Hitachi 57S715
I hear a relay click and DP40 and DP50 leds light then fade. I assume the tv is going into a shutdown. I monitored the secondary voltages and they all come up normally for a second before shutdown.

Re: Hitachi 57S715
It was quite common for the convergence ic's to go bad, shorted. Try unpluging PPDC plug (has 3 large wires) from the convergence amp board, should be the board on the right with 2 large heatsinks on it. If the tv comes on with no convergence correction, teh stk*** ic's are bad, (only one is most likley bad but replace both) -
Re: Hitachi 57S715
I appreciate your response. I pulled the connector on the convergence board but still in shut down. Vertical IC next possibly?Comment

Re: Hitachi 57S715
check dp32 bridge rectifier and cap cp03 for bad connections.
also does the power led on the front of the tv stay on?
also check the pico fuses, ep01 & ep02, but I think they will be ok.
I have'nt worked on one of these sets in a long time.Last edited by R_J; 04-23-2014, 09:30 PM.Comment

Re: Hitachi 57S715
It has been a long time for me as well. Many a late night trying to figure shutdowns over the years.
Front panel led does not light up at all. I checked the items above for poor solder connections and the two fuses are good.Comment

I extracted the Power and Deflection schematic from the (32meg) manual it might help.Comment

Mainboard: VESTEL 17MB171 Chassis: VES315WNGB - 2D - N52
The TV was stuck on the logo and I couldn't access the update menu.
I couldn't find the firmware for the Hitachi 32HAE2351 and updated it with the Toshiba 32WA2063DG - Vestel 17MB171 firmware.
The image result was good, but the image is inverted.
The image rotation/mirror function doesn't exist in the Menu Server. I can't correct the image.
Do you have the firmware for the Hitachi 32HAE2351 - Vestel 17MB171 motherboard or a solution to rotate the image in... -
hi there,
Got this macbook after liquid damage. Nothing major, cleaned and reflowed what was suspect. Now, the laptop turns on and boots up but shuts off intermittently - sometimes after a few minutes, sometimes after a few hours.
Can be immediately started from keyboard right after. Plug stays orange during this time. No battery.
Gives shutdown cause -128.
Seem to work fine in SMC bypass.
Same shutdown happens with disconnected TP/KB/KBLED/CAM.
