Hello susbudi and Jazz617,

I would suggest do a check on the voltage from the IHVT to the High Voltage multiplier.
This will determine if this is a HV problem or not. If it is not It may be a video delivery problem which would have similar results. In any event both of these tasks I would suggest be preformed by a qualified TV repair technician.

I hope this helps,

Thank You,

My 48 inch Magnavox HD is showing double Model #: 51mp392h/17

If it looks anything like the picture (3D etc) it will need the "Convergence circuit" repaired.

Let me know if you have questions.

The tv is a Magnavox 51MP392H/17 and has sound but no picture. Any ideas?


TV is in high voltage shutdown protection mode. Check to see if Horizontal output transistor is shorted or open. If not then resolder all solder joints on HV transformer. If this does not fix it then you will need to do voltage checks off of H.O.T. and then possibly a bad HV transformer.

I have a magnavox rear projection 51MP392H turns on no picture or sound except for a little chirping noise sounds like its coming from the inside of tv


The chirping sound is an indication of a short on the middle board--the power/deflection board.

Someone needs to open the set and check for shorted parts on that board.

I have fixed several sets like yours with this problem and usually it is either a shorted transistor or another small part on that board. These are not the most easy set to work on---the entire plastic frame with the three boards needs to be put into the service position to check and look for the trouble.

Most of the MAIN boards for this set are not available--the only real chance for a repair is to trouble shoot the center board looking for something bad there.

I am sorry if I have not given you good news--but based on your description I think your problem is on the power/deflection board.

If you have questions or need advice let me know--I am here to help people.

I have a magnavox 52 inch tv the picture got a mirred look to it then went black but can still hear te sound can you tell me what's wrong


This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • No Audio / No Video - Makes Chirping Sounds

You can see some examples and find a fix here...

Magnavox


Need more info, does it click on and off, make any noises, was the picture going blurry, did you just move it, was in built into a wall where it wouldn't get air to cool???

Here is what I know about the 51mp392h this is a general post below I used for some other peoples fixes without more info on yours I suggest reading thru the below and links and add more info to your post so we can trouble shoot it.
51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

Audio only, no picture


Audio without video is usally a vertical or horizontal deflection problem with the DPTV chassis and Mag 1 chassis which is what you have. You may need a new deflection Large signal board. If you would like a link to one of those boards let me know.
