Question about Toshiba TP55H60 55" Rear Projection Television

1 Answer

Set has power, but fails to turn on

Set has power, but will not power up. Power LED flashes repeatedly. I was told that the problem was the power supply from the person who gave it to me. I tried searching for a replacement PB, but they are no longer available.

Your going to need a schematic diagram and some troubleshooting skills here or a quilifyed repair person. This set has several power supply problems as well as sweep dirived power problems. The biggest problem is the STR (I dont remember the other #'s)(ie- STR#####) regulator IC It is alway the first thing that goes bad in these chassis. Now do not get a general replacement as it will blow out as soon as you turn on the set. I've been through this and a half a dozen regulators till I relized that the replacement ics do not have one last digit on the ic that the original did have!! and that one last digit made the ic completely differant. Another common problem here would be The Two filter capacitors off the sweep derived 15 or 18 volt lines Good luck to ya.

What does it mean when the standby light flashes four times on a Sony TV Model # KV-24FV12 ?

These blinks [flashes] are fault indication (Error Codes).From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it.This will make repair easy.These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times.Count it carefully.If you wish to get some details, check the site linked here.It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given.Surf the site with patience.

I have a pioneer pdp4340 the standby light flashes 3 times then repeats over and over after you power up . then it shuts down . i was told it was the x card . by a pioneer thec where is this card located...

Tv is going into fault protection mode at startup. When set turns on relay clicks then turns off with NO OSD-On screen Display and a blinking fault LED. This in indicitive of blown UF capacitors on the PSB-Power Supply Board. On an opened set the PSB is located in the center. You want to look for 2 or more UF Caps on the PSB. A bad Cap will be completely poped or bulding at the top (X) which shold be flat. THe X-main Board is to your right the YSUS Main is to your left

I have a 2006 Sony Wega 50 inch. set turns off after 10 minutes, green led flashes for 45 seconds and then set turns on. it repeats. is the power cord bad?

try to powercycle to reboot, check connections if tightly connected. advise cable provider (if any) to send signal to refresh if have cable box

Red power light flashing; will not turn on.

It is very likely that one of the convergence correction chips has gone south on you (either that or a capacitor). What you want to look for is a swollen capacitor , or a burnt resistor near the two large heatsinks on the signal/convergence PCB. The flashing LED is an indication that the power supply has detected a fault, your mission is to determine what that might be. another thing to check out at the fuses on the power supply PCB (these have labels like FXXX were XXX is a number). If you find an open fuse, that will help determine where to look for the fault.

Another problem with my 52725

It may very well be a connection issue with one of the wire connections as its not giving you a error code. I would double check the wire plug connections

Samsung SlimFit TV made a pop sound while watching it and turned off on its own. Will not turn back on. The power light flashes five times and pauses. I was told maybe the vacuum tube?

A part most likely failed in the power supply or some other board. The flashing light is indicating that the set is in the protect mode.

It is possible that the failed part caused some other damage. You will have to send the set out for sercice.
