I have one of these units, if the light is blinking and no picture as you have stated then you will need to replace the bulb in the unit. it is contained in the front of the unit behind the front panel on the right, you would remove the front panel after unplugging the unit, remove the single screw and pull out the box. replace it and then reverse the proces. the bulbs can be obtained for about $130.00 to $200.00 depending on where you get it from. Shop around.

Sony projection tv...Screen blinks on and off to black several times a minute...audio and everything else is fine


It sounds like either the inverter board or lamp are the problem. I would sway more towards the inverter as when the lamps die they normally do it properly.

I have a Vizio model E320Vl TV. after working for about two hours it shuts off. You can unplug it and wait about 10 minutes and it turns back on but will shut off again after awhile.


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My tv cuts on but flashes red light 5 times and shuts off


Those 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.

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.

I have a rca model led65g55r120q tv flickers and no sound


Check all cables for loose connection, try another input for picture (DVD, BLu-Ray, etc). If none of the other inputs work then it's a panel problem (display) If one or more of the others work then it's a problem with either the tuner or the signal.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
