Its a personal preferance the best way is select factory default settings as a start then turn all your colour off & get the best black & white picture you can take a flick around the channels so that you don't just set to one picture as the bbc don't do a test card anymore when your happy add colour to suit you taste most tvs have a memory for your personal taste select if applicable hope this helps

Screen is really bright on dynex dx-l42-10a. Still show picture but bright no matter how it is adjusted. Was fine while watch TV & picture just got bright like the darkness quite. Any suggestions & what...


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

How do I turn up the brightness on my RCA Guide Gold+ Gemstar? (Thought I should specify what it says) Its a really old TV and I only have the remote, I figured out how to GET to the settings but whe


Check the remote control for its infrared emission. Check it with fresh batteries. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site in "Mosaic" or "Magazine" view. It will make surf easier.

If the remote control is found faulty, buy an other one. In most cases, the remote control will be faulty.

At first it was lots of horizontal lines over the screen, and later TV screen went completely black. The sound still is perfect. Perhaps I just need to replace the fuse? I love this TV! Thanks...


Hello
You have stated that your TV has a lot of horizontal lines before it went off picture. We say that lines as retrace lines. So many of them will there on the entire screen, at about one inch or so apart, horizontaly scattered along with picuture. At that time, you may be unable to down the brightness control also. Even though you have reduced the brightness control to zero position, there will be some brightness level on the screen. You should have to repair that fault at the begining. There is a voltage going to the picture tube base, known as screen voltage. That voltage determine the emission of the picture tube, and we call it a bias voltage. When it goes higher than normal, this trouble ie retrace lines will occur. In long run it may spoil the picture tube itself. I don't know what the case of yours.
Anyway it is best for you to consult an experience technician in this case. Ok.

The picture is really dark even though I have the brightness set to a hundred percent


brightness isn't brightness, its technically called white level, as for the fault, probably a power supply issue, also turn the brightness down as having it set to high can cause long term damage to the tube.

Well i really want to know what level the coular and brightness lvel has to be on a toshiba t.v


You can set these controls to your liking, though a lower brightness setting might increase the life of the screen. First, set the brightness and contrast to a level that is pleasing to the eyes, then adjust the color to look realistic - enough color without being disturbing. If faces area look greenish or purplish, then also adjust the tint (sometimes called Hue) until you get accurate flesh tone. Flesh tone is the best thing to adjust for; when you get good flesh tone, the rest of the picture will look great. ALWAYS make adjustments during a live news broadcast, which tends to have the most accurate balance of brightness, contrast, color level and hue. Note that commercials are all recorded in different studios with different settings, and will usually not look right - it's best to just live with this than to constantly readjust the TV. There are also DVD's available which walk you through proper TV adjustment.

Trinitron color is going out on each side but fine in the center


Hello vineinn2,

I would say that might be the problem, but it might also be a HV problem. I had posted this before and it might help you:

This may be a CRT problem. From what it sounds like i.e. dim picture, colors not bright. If you have a background in electronics I would tell you to check the voltage levels on the CRT pins and compare them to the values on a schematic, however if you do not have a background in electronics, I would suggest you taking the TV to your local TV repair shop and have them troubleshoot your problem.

Here is a possible list of things that might be wrong:

1) CRT going bad (The shop can try CRT rejuvenation if needed)
2) High Voltage on the anode not at proper levels (The shop can check this with a HV probe)
3) Video output levels low (The shop can check the voltage and signal levels on the CRT socket board, and on the video amplifiers.

These are the three primary possible issues.

I hope this helps,

Thank you,

Tooooooooo Bright


I would start by making some voltage measurements on the signal processor IC to see if the black level pin voltage can be varied. if not that might be the issue, but I have a feeling that it will vary so lets look at what else could be wrong. I know I harp on this circuit so much, but I have seen its failure so many times that I suspect it when ever HV issues occur. Inside of your TV there is a circuit that is supposed to shut the TV down whenever there is excessive HV pulses coming from the HV output of the IHVT (flyback transformer) if this circuit fails there will be an excessive amount of HV delivered to the anode of the picture tube, and this would cause the picture to become too bright. In addition this could be caused by a failure in the HV/Horizontal section of the TV in question. I would begin checking waveforms and voltage levels in that section if the brightness control on the signal processor IC is indeed working but not controlling the black level of the picture. I can not tell you what components are bad, just that you should concentrate on the HV/Horizontal section and the shutdown circuit for measurements. Get a schematic. If you dod not feel comfortable doing this take the set to a qualified TV technician.

Dark picture (HELP)


Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
