When the light goes red it should be blinking a two digit code and repeat itself continuosly. slow blinks are the first digit and fast blinks are the second digit

Model 47PFL7422D/37. Why won't it turn on?

Check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

42HDS69 On off switch won't work sometimes

The clicks are coming from a mechanical relay in the standby supply for voltage---the standby power supply runs 7/24 if set is plugged into power.

What I would do if you are able is open set and on power board (power cord goes to it) look for and replace any filter caps that are puffed up there--the relay is possible but rarely bad in this way unless a solder connection under it is bad.

If caps are good you have a connection or bad part near the relay that likely is causing this problem.

Look closely at filter caps in power supply:


even one that is slightly puffed up can cause this, if find that and need to know what and how let me know.

I have a Philips 52PFL7422D/37 52" TV. For the last year now the TV will make a clicking sound like it is turning on but never does. After a couple of seconds to a minute the TV makes another...

I have the same model and the same problem... I am told the power display board is is the issue and may need to replacing. New board costs around $80,or a bad capacitor depending on your paitence.

My Sceptre LCD TV Power turns on briefly (blue

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.

42PF9956/37 SHUTSDOWN...

Ok. I got my tv back on.
I pulled off the back cover and found the relay that was clicking.
I have two blue relays next to each other that click when the power is pushed.
I placed a hair dryer over the relays for about a minute.
Once heated up, it only took 4 tries to get the TV to stay on.

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!!!
