Hello, any help will be appreciated. I have a Philips television(3QPW862H37A) that was given to me after being hit by lightning(from what I was told). The TV will not turn on. I took the back panel off and looked at the board the power cord is hooked to. All looks fine and well but, there are to glass tubes that are white and hook up just like any other appliance fuse. I took one out and examined it. I can not tell if it is blown or not(partly due to the fact that i can not see through it). Any ideas?

and when you hit it, it sometimes works?
Did you check the solder close to and on the HT transformer?
Please if you are not an electronic engineer, don't open the television, because voltages up to 25.000 volts are there. They can kill you.
Many people are annoyed about demo mode coming out of nowhere and causing problems with many Magnavox televisions there is a simple process which will allow you to disable the demo mode.
Television must be turned off But remain plugged in
First You must place both your fingers on the VOL + and VOL - buttons on the television.
Then Turn on the television while still holding the volume buttons in for about 6 seconds..
The demo mode will now be disabled, Some televisions may turn off after demo mode is disabled just use remote to turn television back on or use programme up and down button on television to turn it on.
This will work even if you don't have the original remote as it requires no remote at all its a simple process and it will work with nearly all models of Magnavox televisions.
Philips sets use a four digit code to control the v-chip. The override code for Philips sets is 0711, although it may say "Incorrect code" the first time to trick you. If "Incorrect code" is displayed, simply enter 0711 again. To use it hit the MENU key to get to the menus. Go up or down until you reach AUTOLOCK or SMARTLOCK, depending on the model, and push the "right arrow" key on the remote. Enter the override code, and enter it a second time if it says it is incorrect.
Once in the AUTOLOCK or SMARTLOCK menu, go to BLOCK, and push the "right arrow" key. Go to BLOCKING OPTIONS and press the "right arrow" key. Go to MASTER DISABLE and press the "right arrow" key so that it says "MASTER DISABLE ON". The v-chip is now reset.
