The tv wont power on at all


Hello,

Your TV Won't Turn On
If your TV won't turn on, you should check the power cord. Make sure that it is securely in the wall plug. Sometimes the power cord has burned out and needs to be replaced. You may also want to check the batteries in the remote to make sure that they are working properly. If otherwise
Common problem with this TV is the power supply module.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out power transistor and zener diode, if otherwise, Power supply board just die.It can be dead at anytime.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

I hope this will help to solve the problem.....

POWER SUPPLY


zenith are famous for bad soldering even going back to the 80s with the 960-05 boards in the space command sets.
i would pull out the circuit board and check the soldering before doing anything else.

Hitachi rear projection TV clicks when you turn it on, no picture


No schematic, major short, usually the power supply or high voltage circuit, nothing you yourself can do. Pro repair about $450.00. If your in electronics replace the HV transistor first.. then??

Hi, First of all thank you in responding on my issue about my 32" LC320EM82 Emerson TV. I have acquired the service manual from NY TECH TV REPAIR, INC. I've look at it but its all wiring diagram and...


You'll have to check for 12 or 24v coming out of the Power Supply first. No manufacturer gives the power supply diagram. Look for any bulged caps on the PS and replace them. Let me know...

I have a Magnavox 51" Projector TV. Model 51MP392H/17


Hello bullmuscle,

This is a power supply problem, I would suspect the HV power supply because the primary and secondary supplies anymore are tied to the HV power supply. This type of repair requires certain pieces of equipment, to test voltages, look at signals, and to if need be test for shorts in inductors (Switching PS transformer and Flyback transformer). I would not recommend that you try to fix this yourself, The cost for this type of problem is not that expensive and can be done in one evening, if the parts are available. You may be fortunate and it could be just a blown fuse, in the HV or LV power supply circuit

I hope this helps,

Thank you,

RCA Projection TV MM52110 Won't Power Up


Being able to read a schematic and understanding how a TV works are two different things. These chassis that RCA used in these sets can be somewhat complex to troubleshoot. I would geuess that unless the power light comes on at all then you have a dead power supply in the TV.
