I have a Protron LCD 26" TV model#LT26CIPI...The tv was working great turned it off on night and in the morning turned it back on to sound but no picture just a Black screen...when you change channels


Since its a LCD take a flashlight and have the room as dark as possible and with the light look to see if a very very faint image of the picture can be seen or not---many of these sets use a "back light" for the brightness and if that's not on.......

Screen does not lighy


If you look very closely, is there an extremely dark picture, or a solid black screen? If it's an extremely dark picture, you just need a new backlight. If it's a black screen, you either have a bad connection (broken, shorted or unplugged cable), or need a new LCD. Let me know, and we'll go from there.

Screen will not stay bright


That's the battery saver feature of that Philips portable. If you use an A/C power adapter, the light will stay bright.

Hope this helps!

GPX PDL705---Picture very dark


Sounds like the back lighting of the LCD screen is faulty. Is it a new unit - take it back. You might try the brightness and contrast controls and turn them up. If that doesn't help it needs to be repaired.

No picture on screen


Hi,

Initially, this would either be a defective LCD panel or its interface. A way to verify is to play the portable DVD using an external video monitor such as your TV. If still gray or blue screen (no video) even in the TV/monitor, then it would be the video interface/circuitry. If the video is displayed, then it would just be the LCD panel display.

If it turns out to be the LCD display, it is very possible that it is a backlighting issue. Most likely, it would be in the inverter and/or CCF (cold cathode florescent) lamps. This is a relatively easy repair by re-soldering. It is perhaps more of a task to open the panel lid/cover of the LCD display.

This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Image dissapears but there is sound


My sister owns this unit, and like other users on this post, her screen quit working on her. She brought it over to me to see if I could fix it before she tossed it out. I first hooked the unit up to the TV with supplied A/V cables to see if the unit was outputting video. The unit supplied video to the TV fine, so I figured the problem was with the LCD screen or the connection from the unit to the LCD.

Like another user on this post, I noticed that the video would come on for a second or two when the small depress button was pressed, but then go blank again. (This button is at just below the LCD screen on the base unit – toward the middle of the base unit. You can see there is a small notch on the LCD screen that fits into this depress button when the unit is closed. This allows the unit to know when the LCD screen is closed.)

Here comes the fix that worked for my sister’s unit – I hope it works for yours also. . .

I decided to reset the screen to the factory settings through the setup menu. This is difficult to do when the screen is blank, so I figured I would have to go hook the unit up to the TV again in order to see the setup menu. Well, I had already put the AV cables away, and I felt too lazy to dig them out again. I decided to just navigate the setup menu by pressing the depress button on each menu, which the second or two of video would give me ample time to navigate the menu. Once I was in the first setup screen and depressed the depress button the screen came on like it had been doing when I was trying to view a movie, but low and behold it did not go off like it had been when trying to view video. Since I was in the setup screen I decided to reset the unit to factory default. I then exited the setup and played a movie. The screen did not go off. I have tried to get the screen to go blank again, but it stays on. It sounds like the problem is not with the LCD screen or its connection, but rather with the operating software of the unit. It is a piece of junk, but it is working for now. I hope this helps with your units also.

I also noticed some users posting a problem with an upside down screen. Hold down the mode button and the screen will cycle through different settings … one of which is upside down.
