More than likely its is a faulty component on the power supply, like a compositor. It is cheaper to buy a new tv then to fix many of these issues. Repair usually involves a lot of diagnosis and if it is a replacable component you will then have to solder out and back in the new part.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy. http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Hello apostolos,

If you are using the powersave (monitor off) feature, the video signal to the TV is switched off and it may not be picking this up again automatically. This can also happen if you switch the TV off. In either of these situations, you should be able to switch the TV display for the PC on again by holding down the FN key on your PC keyboard and pressing F5 once.

This key combination is standard on most PCs for switching an external monitor on and off but on some PCs it may also be F4. If neither of these are correct, look for an icon of a monitor on one of the function keys on the top row of yourkeyboard - or use the "Display Settings" or "Monitors" Control Panel (depending on OS) for switching external monitors on and off.

You may need to press F5 a couple of times while still holding down FN key to get the monitor configuration you require, e.g. PC monitor off and TV on, or both on.

If you are using an animated screensaver, the TV should not be losing the signal from the PC, but this can still happen if the TV is switched to standby or off.

If you can't get the TV to pick up the signal from the PC using the FN + F5/F4 combination, it might be a good idea to reset the TV to factory defaults and run the TV setup again.

Hope this helps. If you need any further assistance with this problem or instructions on re-setting your TV to factory defaults, please reply to me from within this page.

Regards,
BElectric

Swap input 1 and 2 and see if you get same result - could be a bad tuner in the set (#2).

What is Pd 2171? This must be a power supply problem, so if you don't have a red light flashing then Check the Power board and see if you see problems

I have the same problem. It happened once before about 4 years ago just after I bought it. I put a DVD in without the power on. I was able to take it out and it worked fine. This time my daughter put the DVD in, I took it out but still no picture or sound.

Have you had any luck?

Hi


Thanks for using FixYa. If the TV isn't turning itself on then the fault protection circuit has detected a fault and has turned down the TV. You'll need to check various things to find an answer which part is bad. Please check these---

1. Check for signal cables at the back and also try unplugging the TV for 8-10 hours to reset it.

2. Swollen /bulged capacitors on the power supply board-- This happens due to overheating of capacitors.

3. If the capacitors are fine then you'll need to check for connectors on all the boards and also the fans if they are working fine.

4. Make sure the lamp connections are fine and ballast is not burnt.

Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition, so please be careful.

Try to reset the TV by unplugging it for 6-8 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Same Problem Here on different Toshiba Model. Did you get it fixed?

Unfortunately you are right it is the display panel going bad. You can either live with it or buy you a new tv as the panels usually cost as much or more than the tv. Sorry.

I have th esame proble, did you ever figure it out?

Hi there
Make sure the settings are correct by setting them to the TV not an external device like a home cinema system

Good luck and thanks for using Fixya

no, the tv has a setting that auto changes the screen ratio. you can turn the auto screen ratio off in the settings section. Once you have turned it off put ratio to 16:9 and it will solve the problem.

your tv needs to be repair again power supply problem or circuit.good luck.
