No picture no sound

Hi, Do you have a make and model number for this TV?

Hi Mike,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.


Kind Regards,

Mjsazon

The light is blinking a repeating error code. Try to determine the number of blinks before a slight pause as that will be an error code. Then respond to this same post and I will assist you with diagnosing what may be causing the set not to power up.

i have a philips tv model # 55pw9363/17f have sound no pic

this is either a power problem or the screen needs re-gasing

Its either blue tube or bad componet on blue CRT board hertes how to know disconnect Blue CRT board connect to neck of blue tube turn set on see what happens if set come on and plays then this lets you know if it is a problem with tube/video ic on crt board. If set shuts back off different problem.

Symptoms of a Defective or dying Power supplies on LCD TVs.

2. TV not turning ON properly.
3. TV turns OFF by itself.
4. Needs to be unplug to many times to make it work.
5. Humming or high pitch noise heard through speakers or at the back of the TV.

I repair these power supplies. Write to [email protected] if you require further assistance.

Hii...
Refere to Sony Blinking Codes :
5 Blinks ===> cause AKB circuit (AKB). Something is wrong with the video. check components on the C board, also check the A board. Also unit be in IK blanking, try turning up screen slightly.

Hope can solved the problem....

Yes I should be able to help you figure it out. First look on the rear of the set to check what the chassis number is. Should be an ATC 336 but it might be a ATC323 let me know the chassis number and we can go from there on diagnosing the problem

See my posted tip for the ATC336 chassis under my profile. Sounds like the capacitors on the power supply
