Hi,

Brand : Toshiba
Model : 43JH9UM equivalent to 43CJH9UR, 43JH9UE, 43JH9UT
Description : 43" RPTV (R,B,G Guns), 8 Years old
Service Manual and Circuit : http://www.scribd.com/doc/65312424/43jh9um
Power Board : PD2026 Pg.43 of Service Manual

Problem : No High Voltage, Low voltage is present

History :
  1. The extension wire connected to the tv shorted out,
  2. but the tv was fine until i closed it and reopened,
  3. there was no power, fuse was blown, changed it but no power again,
  4. took to some of the local electricians they denied help with projection tv's, one of them replaced the power resistor (R811) which seemed to fix the power supply
  5. but only the leds and power light was on there was no high voltage no hissings, the caps wont charge or anything
  6. if i pressed the power button on the remote only the leds would turn off and on

My Experience :

Soldering, and meter testing(using google) from 1-10 il give myself a 3.

Need Help Thanks !!
