have fitted a new aerial as tv was connected to sky and now cant get any freeview channels keeps saying no signal what am i doing wrong

check open capacitor

Hello,

The first and easiest thing I would suggest is to make sure all the audio cables are hooked up correctly and securely.

Let me know if this solves the problem or not. I will try to be of further assistance if needed. Thank you for choosing Fixya.

HDMI BOARD NEEDS REPLACEMENT.. YOU CAN GET IT AT TVPARTSANDMANUALS.COM

Try website like Remotes.com to buy the tv original remote.

Hi,

first, make sure the Tv is correctly plugged into the wall. You can try another outlet. If that doesn't work, then your Tv is certainly having a power problem.

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.......

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes).

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.......

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

Yours sincerely.

1. Press OPEN/CLOSE
2. Press 3, 8, 8, 8, 3, X (X = 1-6 or 0 for multi-region)
3. Press OPEN/CLOSE
4. Power off

Try these these two site - 1. http://www.ehow.com/how_8335467_reset-vchip-sampo.html 2. http://wiki.answers.com/Q/Reset_v-chip_on_a_Sampo_LCD_TV

Serial ports are not meant for video only data communications if it is VGA port then your fine but the red white and yellow RCA connections are what you should be using this cable can be picked up at any local radio shack or walmart pretty cheap. As for the computer if the tv has a vga port connect it by that these vga are also cheap and can be found at radio shack or staples.

Hello

Universal remote codes for Sampo are
002 119 502 818
OK.

do a reset by going into your TV settings. You can also look in your booklet that came with the computer contacting sampo directly.

Try website like Remotes.com to buy an original remote or compatible to it.Around $30-$35 dollars for the original or very close to the original remote.Don't attemp used univeral remote on this brand Sampo is very small company and market share in the electronics devices,probally have no universal codes for this product.If u plan to buy those cheap unniversal remotes,by those eclectronic's stores or big box stores,for a after market universal remotes devices.

I hope that you have gotten this resolved, but if not, or if you have any other questions, here are the codes and some simple steps to run through.


1. Hold down the clear TV button until all lights light up at the top of the remote
2. Punch in a 3 digit code (provided below)
3. Press the # (POUND) button
4. Try powering the tv on/off, and the volume. If one or more of these functions do not work, start over from step 1 with a different code

Hello

Vertical rolling and overloading may be due to AGC and overgain we give into it. As there is no Tuner section the question of AGC Automatic Gain Control] doesn'e arise, as it is only for TVs has bothe tuner and video IF section. As per your specifications, your TV is only a monitor. For monitors, this type of fault occurs, when input signal is more than normal to its sensisitivity. Try to reduce the input signal by capacitor resistor network.
Make a connection with a 25Uf 64v capacitor and a resistor of 10k or so, parellesl to it, and feed the video thorugh this network, in series and check the effect. Use a capacitor of Non Polar type for this purpose. In most cases this must rectify the problem. You can vary the value of the resistor, to up or low to compensate the video level.
Video gain AGC inside the printed circut still not retifed, the video processing IC is damaged, and shoul be replaced.
Try these, and if you want any more asistance from me, get me through Fixya.
Ok

Digital Video In and Red Green Blue in?

Hi, I am sure we can help, but please provide the system number and make so we can check for wiring schematic.

are you connecting it to a cable box or straight to the cable?
do u have analog signal in your area? meaning can you watch tv without a cable box ? (where do u live?)
what input are u on the tv?
you need to consider all this b4 u start troubleshooting.
