Ok, first let excuse me for the first solution that I make in the 53UDX10B 53 in. I was thinking was a DLP Television but it was a Projection Television.
The Projection Televisions has others problems, so maybe it is that a Technician must has to solder (weld or give weld points) in some boards (PCBs) inside the TV, (the Main PCB and/or the Sound PCB) and/or perhaps has to change a capacitor (C 33uf 16v) that maybe it is exploded. Because that happen with those old Projection TVs.
It is the same with the 53UWX10B.
For all inquiries please call: 1-800-HITACHI and tell then the problem.
They maybe give you a better solution.

No picture or sound with a red flashing power light. Have replaced the convergence IC's but no change (do not have the chirpint sound). Removed main power board & green LED does not light up


On that model the conv IC is usually not the solution. I believe its the blown capacitor problem with is an easy fix. Check the site www.TvRepairKits.com for a repair kit.

Tv turns off red light flashes and i hear a chriping sound


This problems is also parts of tv convergence board have dead 2 STK convergence ICS and some or all the resistors dead too.This problems the 2 STK and some or all it resistors are completely dead that why u only have red flashing light and chirping sound only.If your tv have any life function left of the tv convergence board u would have only mis alignments of colors R,G,B lines,have colors shadows or 3D pictures look alike.The shop,will cost like $300-350 to get the tv convergence board fixed also fixed this problems too.

DP23 LED not lit on deflection board no picture on tv


Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

Good Day, Butchilee,
Sounds like you have patience, hope your TV has some trace left. Hit recommends that you replace the originals with
STK-392-150's and the resistors. Replace said items with care then back down on the screen/ focus controls and gradually bring the screens up until you have pic, adjust focus. Go into customer menu and adjust color down, set brightness to 50%, contrast to 100%. Then go back and adjust the screens for proper, black/white, tracking. AND It's best to double check the soldering connections.
Good Luck, Big Irish.

Progress


I would check the red CRT PC Board for a bad connection on the socket. The focus wire plugs into that socket. And a corroded socket, cracked solder or a faulty focus lead connection can cause that symptom.

No raster, no sound on 53UWX10B


double check the wire connections, as the filaments not being lit makes me thing a wire isnt connected properly, or one may have been loosend while doing the convergence repairs.

Zenith iqc50h95 50 in rear proj


Rainman, can`t really be of any great help on this one, both techs can be right, the chirp is exactly as you thought, the set is trying to come on but there is a short in the set and it`s shutting down because of the short, could be convergence, low voltage power supply, high voltage power supply, until a tech gets in there and starts un-loading circuits it`s impossible to say where the short is, gonna have to call someone out for this one, good luck with it, BMW Rider
