Top 20 Proscan PS50700 50" Rear Projection Television Questions & Answers

I could be anything but mostly it will be its age, and if its never been cleaned out it could be the bulb failed, power board. dust build up can cause over heating of the parts. even damage them if the dust becomes damp. is there any lights flashing or any leds lite up ?

I dont know how to fix it, only had the tv for 3 months already having problems doesnt say much for proscan!!

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.

No, and it is not real easy to get into the advanced convergence menu to do it. A a question: on rear of set aside from model number is there a chassis number like PTK195?

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. http://en.allexperts.com/q/TV-VCR-Stereo-1749/Proscan-PS50700-projection-TV.htmIf not this model let me know.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, and a list of Dealers for spare parts, as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

There will be lots of TV repair places that will have one if you remove the broken one as a sample.

I hope this helps.

Replace the audio output chip

Hmmmmm. at the easiest point i would certainly find a bad capacitor or two. Alwasy suspect a 160 volt to 200 volt cap at 1Mf, 2.2Mf or 4.7Mf. Another suspect would be the 200 volt 100Mf caps that are somtimes used in theses TV. You do have a problem in the the horizontal section. Start with the capacitor check and check for bad grounds. It is the board that contains the high voltage transformer [flyback]. It is this board that will be reworked. Ask a tech, you have some knowledge of the problem and this will keep your cost of repair in your favor. Your proscan TV is a sister model of the well brand known brand, RCA! Hope this helps and thanks for asking!

I have the same problem with a 40" Toshiba LCD, Component cables work fine with FIOS but not HMDI, goes in and out then blank. HDMI with DVD player works fine. Best buy reported this same problem from users with this toshiba lcd but no solution.

I'm having the same issue with our proscan 61 inch rear projection. It was made in 1997

Hi there.
Try to unplug the tv for about 10 minutes. It might reset itself.
Iceman.

Well, that's the front panel button.Try pushing each button until you know which one is the cause.Actually,you need to find someone to replace this button, because to replace this button,you need to open the TV case, that's why you need an expert to do this.

Hope it works!!!!

According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

adjust voltage G2 Screen. thats why have retrace line. resolder also CRT board.

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.

I recommend buying the Monster LCD cleaner with the soft cloth available at Walmart or other retailers. There are cheaper LCD cleaners, Make sure to buy soft cloth or microfiber cloths to clean it. Spray lightly on screen and wipe off.

You need a professional to align the convergence. it's a big job if one or more tubes have been replaced.

clicking is from the relays -- sound like the power board went out--

go to partstore.com

the front trim pops off and behind that there are screws that hold the glass in place. once you remove the screws you can access the screen and clean the tubes.

Hi, sounds like your closed captioning is turned on, go into the menu and look for "CC" or "text" and turn them off, video-tek
