Question about Toshiba 50H81 50" Rear Projection Television

1 Answer

Lite in the front of the TV when you turn on keeps blinking and no picture.

I unplugged the TV power supply cord and reconnected it after a little while the light still kept blinking couldn't get it to come on. After setting up a small TV which works fine with the satellite connection, the next morning turned the big Toshiba back on to see if it would come on and play, it did for couple of daysday then went black again with the blinking light have done that twice now by leaving it sit overnight and again it worked fine. it is working now againthis but don't know for how long before blinks again.

Q510, Ta1316 is your sync processor and probably the problem you're having here. It's a common one for this unit and you could pull the board and check the solder connections it has with the foil - - but you may need to replace it...

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

Lite in the front of the TV when you turn on keeps blinking and no picture.

The blinking is giving you an error. Even thou you say your TV is working fine, there is something wrong. It could be anything from the convergence(like Color problems slightly out of line) or Sound problems, or you may have problems just in the power supply. Could you remember the set acting funny like in the past? If so do you remember what went wrong or what gliched? This could tell you what is going on now. If none of this it could be a capacitor in the Power supply.

I have a mitsubishi wd-62525 the power light keeps blinking, and i can't get picture. i unpluge it than want 2min than it stop blinking and i can turn to tv on and get a picture than after 30-40mi

Good day!!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

The power light is just blinking red on my panasonic 1080i hdtv. cant even switch it off using the power button. picture and sound come on for about a second when the tv is switched on after power cord...

The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

Sony kp-65wv600 projection tv error code. My tv blinks 7 times.

The Standby LED blinks when the TV is turned on, then shuts off when the picture is displayed. If the LED blinks continuously, this may indicate that the TV requires service. Before getting the TV serviced, try power resetting the TV and factory resetting. Try the below steps also: Connect the TV to a different wall outlet and check if it helps. This is to check if the issue is with the Power. Disconnect the TV from the Power Strip or the Surge Protector and connect it directly to the Wall outlet and check if it helps. To Power Reset the TV, disconnect the Power cord for a short period of time (approximately 1 minute). Then, reconnect the Power cord and power ON the TV. To factory reset the TV, turn it ON. Then while holding down the RESET button on the Remote Control, press the Power button on the TV front panel. The TV will turn OFF and then turn ON again. Then release the RESET button to complete the reset procedure. If the issue persists, service may be required.
Good Luck!!
