Need help repairing TV
I want to try to repair my old TV myself, there is just a few blown
parts in the SMPS section. It's a Zenith that doesn't want to turn on; there is no voltage on the primary or secondary side on the xformer at all. I know very little about electronics, so i'm reading up about TV repair on the internet the best I can. The TV repair guy in my town was going to charge me $270 for a complete repair plus wait a month or two for it; NO WAY. If I can't then the TV is heading for the dumpster. The CRT should is fine. I found this main board: http://www.newcountryenterprises.com/rca.htm Could I take parts from the power supply section and transfer them over to my board? From the looks of the pic and the corresponding part list on the left of the pic; it seems like the same SMPS build. I'm guessing it is the STR-53041 or the driver transistor (QX4301) is fried, if it is more than that, at least I have more parts to take from this cheap board. I can't find anything about this board I want to buy (9-01616-01) would anyone here know where I can find more info about it or a schematic? It's worth a shot. Thanks in advance |

The replacement board may be NLA, check at L/G.com for availabilities. L/G
own Zenith and their parts related facilities. Best bet is for you to find a service manual, from L/G or SAMS Photofact. May be able to find one at the local library or online. The service manual and schematics will indicate part references and voltage measurements. Post the complete model number back on this N/G. Also any other diagnostics that you have done. A great group of informed personnel will assist you as much as possible via this means. Also check out wa6ati.com for additional assistance. This is a site ran by service technicians and is extremely informative. wrote in message oups.com... I want to try to repair my old TV myself, there is just a few blown parts in the SMPS section.
