I have a sharp tv. it stays on standby mode. LED lights up. i already resolder the whole board including the jungle ic. fly back is good

Do a hard reset to this set, and check. 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.
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
Type in the brand name of your device, in the search box [at the top right] of the display window, and press enter to get all related posts. It will make surf easy.

Cable female adaptor is missing

The small metal box is the tuner. The tuner has to be removed to replace the broken off RF connector. The connector has to be soldered to the tuner housing (metal box) and the leg of the connector has to be soldered to the circuit board, board has to be checked for cracks or if it is broken. If board is damaged the tuner will have to be replaced, if its available.

Cable input connector broken off

Usually the connector or at least a new connector can be put back on. If there is minor damage to the board, a tech can repair it in most cases.

Sharp 27sc260 27"

If you have a cable box you could bypass it to make sure it's not the cable box. It could also be the input to the TV channel has been changes so as not to be on the right channel from the cble box. Is the TV on channel 3? Or video input? and did you change anything that would have caused this in terms of cabling? If not it seems to be a TV menu issue we would hope.

Hi this is relitively easy to do has the port come disconected from the board if so take the back off the telly but make sure it has been switched off for more than 24 hours so that their is no electricity in the tell as they store power for upto 24 hours.
Is the old port damaged or has it just come off the solders.
If it is damaged you can buy these from any repair shop for next to nothing and fitting them is easy as all it is is two bits of solder you will need to unsolder the bit that have broke on the board.
Once you have unsoldered this you will see where the new one fits and how it fits.
Solder the new one in make sure its in the right place so that it comes out of the whole in the case at the back as getting this wrong will mean redoing it again.
This should be easy enough for anyone to do as long as you got soldering iron and some solder.
The only thing i will say is make sure you only solder where it need soldering if you get it wrong you could short the whole board just make sure you only solder the two parts that need soldering this should be easy to do let me know if you have any problems ok

Sony with diagonal lines

Is it a composite(yellow plug)video input? an HDMI input? What if you switch the output of the cable box to another input, Make sure its not the cable box first. If it happens on another input then the cable box or the connection wire to the tv from the cable box is bad.Good Luck Ps Please rate this thread

Atenna plug pulled out of tv, how do i get a signal now?

It has always amazed me how many "F" connectors get pulled out of tuners. I know because I've replaced hundreds, usually successfully, saving the cost of a new tuner. You need to unsolder the tuner from the board and remove the side cases. If the tuner board is not damaged beyond repair, (if it is you have to get creative), a new unit can be soldered in place. Put everything back together and you will be in buisness. New "F" connectors can be purchased from MCM Electronics at, part #215543 for $2.50. I always use a new connector as the old ones are usually trashed. Reliability is compromised if you don't use a new one. Technically you do not need the cable hookup since you have composite inputs. For my money I would just hookup a VCR (with a tuner) coming out of the VCR composite jacks into the TV composite jacks and use the tuner on the VCR leaving the TV in Aux, or whatever they call the composite inputs, and call it a day. It's you're choice but using a VCR tuner is faster, easier, cheaper and if you want to play a VHS tape you're already hooked up! If you are a traditionalist and want the TV 100% remember to be safe while working on it. Good luck whichever way you go.
