How to fix my Samsung tv ..picture goes in and out intermittently


The inverter board is responsible for the backlight so you can see the picture. If the picture just goes off intermittently then that means that the backlight is being turned off. And since the inverter board powers the backlighting you might want to look there.

Tv has no picture but has sound


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Where is the backlight inverter located in vizio sv471xvt?


Larger sets such as the one you have, will have two inverters. They usually are attached to the backside of the LCD panel on the left and right sides. If you don't see them there, then your inverters are built into your power board. If your power boards are either one of these below, then that is the case. If your inverter circuit is at fault, you will have to replace the entire power board.

Sharp LC-46SB54U Keeps losing picture intermittantly


i believe your tv is getting overheated, possibly from dust getting onto the electronic components inside. or the inverter board for the lcd panel inside is going bad, alot of times it is the capacitors on the lcd inverter board going bad.

Hello Robert, the picture tube on your TV set is exausted. Please contact your nearest Authorized Sony Service for further help/advice. After all, Sony is a good choice. The next TV set you buy could be one of Sony-s Bravia LCD. Kind regards, Arpad

Hitachi 23" tv/ toshiba vcr


Sounds like a problem in your VCR IF what your saying is when the screen goes dark and you turn off the VCR then the screen on the tv returns to normal?? Does this happen with the vcr on and the tape not playing?? No Ok you have a problem in the video processor Ic or the circuit but most likly the IC as Ive seen this already twice in a toshiba VCR. No if it happens even when the VCR is on but the tapes not plying and the vcr is sitting, and the screen fades The problem is the on screen disply IC in the vcr. seen this a dozon or so times already. Vcrs no a days are not worth the money to invest Unless you got a really good one from the past, BUT you can by a good on for these times for well under 100 bucks . Good Luck
