Red light blinks in 5 times then pause and then repeats. It is the lamp error. " Lamp Driver Defect"
When the "LAMP-PORT" (pin 95) is low, the lamp is not turned on. If the "LAMP-HV-DET"(pin 96) is low at the same time, it is classified as no high voltage of the lamp driver. I'm guessing it needs a Lamp driver which I think is on the C Board, which is part of the "Optics Unit Block Assy. The C Board cannot be orderd separately, and Optics Unit Blocks are not cheap. Good luck

Sony KDF-50WE655 shuts down - red light blinking 4 times

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.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

TV turned off by itself and now blinks red led 6 times

6 blinks means a low B error. Which is no DD 6volt output on G1 board . This will cause no picture and no sound. To fix this yourself you would need the manual to get the correct sequence to test and proper part to order. You can get a service manual for 10.99 at the following link and they will ask if you'd like it emailed to you after purchase. Here is the link,

Sony LCD television will not power on.

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
