Hum sounds familiar... you eather have a bad connection or your main processor has become corrupted...generally a signal board replacment may be nessarry... something on a tech with a computer interface can do. you have to download data off of old board to put on new board

I have a mitsubishi wd-62525 the power light keeps blinking, and i can't get picture. i unpluge it than want 2min than it stop blinking and i can turn to tv on and get a picture than after 30-40mi


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,

SET TRIES TO TURN, BUT DOESN'T


The RCA P52920BL uses the PTK195 series chassis. The most common reason for the set not turning on is a shorted flyback transformer. To check this, measure the B+ when the set is plugged in - it should be around 145 volts. When you turn the set on, see if the B+ drops down at all. If the flyback is shorted, the set will try to start but the flyback draws too much current. The microprocessor senses this and immediately shuts the set back off. To confirm, unsolder the jumper wire bringing B+ to the flyback and put a 100 Watt bulb in its place. Turn the set on and if the flyback is shorted, the set will now stay on but the bulb will glow as bright as if it was plugged into the wall. If this is the case, replace the flyback. Let me know what you find and we will take it from there.

Mitsu WS-55411 RPTV-power going on and off..won't stay on!


Hello,

It is possible that the Low Voltage power module is defective, however I would first check the High Voltage power supply for bad capacitors (they tend to go bad first). In fact check both boards for bad capacitors (they will look puffy in appearance if they are really defective).

I hope this helps,

Thank you,
