Image is double like ghosts with a greenish/redish color

Not a lamp as this model (one listed) uses 3 picture tubes--likely a convergence problem--see typical in attached photo.

This set does but rarely have this problem---take a careful look on back where model number is at and look for chassis number--is it a PTK195 or what? That chassis had one easy fix for this problem.

I have a 50 inch proscan and it just beeps but will not come on how can i fix it

I suspect wrong model number is listed here as this set makes no beep at turn on; older set made around 2000 but if it is your model here is some information to look at.

If not this model let me know.

Why is the picture showing in red, green and blue colors at once and how do you get it back to the regular color?

if it looks like 3 pictures at one you can try the convergence in the menu if that doesn't do it then the convergence circuit has gone out

No Sound on ProScan 50" Rear Projection

Check that sound is not "Muted";
Check that speakers are not turned off;
If using a S-VHS component, remember to connect the components L & R AUDIO OUT jacks to the TV's L & R INPUT jacks.

Hello, Greetings from Hamilton Ohio. I have a 54 inch Hitachi rear projection television and I believe the bulb is getting ready to go because it takes about four or five minutes before the picture comes...

And greetings from York PA!
Ok I have read what you were saying about your TV and after much consideration I dont think its the bulb because a bulb does not get better as it warms up! (most bulbs that are bad get worse as the TV warms up!) But capaciters do act this way when they go bad (stable when they warm up!) so I would have to say the control circut has one or more bad capiciters on it and will need replaced!
I hope this helps greatly!
Please rate this answer!
thank you!

Picture problems

Sounds like a problem in the main power regulator circuit, such as a bad capacitor or regulator IC or transisitor. There are no user serviceable parts inside these sets and every thing is soldered into place. I recomend that you call in a trained service tech to assist you with this repair.
