hi

Got Polaroid 22inch led tv number TLAC-02255, move tv to another room and turned it on. It did not turn on. no power,no standby light came on, nothing normally the red standby light comes on .

only had tv 6 months (no warranty got it from target clearance sale) ok nothing to lose i open tv up and checked power cable looked ok, checked capacitors and one was not right (a 100uf with 16 volts capacitor) so i changed it used a 35 volts one instead of the 16 volts one that was in tv.

checked the ir sensor board and when i touched the soldering parts with finger i notice the ir sensor (red for standby on blue for tv on)the sensor light turned dull blue sometimes i got red sometimes as well but when i stopped touching the soldering parts if went off, now the weird bit i put the sensor board down on the aluminum cover the hides the inverter with soldering joints face down to the aluminum and the red light came
on bright and stopped on picked it up and it stayed on so i tried turning tv on with button and the TV came on ??

powered off tv and tried again did not work, i on tried turning on again but could not get red light on but got blue dull flashing every time it touched the aluminum cover then after 3-5 times it would not flash, i turned power off then left it 10 mins and tried again, the red light came on and tv worked, but tried it many times since but no red light but i get the blue dull light coming on,any ideas what it could be i can post pics if want.

any help would be appreciated
