Dynex TV Problem

So I turned on my tv and have sound but no picture. I read some of the advice that was already posted, however, I don't know if the bulb needs fixed or if I need to do something else.

    Yes, I can turn the TV off and back on and all is okay. That is all I have done.

Try a "hard restart". which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent.
You can also visit the manufacturer's website or call their tollfree number for problem solving info.
Hope these suggestions help you out.

Sounds like screen voltage has exceeded much. Its LOT adjustments should be checked. Contact any service technician.

My TV picture becomes dark after a couple of minutes. If you turn it off and restart it it gets darker again in a couple of minutes. Any thoughts?


Check and replace the damaged component/s at its video output card, plugged directly to the back of the picture tube. Check all the resistors there for open.

No picture, no menu, black screen, no raster, sound ok


From your detailed description, it sounds that the main chroma processor IC has damaged. Raster means nothing, but the lighted screen that appears, when a TV is switched ON. For some brands, there will be a blue screen; when there is no signal input, and some others will have a bright white screen with some snow.
I advice you to contact any service technician, to get this TV repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

New dynex 24 in tv-working good but only shows 19 in picture. How to stretch to full screen?


Go into menu with remote control & change picture size. Depending on which station you are watching you may have to change it to suit your viewing preference. They transmit in different sizes

Cant see picture clear unless looking at eye level


I think you are correct. The standard def Tv is just poorly set up.

Look at your manual and see what the specs are for off angle viewing. I bet that the limit is right around 30-45 degrees. Which is not unusual for older low def screens.

The fix, unfortunately, is to buy a newer unit with better specs. The nice thing is....the prices are way down.

NO PICTURE, BUT TV HAS SOLID, SLENDER,HORIZONTIAL LINE ACROSS SCREEN


Your TV has a vertical deflection failure. There are parts that have failed. This will require time to troublshoot and service.

The make you are mentioning is not a known quality brand name.

You should get an estimate before deciding to service the set. The service cost may be expensive if there is no warranty on the set.

If you decide for a new set, I would suggest staying with a quality brand name and get a service contract.
