I have a Sanyo tv model #FW40D36F, Serial # ME2A1634260047 (A5G24UT). Heard a click sound and it shut off. TV is dead no power no light. Tried restart - nope. Is this likely the power board?

Any suggestions? What are the part numbers for the power and main board?

Sanyo's are notorious for having bad power supply boards. The "click" you heard was probably a capacitor popping.

SOURCE: samsung lcd tv le40r8. tv will not switch on.

The problem is the mainboard tried to turn on TV but failed due to internal circuit problem. Normally, the power supply board is malfuntioned.

Hi

Thanks for using FixYa. Please check the following—

1. Is Power board output +5V?
2. Is J1 (#19 in the right diagram)connector good?
3. Is DC-DC OK, check the voltage at J1 using a multimeter.
4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an IC tester or an oscilloscope to check this IC.

After checking this if it still doesn’t work then check P3 D-sub Input (on the D-board). See this schematic for details--

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Can apps be downloaded onto my sanyo tv model number FW40D36F

No, because it isn't a smart television, just a nice one. Also it doesn't connect to the Internet.

Sounds like you heard a capacitor fail. Check the fuse on the power supply board and look for puffed up electrolytic capacitors on the power supply board and all the other boards in the TV. You can get replacement boards here: TV Parts Universal TV Stands DLP Chips ShopJimmy

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. /

Sanyo Vizon 42" Plasma DP42746 Was using tv when I heard a click and I lost all audio and video, could not change the channel or adjust volume. Tried unplugging and sitting for 10 minutes. Plugged back...

This is a common problem with these TVs. You can download the official Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html. I uploaded it here when I had the same issue with my TV last year. The solution is almost always to replace the Power Board (Y-Main) and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but a repair shop): 1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.
