Hello, I have a problem with my sony rear projection tv. When I try to turn it on the standby lights blink but it odes not turn on. I turned it on using display 5 vol- power and it did turn on and know it...


You need to count the number of blinks between the pause. Most common is 9 blinks. Also- after you press POWER, do you hear a "click" or not? If no click and 9 blinks, you probably have a "zero cross failure" and have two options:

(1) Replace the "G" board (part # A1054157A) or have it repaired (they repair it on eBay for about $40. You ship them the bad board and they either repair and return or ship you a different repaired board) A new board costs about $80- without having to send them your board.

(2) Repair the board yourself- by replacing the two diodes on the "G" Board - (D6301 which is on top- by the small transformer) and (D116 which is an SMT component on the bottom of the board- it takes VERY steady hands and a good solder iron). The parts should cost less than $25 and are available on eBay by searching for "sony a1054157a".

Where is the g board and how to i know witch one


Go to encompassparts.com. They are good about listing parts. Use guest login. Sony boards have the letters stamped on them. Just look for the one with "G" board. Some of the sony put a diagram on the inside to show where they are located.

Sony KP-57WS500


The flyback transformer is defective when the LED flashes 8 times. The FBT is located on the main board(D board).
Location of the part is T8005 and the Sony part number is 1-453-285-41
This part is available from this website.
This type of repair might not be a DIY due to the danger of working with devices that generate high voltages.

The convergence amps are the big STK's*** located possibly on the G-board in the sony. It is very difficult if you are not familiar with components and soldering, You can buy them at MCMelectronics, bluestar-online.com, Tritronics, VanceBaldwin.com, etc. Diagrams are online at fixya.com on the rightside of screen. Places like Manual.com or you can search the web. Hope this helps!
