Having the same problem with my SONY Wega, 57"... If you are able to turn the TV on, DO NOT SHUT IT OFF... Instead, on your remote control, just shut off the cable button. This will turn the TV off and you will be able to turn the television back on when you click the CABLE button only. Don't do what I did and mistakenly hit TV and Cable. I'm unable to get the TV back on again. Grrr!
I have a palsonic flat screen digital TV For the past 6 months its been a bit of trouble, but nothing like it has been going just recently in particular this week where its been out 5 out of 6 days so far. I've hardily been able to watch it. I've only had this TV for 2 years. I dont have a set-top box, its all built into the TV unit. This annoying problem can be like this for hours if not days, then when you least expect it, BINGO The red standby light will come on after many attempts with my remote, but tonight (Friday) the red standby light is on after I turn it on but wont go off standby to green
Whats the problem
My sony hdtv flatscreen (46 in) will not turn on. It actually turns on for 2 seconds then a buzzing noise occurs and the standby button blinks. Any ideas????
I had a 32" Panasonic LCD that would take several tries to turn on. My first attempt was with the remote that came with my Comcast DVR. After that didn't work, I'd manipulate the power button on the actual tv --repeatedly pressing down on it until the red blinking light went away and a steady red light came on--signifying the tv was on. After doing this for what I'm guessing was a few years, I found it it needed a firmware update. My brother downloading the update onto an SD card and updated my tv for me. It hasn't had a problem since.
I had read online about Samsung's power on problems and those (for the most part) were due to a faulty capacitors in the power supply board. I thought this might be similar to my Panasonic's problem too. Then I discovered the firmware update and that took care of my problem.
Maybe there's some info in here that might help you.
Here is the information I gathered about them:
Samsung LN-T-4665F will not turn on. Red button flashes and TV just makes clicking sound. I've unplugged both the TV outlet plug and the power cord. Great picture when it worked however I've only had for 18 months and would not expect it to be having this problem.

There are 2 capacitors in power supply that are bad. They will have a bulging top 1000uf @ 10V.

sounds like the power supply board has failed. VERY common problem
The main board or power supply has problem. To make sure which one causes malfunction the TV must be opened and check by technician. You have one or two bad caps in the power supply these can like devices will be puffed on the top from venting the value is written on the sides replace them and you will be good to go
Here is clue, most Samsung LCD TV power boards are made in China, probably the components on the board are also Chinese made. Samsung LCD TVs in China market have same problem and the power board business in China is blooming. The rebuilt power board price in China is around $60.
Back to USA, the power boards sold here are not brand new either, there is a $50 core charge in each board purchasing.
Tips:
When replacing the defective capacitors, installing good quality ones, like ones made in Japan, USA or KOREA. No kidding, if the power board is made in Korea, most consumers may not have this problem.
Also for long run, choose higher voltage rate capacitor, for example, the original capacitor is 1000nF 10V, upgrade to 1000uF 25V.
Blinking 6 times anyone have ideas what could be wrong?????
Do you still have the manual? It usually explains what light codes mean in the back, in the troubleshooting section. If you don't have it any more you can probably look it up online with the model number.
other than replies that are guessing or an answer Nothing to do with "MY" problem, is there Anyone with CRT TV repair experience, repairing Sony CRT TV's especially with these standby blinking codes like mine that starts with 5 blinks after plugging it in then going to 7 blinks? If a repair is under $200. & will last for a couple of years I will have it repaired; If it's going to be a lot more money I will just try & find someone to take it off my hands & invest in a flat panel. Thanks
I was able to fix my Sony 50" Wega with the similar issue of the blinking red light and a brief horizontal picture (intermittent turn on that got progressively worse). I fixed it by unplugging internal connectors and reinserting. I also reinserted the projector which brought back the clarity. Contacts oxidize, by reinserting you clean the contacts. Touch up solder connections on the power board and make sure to wipe your iron on a wet sponge to keep it clean.
