Re: trouble in sharp t.v.

Good day.
Try to check if the fuse of your tv is busted. Also, try to look for any burnt parts.

Tv keeps turning itself off and the white in the picture looks alittle off.

To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

My tv would shut off automatically after turned

Unfortunately it isn't age that causes these TV's to fault, no, it is the actual Power flowing through them and the heat and stress this places upon every component in any unit. Unfortunately, electronic devices get destroyed by the very thing that makes it function. Either slowly, over time, or suddenly, from a Power Spike, or Surge. This damages the "unlucky" device that is plugged in and turned on. or as said over time the heat stress, and electrical strain, can cause a component to fail. slowly, bit by bit, over time until, it reaches a point, where it fails catastrophically. Well now you know how it all happens. My advice is to get a "Quote" for repair, and that way you can decide on repair, or replacement,

Panasonic CT-36HX42F I turn it on and then, turns off

It seems that the electrical relay's, it getting completed is not able to create the high voltage required for proper display. Hence on switching it on, the power LED will immediately light up but since the circuit is not completed it switches to standby and then off. Get the relays replaced and make sure you connect the main power chord to a 15 Ampere rating wiring usually the line meant for A/c and hot water Geyser(called as high power line)..........sodeep

TV remains in standby

PRoblem is in the start-up circuit for the high voltage power side of the power supply. The 5 volt, stand-by circuit, is obviously fine. Need to take voltage measurements on start-up to 32kv side of transformer to diagnose. Possible flyback transformer or voltage regulator.

Flashing power indicator

Sounds like a power supply problem unless there is a short in the deflection circuits causing the power light to flash. I'm afraid it'll take a technican to figure out what is wrong. If it's more than 7 years old, you might consider replacing it.

No picture No sound

This is an indication that the sweep power supply did not give the turn on pulse from the SMPS, thats the main power supply. If you know how to use a multimeter I will send you the instructions to troubleshoot this supply. Or you may need to trouble shoot the sweep supply as well. If you have no electronic or solid state repair experience, Please stay safe and call in a trained tech to assist you with this repair. Good Luck PS please rate this thread
