Am I diagnosing the problem correctly?

How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information google.com/+GopakumarGopalan

Check inside for Bulging electrolytic capacitors and replace them. Samsung was famous for it.

This is on protection mode as something is loading it on switch on from the secondary power supply. This might need attention of a qualified service technician.

Magnavox has issues with puffed caps on the power supply. This sounds like its a 32 inch lcd tv. I tried searching for a service manual for this and can't find one. If it is an lcd you need to look at the capacitors on the power supply. If they are puffed up, you will need to replace them with equal or slightly larger valued capacitors. The capacitor values are mfd and voltage printed on the capacitors themselves. You will need a soldering iron to replace them. Lay the tv, if it is an lcd, on a flat surface cushioned by a blanket. Make sure the surface is large enough to support the tv frame, as you don't want to cause damage to the panel. remove the back of the tv. There are numerous screws, and once the back is off, check the power supply pcb for puffed caps. This is the board with the power cord attached. I know in magnavox tv there is a cage covering the power supply, so remove any connectors because you will have to flip the cage housing the power supply to get to the caps. If you feel confident, give it a try. Let me know how it goes

Hello

One amoung this will be your TVs' code.

Three digit remote codes for Philips Magnavox are:-

002/ 009/ 109/ 118/ 209/ 309/ 402/ 408/ 502/ 508/ 510/ 807/ 914/ 917/ 020/ 422/ 919/ 922/ 183/ 184/ 208/ 213

Four digit remote code for Philips Magnavox are:-

0062 0204 0207 0183 0226 0288 0062 0004 0009 0456 0183 0226 0288 0008 0068 0075 0141

NB: Switch OFF and then switch ON your tv with its front panel power switch [NOT BY THE REMOTE CONTROL HANSET]; each time before trying an other code.

Proceedings:-

Direct Code Entry

1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

Code Search If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.

1. Manually turn on the device (TV, VCR, etc.) to be controlled.
2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
5. Press and release MUTE to install the code. The indicator light goes off.

Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search
OK.

Replace your capasitors on the power circuit board.. They are junk to begin with.. They are cheap.. Thats all i can suggest..

hi i have a 50" magnavox that has a problem, i was looking at several websites and i find out the dirfferent posibilities.
