Question about Olevia LT27HVX 27 in. LCD Television

Screen goes blank after 2 minutes

No matter what the input signal is. Seems like a problem with the power supply. Sound/tuner continue to work fine.The only way to get the picture back is to cycle the power button on and off. Then it goes blank again after a couple of minutes. Where can I get parts/service for this TV now that Syntax-Brillian has filed bankruptcy?

    Thanks Crikett. I found a service on E-bay that will rebuild your inverter for $89. Seems like a reasonable gamble to take. I'll check out the capacitors and solder joints while I'm in there. I appreciate the quick response though.

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

Your best bet is to take the back off and look if there are and bulged capacitors on the power supply first, also look for cold solder joints on the 24 volt rail that goes to the HV inverter board. If both seem to be ok then you could have a inverter transformer going bad on the inverter board. Let me know how you do>

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Model 2780R intermittant Picture & Sound Failure


The set has loose power conections to the tuner and judging by the model it might have other loose conections in the chassis,the loose conections need to be resoldered and might not be easy to find,try taping the side of the set to see if it reacts while is doing the problem.Be safe and call a technician unless you are familiar with tv service.
