TV is not powering up and red light keeps flashing

I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by:
- Unplugging the tv.
- Press several times (3 or 4 times) the tv Power button.
- Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!

I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster.
Good luck!

Cyndy, Yes this problem you have is most likly caused by the STR##### regulator IC in the power supply. You probably also have a capacitor or two that may need replacement and the best way to find those would be with an ESR type capacitor checker.. This is not a type of repair that a consumer with no TV experience should fool with. Please seek out a pro to assist you with this repair. Good Luck

I have the same problem on the same TV - nothing shown on screen, blinking red LED (sometimes slow, sometimes fast), clicking noise of a transformer. I got the TV free thinking I could fix it. It looks like the previous owner has replaced some resistors. Can anyone double check the pic and tell me if the mod is correct or not? PCB is marked PB9582 B Thanks

I have had this problem for about two years. The only time the flashing red light phenomenon occurs on my set is when someone (usually my father or my mother in law) turn the television power off and try to turn it back on again within a few minutes of shutting it off. Although I have not found a fix for this, you can avoid the problem by not turning the power on shortly after turning it off. I have never had a problem turning the power back on 15 minutes after I have turned it off, sometimes the time period is shorter, but if you don't wait long enough you run the risk of repeatedly turning the power on and off until the damn light stops blinking. It is aggravating but in seven years of owning this set I have had no other problems with it.

We just had the same problem, our TV was 6 years old. Repairman put a new IC in and it blew again (or shorted out) He told us that it would be easier to just replace the board, but that Toshiba board is no longer available. I hope we got correct information.

Replace the convergence IC. Had mine done by a professional for $200.00 and it has been working for a year now.

Okay i have the same issue with my Toshiba big screen it just happened on saturday. And i called the toshiba factory and they say it is the power supply. so yeah you would need to get a new power supply for you television set.

Have someone replace the stk ics and resolder the area around the ics tosh has a bulletin for resoldering this pcb altho the ics should be replaced due to age if you keep wathcing it it will eventually blow internal fuses then you will be the proud owner of a 55 inch piece of black particle board with a blinking red led on the front

I wish i would have saw this forum before i just bought one 57 inch and i love it for two weeks now i got a 500 dollar old particle board monster with a flashing red LED light.. lol it came bck on right away first time with a simple unplug, this time its dead i think.

Another solution is to check the fuses in the TV, 2 yrs ago our Toshiba 52" did the flashing red light thing, I simply opened the back, checked the fuses, changed out the bad one, and bam....no issues ever since :)

I have had this problem for a while now and I've fixed it three times before each one getting a bit harder to fix I followed the instruction on here for the third one but now I'm having the same problem and this isn't working any ideas

I have also had the same problem. Was told that it would cost about $500 to fix. Hard to beleive. Is there diagram or something that would helpin locating the IC's etc that need to be replaced?

I'm having the same problem... My toshiba theaterview just died... with red blinking light..

Okay everybody - hold the phone. Here is how I managed to 'fix' this same problem on my Toshiba tube TV (2005 model) in November 2014. I turned the TV off using the regular on/off button on the TV, NOT using the remote. It evidently put the TV in "standby" mode (I.E. THE FLASHING RED LIGHT...). Here is how to fix it ---- unplug the TV, unplug the cable, take the TV and put it somewhere out of sight, so you will not be tempted to throw it away, and WAIT 24 HOURS. (Seriously, I'm not kidding...). Plug it back in, hook up the cable, and turn it on using the on set power button. Wa-laaa! It works, amazingly enough. Evidently this 'standby' mode times out at 24 hours. It worked for me. TRY THIS - what else have you got to lose, but your TV. And from now on, turn your set off using the REMOTE CONTROL, as if you use the actual on-set power button, it can put the TV in standby mode. Anyway, it worked for me. Maybe I just got lucky, but this has happened to be twice before I figured out to wait the 24 hours to turn it back on and it worked. Good Luck P.S. Don't ever buy another Toshiba TV.......
