Dear colleagues greetings I have a samsum trc flat screen TV model CL-21M40MQ KS9C chassis this tv does not turn on and in the repair I ran into the exploded voltage regulator I just got the card soldered in a single pin then I kept checking and found the dz803 the damaged dz801 and dz805 but I don't get them in the store will have a replacement these are the diode codes the dz803 is ZP27B, the dz801 is TZX10B and the dz805 is TZX16C THANK YOU THANK YOU FOR YOUR CONTRIBUTION

Hi friend: those are zener diodes ... the Z801 and the Z805 are 10v ... the Z803 tests with a 12v ... or enters the datascheet and find out features ... but before installing a new lc801 deves make the measurements of rigor and see if there is no short in the secondary ... you must install where the fuse goes a 100w filament lamp as a prtection to prove the source ... but first I must also remove the Q401 salt-hor- of the plate x if it is short ... greetings!

Hi Migo: there you see the pieces that are damaged I hope it serves you. Cheers
