| I Have same unit. If you still have & proves unfixable, my (customer) unit needs board with VGA (PC input), HDMI and Component Input jacks (someone's attacked some parts with a soldering iron - certain OSD messed up/won't adjust and no/bad video, both vary with source chosen. The info within quotes is nomenclature off of part in question.
IC302 top line: "3843B," bottom line: LOGO="ST" then "Z524." R323 "201" (R453=same). D302 "A2" (D401 thru D404=same). R330 "1001" (R419 & R458=same). |

|
| I have a Digitrex JTF3227P 32" LCD HD TV with a bad power supply. There are several components that were physically destroyed in the PSU by a "surge": IC302 R323 D302 and R330. The PSU is manufactured by "HAIDER" and is model # HDAD200W301 rev 4.3. Does anyone have a schematic or can tell me the values of the missing components? "Digitrex" appears to be out of business, although they still have a website, the phone # is disconnected. I have been unable to locate the PSU manufactuer as well. Any help would be greatly appreciated! | |
