Re: Screen became dim over time and then blank. Red LED...

There is more than one flourescent tube in your TV, It could be possible that one after the other has failed, these should usually last a few years depending on usage.

If it is not the tubes then there may be a fault in the backlight inverter although this would more likely show up as a sudden failure.

How old is your TV?

How to replace a bulb

Depending on the type of TV the backlight will usually be either LED or CCFL. If the backlight is the only fault then the TV will still have sound and a bright light from a torch shone at an angle onto the screen should show a faint picture. Repair of the backlight is not a simple task and could be a number of different causes. LEDs are unlikely to fail in such a way as to blank the whole screen. CCFL tubes can cause the whole screen to go dark but replacement is very difficult. I would recommend getting a TV repair engineer to fix it.

When I turn on my 50" Plasma TV the light goes from red to green. The Green LED flashes 14 times then solid. There is a white raster but no picture or sound.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

I have sony Bravia KLV -32V300A suddenly shut-off while I am watching power indicator went off and standby red light blinking 5 times then after 2 seconds off then red light blinks again 5 times and so...

AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

MY SONY TV LCD MODEL KF-50WE620 screen went blank. When I turn on the green light it blinks on 40-46 times every second, then turn to red color to Stand mode and blinks for 160 times, then move to power...

There is no reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.

Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).

Sony KDF-E55A20 No picture or sound

The little flashing light down on front of your TV will tell you the problem by the color of the light or the blinking intervals, this is the reason you can not turn it off is telling you something. The manual should have a section dedicated to this part, most likely is the bulb, the bulb is easy to access generally hold by one or tow screws you can pull it out to verify the integrity of the bulb. Then again check the LED light before anything then you go from there.

Blinking Red Power Light

It sounds like the horizontal (H stop) and vertical (V stop) has gone bad. Check Cap 515 and 516. IC1509, Q1505 and the jungle IC, IC206. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC.
