Tv stays standby mode


There are a few possible reasons
1. Line scan has failed - line o/p transistor
2. Frame scan failed (unlikely)
3. Power supply problem/chopper transistor
4. (and hope it's this because all you need is a soldering iron, good lighting and soldering skill) Dry joints or cracks around line output stage

I have sharp 25inch ctv model 25FN1DX/51. The problem is when I switch on set within 3 seconds it goes to standby and green led blinks 6-8 times I hit some dry solders and replaced the capacitors in power...


These blinks indicates a fault to its main board. To know more about these blinks codes, check the site linked here. The horizontal output transistor should be checked for short [collector to emitter OR collector to base]. If this has happened, when you switch ON the set, its system control will detect a short circuit, and will shut down the set. If you wish to get some details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Timeslide / Flipcard, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

SHARP 29" TV switching off to Standby


have you tried changing the batteries just to elimate this problem

change them

sometimes if the batteries are low in electronic devies, they send a wek signal to its receiver (your tv),

your tv gets confused and then switches itself to standby

if you have changed the batteries and this problem still persists

it can only then be th PSU or power supply unit, take it to your local tv repair shop of mastercare somewhere like that, its going to be cheaper to get it repaired than replacing the whole tv

PSU'S generally 20 to 50 pounds depending on model

don't deo it yourself though unless you've got a capacitor discharger (or a nice 25KV will be on its way to your body)

hop this helps mate, let me know how you get on
