Re: dark picture on toshiba tv 32af44
This could be a few different things:
1- I would check the G2 voltage coming from the HV Transformer, if low, transformer is bad.
2- It could be your picture tube (CRT)
3- Find someone who gives free estimates ( good luck on that one)
4- If it is your transformer you might spend $200.00 for the repair, that's up to you of coarse.

> I have bought a pig tail that goes from VGA(the lap top side) to s-video/audio-video cables(tv side) A simple pigtail won't convert VGA to S-video. The VGA output consists of separate RGB lines and horizontal and vertical synchronization lines. If you have an adapter that really converts VGA (this output has no audio path) to S-Video and audio lines, then you probably just need to re-select the input through the TV's menu system.
There is a high voltage transformer(flyback) inside of this set that has two controls on it. One is for focus and the other is for screen control(brightness). You may want to try adjusting the screen control clockwise to see if that will help. The transformer is large, either black or gray, and has a thick red wire going from the top of the picture tube to it. It should be located close to the back of the set.I would try this first before I took it to the shop. Good luck!
you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again
looking on the back of ur tv near the cable input jack there might be an area where u can adjust the brightness on the flyback transformer. if there isn't you will have to remove the back of the tv and adjust it this way. PLEASE DO NOT TOUCH ANYTHING OTHER THAN THE BRIGHTNESS KNOB ON THE FLYBACK, CAUSE YOU MAY BE SHOCKED. so please be careful.
The green gun in your picture tube is set a little too high.
If you are experienced in removing the back cover of TV's,etc., you may try to find the drive and/or bias controls either on the circuit board that plugs on to the neck of the picture tube or mounted on the main circuit board of your TV. These controls are usually labeled. If you can find them, locate the green bias or drive control and back it down a little while watching the picture through a mirror. A slight adjustment may correct your problem.tJIS IS CALLED GRAY SCALE ADJUSTMENT.
BE CAREFUL THERE ARE SOME HIGH VOLTAGE CIRCUITS NEARBY. WORK WITH ONE HAND AND USE AN INSULATED TOOL TO MAKE ADJUSTMENTS
I hope this may help you.AGAIN BE CAREFUL!!
for this brightness problem actually came out from flyback transformer...so, before you spend and waste your money, try to adjust at back of your tv first. But if you aren't an expert, better ask technician to do because that transformer supply a very high voltage....there's two adjustment point at flyback transformer, one point for focus and the other one for brightness! try first...
You didn't say if you are receiving an off air picture or cable or satellite. The reason the commercials look good is because the local station (or source) transmits them "in the clear", that is, without any enhancements to the video signal. Network programing or local newscasts are sent through a device which inserts a reference signal in what's called the "vertical interval". You may have seen this as a series of flashing dots or pulses at the very top of the picture. There's a lot of information packed into the VITS (Vertcal Interval Test Signal). One of the lines contains a reference pulse for video which is set at a certain level. Your TV sees that level and automatically adjusts its circuitry accordingly. What I suspect is that your set is out of calibration and is pushing down the video signal because it is not "seeing" the level properly. A video alignment should correct this and can be done by a good repair facility. Hope this helps.
