Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Sounds like a lamp error.... either a defective or broken lamp within the LCD1.gif panel itself, or you have a bad inverter.

SOURCE: PICTURE ON LCD TV GOING IN AND OUT

it works!! First i took off the front panel. Just check your manual for instructions, very easy to do. If you do not have a manual just down load one from google.. The instruction are easy to follow. The screw they have you loosen with a alan wrench is attached to the plastic, so you do not have to worry about dropping it inside the tv. Removing the lamp was simple. once out you will notice on either side are two small mesh screens. One of mine was 80% blocked with dust, the other side was only 30-40% covered. I used a vacuum to remove the blockage, i did not want the dust and dirt to go inside the bulb. i then cleaned all around the lamp. Reinstalled, and we are go to go. The kids are happy and i am happier since my wife not be buying a new TV.
total cost of repair $.00
time required to fix, less than 15 minutes.

Also when my TV was loosing sound and picture and then return. I did turn off my TV, then turned on. I nothiced a red blinking light. Mine flashed 5 times. After some reserch, 5 times is video related, bulb or video board. google red flashing light with the model you have and you will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.

hope this helps.

when your tv blanks out, turn off the tv and then it back on. below the power button usually flashes green light. does yours flash red? if so you need to count how many flashes. the number of flashes will help in resolving your problem. then google red flashing light sony and you will find what the red flashing lights mean.

SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

My Panasonic LED TV picture goes away after a few minutes


Could be a bad connection that disconnects when heat in the system causes it to expand. Take to a pro or call manufacturer, they might have a recall or free repair available.

I got a problem in TV. TV starts and shutdown immediately, while from sound its looks like that raster is going up but no picture, no sound. Red light is blinking. This happens only when i power off the tv...


Hi Sikandar,
Let me know how many times red led blinks as there would be an interval of 3 seconds so count blinks from pause to pause.
Is it Sony AR25M61 model or any other?
Above info will help to diagnose problem.
Thanks.

Problem is caused by voltage irregularity. Pulled plug for an hour and then plugged it back in. TV reset and it works fine. If this does not work it needs a TV technician.
