The tv will not turn on the front panel blinks but no picture or sound

U have problem in ur TV. I would suggest calling a mechanic.

Hi,
If standby light on tv is not blinking that means tv needs power up command either by remote or power button on tv itself.
Press Program +/- button on tv front to turn On tv.
Thanks.

You have bad switches on the front panel. Press them 50+ times to release them. Failing this you will have to replace them. You can disconnect the front panel to confirm this.

what does the tv do when you turn it on does the front light blink?or does the tv power up but sound and pic are absent?

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.

REPLACE LAMP

i unfortunately cannot help you with your problem, but i have a question, how did you disconnect the front panel?

Red light blinking means there's a problem in the TV....

What kind of tv is it?

check the horizontal transistor

I have a Sony KDL40S2000 and three months out of manufacturer warranty my TV made a clicking noise similar to feedback in a bad sound system and went to black screen. The error was not recoverable and four blinking lights were seen by a technician. I bought the extended warranty from my store, so I was covered. After one month in the shop, the technician brought my TV back today and told me the panel was replaced which would have cost me 1000 dollars if I wasn't covered by the store warranty. I read on another site the four flashing lights can mean a bad inverter. I don't know enough about TVs to tell you if the panel and inverter are one in the same, I just know you need to get it repared if you get four blinking lights at a huge cost!
