Re: Crestron TPS-2000L with Sharp LQ5AW136R panel



Thanks. I would need to strip it down to get those photos. There's some info on the panel [URL="https://www.panelook.com/LQ5AW136R_Sharp_5.0_LCM_overview_10315.html"]here[/URL], but no pictures of the boards inside.

I was hoping to get a steer based on others' experience on the likelihood of it being fixable. If it's highly likely to be the LCD matrix itself, rather than a discrete component on the board, then probably not much point in spending the time to take it apart.

Thanks Andrew.

I've taken a guess that it's probably the ICE3BR0665J - SMPS Current Mode Controller. The blue flashing light is the protection mode, when it detects an abnormal power supply condition.

Re: Pioneer HM82 - No power



Hi - please can you point me to where you purchased the service manual? Mine spontaneously powers itself off (only blue flashing light on the front left), but otherwise works perfectly so would like to fix it if possible....
