cleared as the tv gets pretty hot.

Remote became unuseable. Tried system reset button numerous times. Currently unable to use front panel controls or remote to turn tv on.


Almost hate saying this but in your case it applies. Unplug the TV from power for a couple minutes and then plug it back in. Also on the remote itself make sure when you are pushing buttons the the "TV" button lights up indicating that the TV is the device being cotrolled. If that doesn't work go to the MFG's website and look for answers there 1st...hope that helps you!

The constant blinking green light means that the TV is not booting up. This is a common problem on this set.You need to remove the shield from the DM board (standing upright on the left where the DTV RF connector is)and inside you will see the four leaky capacitors (1000 MFD 16 VOLT)replace them,plug the TV in and wait 70 seconds for the blinking light to stop,then turn on the TV.The hard part will be removing the board from the TV(lots of screws and connectors,takes time)

Sometimes resetting the microprocessor circuit is all it takes to fix a set. A shock, power fluctuation or something in the timing of the control circuit may have caused a momentary glitch in the television and resetting it fixed the set. Keep an eye on it and if there is another problem with it, reply here and we will try to work it out.
