4 blink error for that model is i2c communication failure specific to ssb (small signal board) if intermittent should upgrade firmware to newest firmware and if constant would need to replace small signal board

Your TV main board is damaged and you need a new one. You can order one on ebay and fix it yourself. Make sure you have the TV model/serial number on the back label of the TV to have the right part when ordering.
i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?
hey crs246, I have the same exact problem with my philips tv same model. Have you gotten any help that you can share with me. Any help would be appreciated.
I don't know why but this got my TV on.
I took off the back cover and found the source of the clicking.
Two blue plastic rectangular relays in the exact middle.
When I pushed the power button, I felt the top relay click, and I saw a flash from the bottom one. (they are right next to each other)
I took a hair dryer and placed it over the two relays for about 1 minute and tried the power.
It clicked only 4 times and then came on!!!!!!!!!
For some reason heat helps the relay.
If anyone is a tech and can explain this, please do.
Good luck!!!!
My tv is on and it didn't cost me anything.
I just can't turn it off now!!!
