It can be the power supply has gone out or it is in protection shutdown mode due to short circuits in the power supply or in the backlight inverter board, you will need to check the power supply DC output voltages with and without the backlight inverter board connected to the power supply.

Samsung lcd tv has sound but no picture. Samsung TV works for about 10 minutes then screen go black but sound continues


Use a flashlight on the screen when it goes black. If you can see a faint picture then the board that controls the back light has gone bad. If you see no picture then the T-Con board is bad. You can get replacement parts here: TV Parts Universal TV Stands DLP Chips ShopJimmy and fix the TV yourself. It's not that difficult.

No picture


Hit F2 to brighten the screen. No picture could be any one of these things you need to buy.

1. New inverter board
2. New LCD backlight
3. New power board/sound board
4. New Logic board

If the parts and repair labor becomes cost prohibitive, then look into a new laptop, unless your handy and can replace the parts yourself.

Red light blinking 7 times on Sony Triniton Wega TV


This means one of three things, either the lamp is bad on your tv, the ballast that powers the lamp is bad or the safety switch for the lamp door is not depressed or it has come un-plugged. It could also mean the power supply or fuse on the power board is blown. I am assuming this is a DLP tv, and if so, it is fairly easy to fix it or find parts for it online. If you are slightly mechanically inclined, want to save money and dont mind paying attention to detail then you can fix it yourself. If you need help dont hesitate to ask.

Kvg21q1 no picture no sound and led not standby power on........


Hi,

That's correct. As you have no picture and no sound, you need to replace flyback and power transistor.

What i would advise you that you can purchase the flyback and Horizontal output resistor online and you can also fix it yourself. That would help you save certain bucks.

Any further help, let me know.

Thanks for using Fixya.

Do rate the solution as "Fixya" if 100% satisfied.

Picture goes bad (fuzzy&scrolls&lines) on Hitachi projection tv


Sounds like your convergence modules have gone bad. They have 21 close spaced pins to unsolder and resolder. You'll need a soldering iron with a fine point tip and thin gauge solder to do the repairs yourself. Solder bridges between pins are common when soldering these module pins, so have some unsoldering wick handy if you're going to fix it yourself.

No Picture or Sound and chirping from rear


Most likely there are defective capacitors in the power supply. The chirping you are hearing is the attemt to fire up the supply. The cold may have been enough to cause the caps that were on the verge of failing to completely fail. This should be a simple repair for any shop. If you wish to attempt the repair yourself, let me know and I'll try to get you mode details on the likely defective parts.

RCA 32 in TV no picture no sound just a beeping noise TV power is on


The beeping sound is most likely the high voltage generator needing replacement. This is a fairly easy job if you have some tech support to discharge the picture tube. You can go to the following link and leave them an email with your model number and your symptom and they will email you back with the part you need and they provide free tech support with instant messageing so you can do the repair yourself. the HV generator takes about a half hr to replace and takes only the basic soldering ability. heres the link.
