Hitachi 32LD8700 - TV won't turn on although has power

Probably you should just disable the Standby feature, though it also depends on why it's in Standby. On some TVs, it's when it's been left on and idle for a certain period of time- basically the TV will turn itself off, or go into a lower powered state. It's possible it will not come out of it because the TV could be overheated, and needs time to go back to normal. Without know the specifics as to why the Standby happens I couldn't say, and it's also hard to say what the issue is with it coming out of it.

Go into the TV Menu and find Power Options. Set Power to Normal, or Quick Start (or whatever Hitachi calls it). If this is separate from the Standby Options, then disable the Standby option on its own.

It is with the fault to its main power supply regulator board itself. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

You require a new power supply board, it is a stock fault with this TV. You can obtain the part on Ebay for #36.00.

Hello
Do any indicator LED at it front panel lights up? If lights up, and the TV won't turn ON, the fault is with its internal circuit board. If not, the fault is with its power regulator board.
This is the picture to the power board to your tV.

Make sure you are not set to SAP mode...use mono or stereo.

Hi sir Jim!!!!



kindly check the 5 LED if there is lit lights to diagnose where the fault came from..You said the 5 led turn off for 1 -2 seconds it means no error but still won't turn on I think there sometime wrong on logic circuitry..




Try to read the voltages on highlighted words on picture of block diagram above such as vs,va,vcc,stby+5v,stby+3.3v,+5.5,+10.5 and +12v...

After that let me know the results to diagnose where the fault from..

Hope it helps...
