I think this blinking is an error code. Either consult the user manual to find out what it means or go to as mant Philips forums as you can find to get the answer. I will say that I think you have a fault on the line output stage. Either dry solder joints or the line output transisor or transformer is faulty. Hope this helps.

Power light but no picture or sound


Hi!
My name is Chris.
I have this Phillips Wide Screen TV that didn't have or come with a remote, so I had to go out and buy a universal remote for it today from a BIG W Store. I'm having some technical difficulties & problems with switching and turning it on, but as I use the universal remote to turn on the TV, I'm having a bit of a slight problem with it turning it on, Ok, Yes, it works and Powers on, but there is nothing showing or giving me the indication that there is no picture or sound showing up on this Wide Screen Phillips TV, But there is a little red & green light at the bottome right hand corner that keeps on flashing red when ever I use the universal remote to switch the power on. Is there a possibility, that i can get some help on here, to help me out with any suggestions, is to why I'm not getting any picture or sound showing up on this TV with this universal remote ? Is there anyway that i can maybe get some help with this to help me out with solving my issue with the Phillips Wide Screen TV ?

Phillips model#42PF7320A/37 no picture ,no sound red light blinks 7 times


Hi tileman5,
Your 7 blinks (error code) means that your 8.6 vdc in the power supply section is faulty.This was sense by the standy-by power supply's initial test. This voltage is easy to locate in the power supply board, each output voltage is written in the board itself. Concentrate in its regulator circuitry. Look for open fusible resistor, shorted transistor and leaky/dried capacitor. The unit is disable unless you fix this 8.6vdc fault.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

No sound, no picture standby light blinks 5 times, pauses, blinks 5 times, etc. This is a Sony Trinitron 36" Wega tv about 7 years old.


  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Phillips flat screen won't work


First, eliminate the possibility that the power cord, itself, is not faulty. Try another power cord from, say, your computer, or something else with the same type of power cord. This is often overlooked
