Hi and welcome to Fixya,

In most instances, there would be a blinking LED light. The sequence and number of blinks actually represent a particular error code. With the number/sequence known, then what section or general area to begin the diagnosis would be pointed.

Pls post back number/sequence of blinks. Further, pls confirm if you are considering a DIY (do-it-yourself) amd stage of familiarity with electronic components & circuitry use and availability of a DVM/VOM and a soldering iron.

Good luck and thank you for using FixYa.

Audio but No Picture!


Unless you are absolutlyey sure that the value is correct on the resistor replacement I would put the original back in if it still checks good. I could not get you a Service Manual, but I do have a nice trouble shooting guide that I can send you. I just need your e mail.

Toshiba 61hx70 picture bounces and goes in and out of distortion


Most likely bulbs are failing and dirt and dust are caught up in cooling fans and in the projector of the set.

No picture is it the bulb and is this hard to change?


You DO NOT have just a bulb in your set. You have the older style Projection TV with three picture tubes. It's a good possibility that you have a convergence issue that has blanked the raster and therefore you will not see a picture until the error is corrected. Have it looked at by a qualified technician.

Blurred picture


Sounds like a resistor in the convergence circuits or covergence amp ICs them selves. Usually the ICs will distort the picture. My guess would be the flame proof resistors near the ICs 1 or 2 may be oen. Let me know if you need anything further.

Picture red and green not lining up on my Toshiba 61HX70


Repair will require technical and mechanical skills.The red convergence IC will need replacement,which will require the chassis to be removed.After IC change,alignment in the servicer menu may be needed.Go slow--Remember, above all else,do no harm.You have a great tv,so my suggestion is get a senior tech on this one.

No picture/no sound


If you have the ability to remove some of the connectors to the main chassis & flip it over so you can see the chassis from the bottom, inspect the solder connections around the power supply and near the high voltage..the flyback area, you could have a cold , cracked solder joint or several of them due to age of the tv. Use a magnifer & bright light to try & spot them, resolder & put the chassis back together, see if this helped.
