So what are you asking??? we need more info as there is no magic wand to swip and fix your problem. Im sorry i dont mean to sound harsh but what is it you are asking??If its what could be wrong with thew set if I told you would you understand the wordings or the electonic terms?? On this set its probably the horizontal output transistor is shorted there for the flyback is probably the reaso0n for the transistor falure . BUT the horiz. driver xformer could as well with cold solder joints but on projection tv's the coil burns open. YTour gonna need a schematic diagram to fix this Im sure and knowing how to read this schematic will help alot in trying to assist you in the troubleshooting of this set. Get a schematic and post it and i will certainly assist you in this repair !! Good Luck

It coming on and after a couple of seconds cut off

Without a brand AND model number or a better description of the problem, any suggestions would be nothing more than a guess.

Unless you are prepared to repair the TV yourself, professionally performed repair, even simplest ones, will probably exceed the cost of a new LCD replacement set.

Due to X-ray and other safety concerns (equipment and/or people), CRT TVs constantly check the voltages and signals required to make a CRT work. A few seconds grace is allowed during start up but after that, any excessive high voltage (real or imagined) or loss of beam deflection circuits will cause the TV to turn off.

Please do the following:
1. Move the TV to a quiet and preferable totally dark room.
Wait until night if necessary.

2. Stand within an inch or closer to the TV screen.

3. Turn on the TV and look and listen for the following:

a. Whoosh sound and/or head hair attracted toward TV screen
Yes. High voltage activated and charged CRT screen.
No. High voltage failed to activate.

b. Hissing or normal sounds from the speaker(s) while set is on.
Low voltage circuits probably okay. Defective low voltage regulator can cause high voltage to exceed limits.

c. Entire screen briefly lit up or single bright spot at center of TV screen

High voltage worked for a moment then the TV shut off due to over voltage or current problems.

d. Brief bright line from top to bottom or single bright dot on TV screen

horizontal deflection circuits bad
vertical deflection circuits ok
TV shut off due to bad deflection/sweep circuit

e. Brief bright line from left to right on TV screen

horizontal deflection circuits bad
vertical deflection circuits ok
TV shut off due to bad deflection/sweep circuit

It would be helpful for you to perform the above "up close and personal turn the TV on test" and report what happened.

Sony KP-57WV700

Hi. It seems that the g2 voltage of the picture tube is too high, resulting in a white screen, often with white horizontal lines. The g2 (= second grid) voltage is derived from the flyback high voltage. The voltage divider is mostly integrated in the flyback trafo housing.(including the adjustment knobs). A failure in this divider may lead to this defect. The static you hear may come from sparking in the divider. The flyback trafo is soldered onto the main printed cirrcuit board. Sometimes, one of the pins sits loose in the soldering pads.
Turn on the set and observe for any sparking around the entire flyback circuitry, and, or the flyback trafo itself
The screen turns black after a while, as a too high beamcurrent is detected. The set disables the flyback. Stand-by blinks meaning that there is a fault condition.
Be carefull with the high voltages. The flyback voltage is very high (20-30 Kilovolts !) and may be lethal !!

After turning on, my tv (21 inch CRT) produces peculiar rattling noise like high voltage sparking. The screen remains blank and there is no audio.

particularly that is a sign of leaking of high voltage in the secondary power supply or flyback transformer and should be corrected right away..check for emission of odor smell of ozone which is coming from high voltage leaks to make sure that it is definitely a high voltage leak...

When i turn tv on it gives me a picture for 1 second then goes blank, we still have sound

Hello

Sounds like you have lost video somewhere in the video circuits. Possibly the picture tube could have gone bad or lost filiament voltage.
You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as
the high voltage.

Goodluck

My question: My HP DV5000 is not displaying on the screen and it worked well on external monitor

You might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Screen will not brighten

Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.

Monitor is black

This problem is high voltage.Your monitor can not create high voltage properly.Or power supply can not create strong voltage.Change filter capacitor or High voltage transformer.If have warranty life you can change or repair it from where you purchase it..
