My 36xbr800 blinks six times then pauses then blinks six times, this is repeated......

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, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. To get more details, http://electronicshelponline.blogspot.com/

Just count the number of blinks occur at one time. 14 blinks to trinitron TVs are not possible. It might be 10. If so,

1. Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board. If you wish to know more about blinking codes to Sony Trinitron models TVs, check this link. If it is Intermittent problems? This is a great feature. 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. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.

   
   
   

A lot of these are not getting fixed as very heavy set--typical repair in our shop is usually over 150 dollars and goes higher in some cases.

If the red power light remains and blinks look for the number of blinks and then a pause and repeats that ---if so that is an error code.

Most common failures in this set are on the D board--D for deflection.

That means no horizontal output which could be caused by a faulty driver stage or even a faulty power supply.
Hope that helps.

If it's any comfort we are having the same problem

The standby light should be blinking a repeating count with a 2 second pause between counts. Can you post hte count here please? That will help to determine the effected circuit and the solution.

Thanks,
Dan

6 blinks is usually the D board

I get a black screen after power on...then a bright white light in the middle of the screen.Then the red light flashing and turns it self off.
