I have a Panisonic PT-52LCX15 I replaced the lamp and now I'm trying to reset the LCD meter, I have tried holding the vol button and the split button and the red lamp light still is on, maybe you could let...


The lamp light should NOT be RED.
The lamp light should be yellow for the lamp timer warning.

There are two ways of retting the lamp timer=
1) on the TV use the vol - button. push until vol goes to zero, then keep holding it down
on the REMOTE push the "split" button

the yellow light should go out indicating that the lamp timer has been reset
if this fails to work,
on the REMOTE, use the "PLAY" button, instead of "split".
you may have to try this a few times to get it to "take". you'll know when the YELLOW lamp light goes out.

However, a RED LAMP light means you lamp is not working or missing.
reseat your new lamp into the TV...and be certain the LAMP DOOR is securely CLOSED.

My Hitachi 50V500A has a large area where the color is turning out to red. Is this a lamp or a complete light engine replacement job?


not the lamp. hitachi knowingly had a defect with the fan not allowing enough air to cool the lamp which has burned the red color lense resulting in the red on your screen. enjoy your new brick thanks to hitachi!

Sony KDF-E55A20 55 in. LCD... Problem red light flashes 5 times


A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck
