I can confirm that replacing these 4 capacitors worked perfectly. I work in construction so i am not a technician or anything. I did not even have a solder iron. I have photos of the board if anyone would like to see them. Took me about a hour to replace the 4. I had to use (2)35volt & (2)50volt cause radio shack only had 2 of each and it works like a charm. This TV has been in storage for 6 months until i found this article on the problem. Cant say thanks enough!!!!!!!!!!

SOURCE: Normal Picture Mode Not Available With Cox HD-DVR (Motorola DCH3416) and HDMI Cable

With an HDMI cable connected, the cable box determines the picture size. The settings on the cable box must be changed in order for you to get the correct picture size. I have some experience with Motorola cable boxes; usually to access the settings you turn the box OFF and then press the menu or settings button on the box to bring up the display menu. Hope this helps!

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

I GET NO PIC OR SOUND ON THE TV MODE, I DO IN THE HDMI WITH A ROKU BOX. I CAN'T SEEM TO FIND THE SETTING OPTION ON THE MENU TO RESET THE UNIT.


There are two types of reset to TVs. The first is simple to do; a Hard Reset; and the other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Does it work on the cable/antenna input jack? Can you get the menu screen to show up? If none of the inputs work and you can't get a menu screen to show up, then it sounds like you may have a bad YSUS driver board.

Service menu exit


1) Does your service provider (TV company) have HD service to your house and do you subscribe to that option?
2) How is your box hooked to your TV? HDMI or at least Component cables are required to achive HD modes.
3) Does the Roku box have setting that determine the output resolution?

TV doesn't recognize HDMI with Roku


The Roku is the problem, not the TV. You need to go to the Roku site and request download information to synch the Roku to an HDMI input.

Phillips 47" flatscreen sounds still


If the TV menu displays your problem is most likely not the Tv , but is caused by the signal source:
Cable box or connections. Reboot everything test using other sources like a DVD player to isolate the problem.

Flat screen to dvd connection help!


It depends on the TV.

On my Phillips TV this is switchable via the TV setup menu, and you get no sound with HDMI unless you change that setting.

The reason it's switchable is that the HDMI input is usually common with one of the component-video inputs (AV3 on mine). (cost saving move)

Thus if the menu is set to hdmi, then the audio goes thru hdmi. If it's set to 'component' then it goes thru the RCA patch cable.
