** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

I have a Sony KDF-60XS955 tv. It won't power on,


I have that manual. There are three lights to the left of the power button. One is labled LAMP. The manual states "The projection lamp, which illuminates the picture, has a limited life. If the screen becomes dark, the color looks unusual, or the LAMP indicator on the front of the LCD projector TV flashes, it is time to replace the lamp with a new one (not supplied). Use a Sony XL-2200 replacement lamp (not supplied) for replacement. Use of any other lamp may damage the LCD projection TV." I also found in a different page " LAMP LED lights up in red when the lamp for the light source has burnt out." I guess burnt out would be extream. I found one other if you had opened the light bulb cover and didn't close it properly. " If the lamp cover is not reattached securely, the self-diagnostic function may be triggered and the POWER/STANDBY indicator flashes three times." You can down the sony manual at http://www.docs.sony.com/release/KDF60XS955.pdf

Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

In your case the led flashing is indicating protection mode. That usually indicates an internal fault.

Follow the full troubleshooting below:

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

Power on TVgoes on and off by itself and now will not come on at all


Ok this is an LCD tv. I don't have any experience with Sanyo TV but a common problem with many brands are swollen capacitors in the power board.

Call the company, they usually have a back door route. We had a nice Viewsonic 42" LCD TV at work and they had us push something like vol + power to remove password, then we could put in a new password.
