    thanks for your response. I am not an electrician. I did look at the components and did not see anything obvious, but I am not sure what capacitors are? I will try the 8-10 hour reset. Any other advise for a novice?

    not sure if I sent my reply correctly. Did you receive my response....if so, where do I go to receive your response on the web site. (new user)

  • jnjvarvaris2 Feb 06, 2010

    thank you. Is there any other visual inspection that I should do to determine if it is something simpler than what you suspect?

Hi


Thanks for using FixYa. This might have happened due to over-voltage. Please check the power supply unit for swollen/bulged capacitors and burnt wires/components on the power supply board of your TV. You should try and turn off the TV for 8-10 hours to reset it. 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. All this is only recommended if you have electrical expertise and know how to solder/re-solder components. Please do accept the solution if the issue is resolved or else revert for further assistance.



Thanks

    I believe its the power supply board that has gone bad and needs to be replaced. The cost of repair will be around $200-$300 including labor if you get this done by a professional. As I said blinking light itself states that the power supply has gone bad. Please do accept the solution if the issue is resolved or else revert for further assistance.



    Thanks

    May be you can take the back off the TV and blow all the dust off then inspect the power supply board and all the other boards for any blown capacitors however, still I would recommend to take help from a professional instead of doing it yourself just to avoid future issues. Please do accept the solution if the issue is resolved or else revert for further assistance.



    Thanks

No picture, no sound, but has power light...any suggestions? thx in advance


Do this first:


1: Check the antenna/cable connections.

2: Press the TV/VIDEO on the remote control or the TV to view a signal coming from another device connected to your TV, such as a VCR or
video disc player. You can select ANT 1,
VIDEO 1, VIDEO 2, VIDEO 3, ColorStream HD1, ColorStream HD2, or ANT 2 depending on which input jacks are used for connecting the devices.

*Be sure you have the right source to view video.

Try the above and post back before I can say there is a problem with your unit. If you have the user manual it's a good time to get it out. If you don't have it let me know and I will give you a link to obtain it. Good luck!!

Toshiba 56hm66 New lamp worked last night, wont boot up again


You now have a defective lamp ballast board. It sometimes is the root cause of lamp failures in these sets. The problem here is that Toshiba does not sell the ballast board independently from the larger, more expensive light engine assy. Call Best Buy back and get a servicer out there. He may have to take the ballast board out of your TV and send it out for rebuilding.

Toshiab tz43v61 power light blinking


I had the same thing happen to me 3 times and the first time it was 2 months off of warranty. It is costing me $395.00 each time, the TV is only 7 years old. Lets see I paid $2400.00 for the TV and also have another $1185.00 into it for repairs, and it is doing the same thing again. My suggestion would be NEVER buy another Toshiba product. I find it interesting that their website says "As a proven technology leader, Toshiba is committed to the goal of ensuring that, to every customer, the Toshiba name remains synonymous with lasting quality, durability, and value." WHAT A LOAD OF ****!!!

Model 55X70 Toshiba Projection tv


dont know about warranties but horizontal lines means your horizontal frequency which runs about everything has drifted off sync and if too high or low it will activate shut down circuits in high voltage and power suppy, even causing HOT transistor to short. good luck and call a tech.
