Toshiba 50H81 Re Blinking Light...wont work

This afternoon, I discovered that my Toshiba 50H81 has a problem. When I power the tv on, the red power light simply blinks. I called Toshiba and the friendly person who answered the phone told me that I needed service. Their assistance was overwhelming. (sarcasm alert) I contacted two local repair shops. The first estimated, over the phone, that the repair will most likely cost $350-450. The second shop was not very helpful and warned they might not be able to get parts because the tv is y yeras old. I searched the Net and found similar problems. Several people reported IC convergence issues and blown fuses. I took the back of the set and quickly realized this is something I cant fix myself. I welcome any feedback or suggestions. Is it worth fixing such a 7 year old tv?

    My 50H81 is doing the same thing, blinking power light. If I unplug it, it sounds like it is trying to fire up, then nothing but the blinking light.

    there are 3 fuses, I checked all via ohm meter with a good reading but still having the LED switch blinking. Any idea. Mine is TP50F60 about 10 years old.

    hi, I have the same problem here, red blinking light... purchased mine Nov, 2001, its been a good set up till now. I'd prefer to just fix it rather then going down the route of figuring out what to replace it with.

    Same problem as the others. Red blinking light no picture. Have had the TV for 5-6 years. Any ideas or where I can go to get it repaired or what is broken?

    I am having the same problem. I just want to know if it is worth paying to get it fixed, or just getting a new TV.

    I have a 55 Inch Toshiba - same issue but has worked for months but you have to unplug and then replug in and it works until the next shut down.  Then repeat.


    I have a tech coming out this week - any idea on the cost or likely diagnosis.

Mine is Toshiba 55 TZ, have it since 98', shutdown and red light blinking problem, search the net and found out, generally a Convergence IC (stk392-110) problem. bought 2 for $15 at suburban-elect.com (ebay). replaced following direction from http://www.casiasfamily.com/repairlog/tp50h15.html

Open back cover, 9 screws and wirings (pls mark), removed(soldered) a electronic board infront of convergence ic. removed IC (stk392-110) (screwed and soldered).

Replaced everything and voila...! it is now working again..
no more shutsdown and red blinking light. Saves me $400 for a repariman. of course just be careful with static and stuff.

I don't know how to solder, so I ask friend to do it for me. But I did the rest. Just to give you an idea that it can be done even if you don't know much about electronics. This in no way a recommendation but just stating my experience. Follow at own risk.

Red led blinking. tv wont turn on model number

Hi Rick,

First of all, thank you for posting your question here at Fixya.
My first advice is to unplug the unit from the outlet at least 30 minutes to reset itself and check if the symptoms still persists. If yes, may I know if it encountered before then there's some instances that the unit will power up after a few minutes of pressing the power button key?
Also, please double check the model number of your unit, if I'm not mistaken, it is 50H81 not 50H87.

No picture and the power light blinks

A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

Convergence issue, replaced convergence chips, now blinking red power light and no picture

Recheck all of your solder connections for bridging and cold solder joints. Check the large output resistors under the heat sink and the smaller ones to the left of them. Check all of the fuses on the power board. And make sure that you check all of your connectors carefully. Also check that you didn't pinch a wire somewhere.
I am not being mean by saying that if you could power up before then more than likely the power up issue was caused by something you did.
